GENERAL INFORMATION Service Techniques General The words ’front’, ’rear’, ’right-hand’ and ’left-hand’ used in this manual refer to the different parts of the machine as viewed from the Operator’s seat, when facing the steering wheel. Clean the exterior of all components before starting any type of repair. Dirt and abrasive dust can reduce the efficient working life of a component and lead to costly replacement. Time spent on the preparation and cleanliness of working surfaces will pay dividends in making the job easier and safer and will result in overhauled components being more reliable and efficient in operation. Use cleaning fluids which are known to be safe. Certain types of fluid can cause damage to O-rings and cause skin irritation. Solvents should be checked that they are suitable for the cleaning of components and also there is no risk to the personal safety of the user. When replacing component parts, use the correct tool for the job. Cleaning

Caution: Care should be exercised to avoid skin rashes, fire hazards, and inhalation of vapours when using solvent type cleaners.

Clean all parts thoroughly using solvent type cleaning fluid. It is recommended that parts be immersed in cleaning fluid and agitated until all old lubricant and foreign material is dissolved and the parts are thoroughly cleaned. Bearings Remove bearings from cleaning fluid and strike flat against a block of wood to dislodge solidified particles of lubricant. Immerse again in cleaning fluid to flush out particles. Repeat above operation until bearings are thoroughly clean. Dry bearings using moisture-free compressed air. Be careful to direct air stream across bearing to avoid spinning. Do not spin bearings when drying . Bearings may be rotated slowly by hand to facilitate the drying process. Housings

Caution: Care should be exercised to avoid inhalation of vapours and skin rashes when using alkali cleaners.

Thoroughly clean interior and exterior of housings, bearing caps, etc. Cast parts may be cleaned in hot solution tanks with mild alkali solutions, provided these parts do not have ground or polished surfaces. Parts should remain in the solution long enough to be thoroughly cleaned and heated. This will aid the evaporation of the cleaning solution and rinse water.

Parts cleaned in solution tanks must be thoroughly rinsed with clean water to remove all traces of alkali. Cast parts may also be cleaned with a steam cleaner. All parts cleaned must be thoroughly dried immediately by using moisture-free compressed air or soft lint—free absorbent wiping rags, free of abrasive materials such as metal filings, contaminated oil or lapping compound. Inspection The importance of careful and thorough inspection of all parts cannot be overstressed. Replacement of all parts showing indication of wear or stress will eliminate costly and avoidable failures at a later date. Bearings Carefully inspect all rollers, cages and cups for wear, chipping, or nicks to determine fitness of bearings for further use. Do not replace a bearing cone or cup individually without replacing the mating cup or cone at the same time. After inspection, lubricate the bearings with suitable clean oil and wrap in clean lint—free cloth or paper to protect them until installed. Oil Seals, Gaskets, Etc. Replace O-rings, seals or gaskets whenever they are disturbed. Never mix new and old seals or O-rings, regardless of condition. Always lubricate new seals and O-rings with suitable clean oil before installation. Replacement of spring-load oil seals, O-rings, metal sealing rings, gaskets and snap rings is more economical when the unit is disassembled than premature overhaul to replace these parts at a future time. Further loss of lubricant through a worn oil seal may result in failure of other more expensive parts of the assembly. Sealing members should be handled carefully, particularly when being installed. Cutting, scratching or curling under the lips of seals seriously reduces their efficiency. When assembling new metal type sealing rings, these should be lubricated with a light grease to stabilise rings in their grooves for ease of assembly of mating members. Gears and Shafts Examine teeth on all gears carefully for wear, pitting, chipping, nicks, cracks or scores. If gear teeth show spots where case hardening is worn through or cracked, replaced with new gear. Small nicks may be removed with a suitable hone. Inspect shafts and quills to make certain they are not sprung, bent or spline-twisted, and that shafts are not bent. Housings, Covers, Etc. Inspect housings, covers and bearing cups to ensure that they are thoroughly clean and that mating surfaces, bearing bores, etc. are free from nicks or burrs. Check all parts carefully for evidence of cracks or conditions that would cause subsequent oil leaks or failures.

GENERAL INFORMATION Hoses and Tubes Always replace hoses and tubes if the cone end or the end connections on the hose are damaged. When installing a new hose, loosely connect each end and make sure the hose takes up the designed position before tightening the connection. Clamps should be tightened sufficiently to hold the hose without crushing and to prevent chafing. After hose replacement to a moving component, check the hose does not foul by moving the component through the complete range of travel. Make sure any hose which has been installed is not kinked or twisted. Hose connections which are damaged, dented, crushed or leaking, restrict oil flow and the productivity of the component being served. Connectors which show signs of movement from the original swagged position have failed and will ultimately separate completely. A hose with a chafed outer cover will allow water to enter. Concealed corrosion of the wire reinforcement will subsequently occur along the hose length with resultant hose failure. Ballooning of the hose indicates an internal leakage due to structural failure. This condition rapidly deteriorates and total hose failure will soon occur. Kinked, crushed, stretched or deformed hoses generally suffer internal structural damage which can result in oil restriction, a reduction in the speed of operation and ultimately hose failure. Free moving, unsupported hoses must never be allowed to touch each other or related working surfaces. This causes chafing which reduces hose life.

slings and hooks. Use lifting eyes provided for this purpose. Never run the engine in confined spaces which are not equipped with adequate ventilation for exhaust gas recirculation. Never bring your head, body, arms, legs, feet, hands or fingers near fans or rotating belts. Always loosen the radiator cap very slowly before removing to allow pressure in the system to dissipate. Coolant should be topped up only when the engine is stopped. Do not fill the fuel tank when the engine is running. Never adjust the fuel injection pump when the machine is running. Never lubricate the machine when the engine is running. Fluid coming out from a very small port may be invisible and strong enough to penetrate the skin. Never use your hands to check for leaks, always use a piece of cardboard or wood for this purpose.

Precautions During Work

• • • •

• • •

• • • • • • • •

Do not walk or stop under raised loads or machine parts supported by hydraulic cylinders or ropes only. Always keep the machine handrails and access steps free of oil, grease or dirt to prevent falls or slips. When entering or leaving the cab, always face the machine. Never turn your back. When carrying out operations at hazardous heights (greater than three metres from the ground), always use type-approved safety belts or fall preventing devices. Do not enter or leave the machine when the engine is running. Allow the engine to cool before servicing. Do not work on the machine when under or between the wheels when the engine is running. If work is required while in this position, stop the engine, apply the parking brake and chock the wheels to prevent accidental movement of the machine. Do not carry out any maintenance or repairs without adequate lighting. Do not connect wet plugs or sockets. Signs or safety decals should never be removed, obscured or unreadable. Always stop the engine and disconnect the battery before maintenance or service. Do not lubricate or clean any components while still moving. Before carrying out operations on hydraulic lines under pressure, always make sure the line has been depressurized and does not contain hot fluid. Do not carry out any repairs to the fuel system with the engine running. Handle all flammable or dangerous substances with care.

• •

Make sure that no tool, cloth or other objects have been left within compartments with moving parts or in which suction and cooling air circulates. After work , never leave the machine in a potentially dangerous state.

Fire Prevention Engine fuel can cause an explosion or fire: — Never fill with fuel when the engine is running. — Do not smoke during re-fuelling. — Take all necessary safety measures when welding, grinding or when working near a naked flame. • Use a non flammable product for cleaning parts. A spark or flame can cause the hydrogen in the battery to explode. To prevent any risk of explosion, obey the following instructions: — Remove the battery isolator key (optional). — When disconnecting the battery cables, always disconnect the negative (-) cable first. — To connect the battery cables, always connect the negative (-) cable last. — Never short circuit the battery terminals with metal objects. — Do not weld, grind or smoke near a battery. • The electrical system or engine exhaust may produce sparks. Before using the machine in an area which may contain inflammable vapours, make sure there is adequate ventilation. • Clean the machine and remove all debris and material which may catch fire. • Check for leaks. Replace damaged hoses, pipes and unions. Clean the machine after any repair work before operating.

Burn Prevention

Battery electrolyte causes severe burns. The battery contains sulphuric acid. Avoid any contact with skin, eyes or clothing. If contact is EXTERNAL, rinse with water. If contact is INTERNAL, drink large quantities of water or milk. Seek medical assistance immediately. If contact is with in the EYES, rinse with water for 15 minutes. Seek medical assistance immediately. When the electrolyte of a battery is frozen, it can explode if you attempt to charge the battery or if you try to start the engine using a booster battery. Always keep the battery charged to prevent the electrolyte freezing. Batteries produce explosive gases. Keep all flames, sparks, and cigarettes away. Provide adequate ventilation when charging a battery or using a battery in an enclosed space. Always protect your eyes when working near a battery. Boiling coolant solution can spray out if the radiator cap is removed while the system is still hot. To remove the cap, allow the system to cool down, turn the cap to the first notch and wait until there is no more pressure. Then remove the cap.

Personal Safety Considerations Wearing wrong clothes or carelessness in dress can cause accidents. Make sure to wear suitable clothing when servicing the machine.

0–01–20

GENERAL INFORMATION Some jobs require special protective equipment, always use protective equipment when required. Skin Protection Used oil may cause skin cancer. Follow work practises that minimize the amount of skin exposed and length of time used oil remains on the skin. Eye Protection Eye injury may cause loss of vision. Always wear suitable eye protection when chiselling, grinding, welding, painting or working on any pressurized fuel or oil system. Breathing Protection Fumes, dust and paint spray may be harmful. Always wear suitable breathing apparatus when these are present. Hearing Protection Loud noises may damage hearing and the greater the exposure the greater the damage. If the noise level is excessive, wear suitable ear protection. Lifting Protection Avoid injury by correct handling of components. Make sure you are capable of lifting the object, if in doubt seek assistance. Hand Protection It is advisable to use a protective cream before work to prevent irritation and skin contamination. After work, clean hands with soap and water. Solvents such as mineral spirit and kerosene may harm the skin. Foot Protection Substantial or protective foot wear with reinforced toe caps will protect feet from falling objects. Oil resistant soles will assist in avoiding slippage. Special Clothing For certain work it may be necessary to wear flame or acid resistant clothing.

Equipment Safety Considerations Machine Guards Before using any machines, make sure the machine guards are in position and are serviceable. These guards prevent anything from coming into contact with any moving parts and prevent injury from any flying debris. Lifting Devices Make sure lifting equipment such as chains, slings, hooks and eyes are thoroughly inspected for damage before use. If in any doubt about the weight capacity required, use stronger equipment than is necessary.

Do not use compressed air to blow dust, filings or dirt from the area being worked in unless the correct nozzle is fitted. Hand Tools Injuries may result from using defective tools. Always use the correct tools for the job, use of incorrect tools mat result in damage to the machine or personal injury. When removing or installing hardened pins, use a copper or brass drift. Do not use a hard faced hammer. When carrying out a repair procedure, always use the Special Tools recommended.

General Considerations Solvents Use cleaning fluids and solvents that are known to be safe. Certain types of fluids may cause damage to components such as seals and may cause skin irritation. Solvents should be checked that they are suitable for the cleaning of components and individual parts and will not affect the personal safety of the user. Fire Fire has no respect for persons or property. The destruction a fire may cause is not always fully realized. Always be on guard against fire hazards. Do not smoke when working on the machine. Work cleanly and dispose of waste material into suitable containers. Identify the location of the nearest fire extinguisher and know how to operate it. In the event of a fire, do not panic, warn those near and raise the alarm. Do not use a naked flame near the fuel tank, battery or any other components. First Aid Dirt, grease and fine dust may settle on the skin and clothing. If a cut, burn or abrasion is left unattended, infection may occur. Seek medical attention immediately. Cleanliness Cleanliness of the hydraulic system is essential for optimum performance. When carrying out service and repairs, plug all hose ends and connections to prevent contamination. Clean the exterior of all components before carrying out any repairs. Dirt and abrasive dust can reduce the efficiency and working life of a component. Use of a high pressure washer or steam cleaner is recommended.

Compressed Air The pressure from a compressed air line can often exceed 100PSI (690 kPa). This is safe to use but incorrect use may cause injury.

MAIN HYDRAULICS

Caution: If serious hydraulic pump failure is suspected, do not run the hydraulic pump for longer than is absolutely necessary to determine its condition. If metal fragments are found in the hydraulic lines, oil reservoir, hydraulic pump outlet port, suction screen and/or return oil filter. DO NOT restart the hydraulic pump. Replace the hydraulic pump and clean the hydraulic system. For additional information, refer to CLEAN THE HYDRAULIC SYSTEM, PAGE F06–01–89 in this section. Failure to follow this instruction, may result in further damage to the hydraulic system.

Note: Hydraulic gauges will have a + or – 5% tolerance. Testing at 200 bar it is possible to have a 10 bar discrepancy in the readings. Allow for this if using two separate gauges. Use the same gauge for all tests if possible.

MAIN HYDRAULICS DIAGNOSING AND TESTING — HYDRAULIC OIL CONTAMINATION

BHN0601TA

Hydraulic Oil Contamination Contamination in the hydraulic system is a major cause of the malfunction of hydraulic components. Contamination is any foreign material in the hydraulic oil. Contamination can enter the hydraulic system in several ways: • When the oil is drained or any line disconnected. • When a component is disassembled. • From normal wear of the hydraulic components. • From damaged or worn seals. • From a damaged component in the hydraulic system. All hydraulic systems operate with some contamination. The design of the components in this hydraulic system permits efficient operation with a small amount of contamination. An increase in this amount of contamination can cause problems in the hydraulic system. The following list includes some of these problems. • Cylinder rod seals leak. • Control valve spools do not return to neutral. • Movement of control valve spools is difficult. • Hydraulic oil becomes too hot. • Pump gears, housing, and other parts wear rapidly. • Relief valves or check valves held open by dirt. • Quick failure of components that have been repaired. • Cycle times are slow; machine does not have enough power. If any of the above problems are encountered, check the hydraulic oil for contamination. See Types of Contamination. If contamination is found, use the Portable Filter to clean the hydraulic system. For

additional information, refer to CLEANING THE HYDRAULIC SYSTEM, PAGE F06–01–89 in this section.

Types of Contamination There are two types of contamination: • Microscopic • Visible Microscopic contamination occurs when very fine particles of foreign material are in suspension in the hydraulic oil. Microscopic particles are too small to see or feel. Microscopic contamination can be found by identification of the following problems or by testing in a laboratory. Examples of the problems are: • Cylinder rod seal leak. • Control valve spools do not return to NEUTRAL. • The hydraulic system has a high operating temperature. Visible contamination is foreign material that can be found by sight, touch, or odour. Visible contamination can cause a sudden failure of components. Examples of visible contamination: • Particles of metal or dirt in the oil. • Air in the oil. • The oil is dark and thick. • The oil has the odour of burnt oil. • Water in the oil. Note: If water is present in the oil, flush the water from the hydraulic system. For additional information, refer to FLUSHING WATER FROM THE HYDRAULIC SYSTEM, PAGE F06–01–91 in this section.

MAIN HYDRAULICS GENERAL PROCEDURE — HYDRAULIC CYLINDER RING LUG EXTRACTION

BHF0601GD

Extraction A failed ring lug can be removed using the following process: 1. Through the insertion hole, centre punch the ring as near to the centre of the ring as possible.

TV040729

2. Refering to the diagram, use a size (B) drill, and drill through the ring and into the gland to the depth (C).

Caution: The drilled hole must not be drilled deeper than shown, or the drill may break through the gland, in which case the gland must be scrapped.

3. Cut off a section of ring or piano wire of diameter (A), to the length (D) and insert it into the blind hole. This will now take the place of the lug and drive the broken ring out in the normal way.

F06–01–97

MAIN HYDRAULICS 4. After complete withdrawal of the ring, pull the piston rod sharply out until it contacts the gland, this will normally remove it. Note: • In the event of failure to remove the gland in this way due to burrs around the ring grooves, it is suggested that either a hydraulic press or a hand operated pump be used to remove the gland.

Warning: If a hydraulic pump is used to dismantle the gland from the cylinder, extreme care must be taken to purge all air from the cylinder before pressurisation. COMPRESSED AIR INSIDE THE CYLINDER AT THIS STAGE IS EXTREMELY DANGEROUS. Robust restraints should be attached to both the piston rod-eye and the cylinder mounting, as a further precaution. Failure to follow this instruction may result in personal injury.

ELECTRICS GENERAL PROCEDURE — BATTERY CHARGING

BHJ0901GB

Special Tools Battery charger — For slow and standard charging it is necessary to use a constant current type, with an output of at least 14 amps and an upper voltage limit of 50 volts per battery. (A constant voltage charger limited to 16 volts will not recover a battery with an open circuit voltage below 11 volts). For fast charging, an output of 35 amps is required. Digital voltmeter — with a precision of 0.2% or better and reading to two decimal places, over the range 0 to 19 volts. High-rate discharge tester — with a capacity of at least 500 amps. Thermometer — covering the range of −10°C to 110°C (14°F to 230°F).

General Description The machines are equipped with a single or twin batteries. In temperate climates no maintenance will be needed throughout the life of the battery, unless a charging system fault develops, which may cause some water loss. In hot climates there will be some water loss. It is therefore good practice to check the electrolyte level every 250 hours. Twin

ELECTRICS Battery inspection before test or charge Reject the battery if: 1. The electrolyte is excessively low. 2. Electrolyte levels vary by more than 20 mm (0.8 in) between cells. 3. Battery case, lid or mountings are cracked or damaged. 4. Terminals are damaged or loose in the case.

Slow charging of the battery

Caution: Use a battery charger of constant current type with an output of at least 14A and an upper voltage limit of 50V per battery. Caution: Parallel charging is not recommended, therefore on machines fitted with twin batteries, charge each one individually.

1. Remove the battery from the machine. For additional information, refer to BATTERY (SINGLE), PAGE J09–01–11 or BATTERY (TWIN), PAGE J09–01–13 in this section. 2. If a battery has been neglected and produces an open circuit voltage of 11V or less, it will be completely discharged and the plates will have suffered sulphation. Initially the battery will draw higher than normal voltage but lower than specified current. CURRENT FOR SINGLE BATTERY

9A

CURRENT FOR TWIN BATTERY

14A

3. Connect the battery charger to the battery. Make sure the polarity of the connections is correct and connect the (+) positive connection first. 4. After 30 minutes, check the charging voltage (the charging current may still be lower than specified). Below 12V reject the battery. Above 16V reject the battery. Between 12V and 16V, continue with charging process for 15 hours.

Warning: Check the battery temperature regularly and if it reaches 60°C (140°F) stop the charging process.

5. Set the battery charger to OFF. Disconnect the cables from the battery. Make sure you disconnect the (-) negative cable first. 6. Allow the battery to stand for 24 hours. 7. Load test the battery. For additional information, refer to DIAGNOSING AND TESTING – BATTERY, PAGE J09–01–7 in this section.

Fast charging of the battery

Caution: Use a battery charger of constant current type with an output of at least 35A. Caution: Parallel charging is not recommended, therefore on machines fitted with twin batteries, charge each one individually. Caution: The standard charge should always be used in preference to the fast charge procedure.

1. Remove the battery from the machine. For additional information, refer to BATTERY (SINGLE), PAGE J09–01–11 or BATTERY (TWIN), PAGE J09–01–13 in this section.

Caution: Never use the fast charge procedure for batteries producing an open circuit voltage of 11V or less.

FRONT AXLE AND STEER SYSTEM is made to allow the steering to take priority over other hydraulic requests. When a steering request is made, the oil is supplied to the front steering cylinder (1) through the hose (9) (steering left) or hose (10)

(steering right) to move the cylinder piston rod in the required direction. Excess oil is returned to the hydraulic oil reservoir through hose (2).

The four-wheel steering system consists primarily of a front steering cylinder (1), orbitrol steering motor

(4), steering priority/unloader valve (8), rear hydraulic cylinder and a changeover valve (see changeover

L11–04–3

FRONT AXLE AND STEER SYSTEM valve overview). Oil is supplied to the orbitrol steering motor (4) from the steering priority/unloader valve (8) through the hose (7). Hose (5) is used to sense when a steering request is made to allow the steering to take priority over other hydraulic requests. When in two-wheel steer mode and a steering request is made, the oil is supplied to the front steering cylinder (1) through the hose (9) (steering left) or hose (10) (steering right) to move the cylinder piston rod. Hose (6) is linked directly to the changeover valve and when

in two-wheel steer mode, the flow of oil is allowed to travel directly through the changeover valve and back to the front steering cylinder (1) through hose (10) therefore bypassing the rear steering cylinder and completing the circuit. The system also incorporates two proximity switches (one on each axle). These proximity switches enable the system to detect when the wheels are in the straight ahead position, allowing the system to avoid the rear wheels being locked when not aligned correctly.

The changeover valve is used to change the steering modes between two-wheel steer, four-wheel steer and crab steer. This is achieved by the use of two electrically controlled solenoids, which are installed to the changeover valve body. When activated, these solenoids actuate the valves in the changeover valve

body and change the direction of the oil flowing through it depending on which steering mode is selected. Hose (2) is linked directly to the orbitrol steering motor while hose (1) is linked to the front steering cylinder.

When four-wheel steer is selected, the solenoids on the changeover valve (3) are actuated and oil is not permitted to flow between port (P) and port (T) and is redirected. Ports (A) and (T) of the changeover valve now allow oil to flow between them. Ports (P) and (B) will also allow oil to flow between them. As an example, when the steering wheel is moved to the right

the orbitrol steering motor will move the oil into port (P) and out of port (B) and into the rear steering cylinder (5). As the pressure moves the rear steering cylinder piston rod, oil is forced out from the steering cylinder and through port (A), out of port (T) and into the front steering cylinder. This system allows for proportional movement of the front and rear steering cylinders.

As the pressure moves the front steering cylinder piston rod, oil is forced out

from the steering cylinder and through port (T) of the changeover valve, out of port (B) and into the rear steering cylinder piston rod. As the pressure in the rear steering cylinder (5) moves the piston rod, oil is forced out the opposite end of the steering cylinder and through port (A) of the changeover valve, out of port (P) and back to the orbitrol steering motor. This system allows for proportional movement of the front and rear steering cylinders.

Wheels and Tyres

PREPARATION

Before mounting a tyre on a used rim, ensure the flange area (particularly the bead seat area) is clean and smooth. Remove any build-up of rust, corrosion or old rubber with a chisel or wire brush. Thoroughly inspect the inside of the casing for damage or foreign material. Ensure that both tyre and tube are completely dry, as moisture deteriorates the cord fabric of the tyre and may result in eventual failure of the tyre. Lubricate both beads with a thin solution of vegetable oil soap in water, or equivalent rubber lubricant recommended for this requirement. (NEVER use petroleum-based solutions or silicones).

• • • • • • •

• • • • • • • • •

NEVER re-inflate a tyre that has been run flat or seriously underinflated without removing and checking for tyre, tube or rim damage. NEVER rework, weld, heat or braze rims. NEVER install tubes that are buckled or creased. NEVER use a tube in a casing larger or smaller than that for which the tube was designed by the manufacturer. NEVER hit the tyre or rim with a hammer. NEVER mount a tyre on a rim where any parts show cracks, damage, or have been repaired by welding or brazing. ALWAYS use specialised tools, as recommended by tyre suppliers, for mounting and demounting of tyres. ALWAYS inspect inside of tyres for loose cords, cuts, penetrating objects, or other carcass damage. Repairable damage should be repaired before installing the tube. Tyres with irreparable damage must be discarded. ALWAYS clean and inspect rims. ALWAYS check rim diameter to ensure it exactly matches the rim diameter moulded on the tyre. ALWAYS inspect the inside of the tyre for dirt, liquids, or foreign material and remove before installing the tube. ALWAYS use new tubes in new tyres. ALWAYS check to ensure the tube is clean before installing in the tyre. ALWAYS lubricate with approved tyre mounting lubricant. Never use anti-freeze, silicones or petroleum-based lubricants. ALWAYS use an extension hose with a gauge and a clip-on chuck so that the operator may stand aside during inflation. ALWAYS inspect valve cores and sealing cap for proper air retention. Replace damaged or leaky cores or caps. ALWAYS inflate tyre to the tyre manufacturer’s recommended cold operating pressure.

Wheel Nuts If a wheel is removed and replaced for puncture repair or any other reason, the wheel nuts must be tightened to the torques given in the Specifications Section of this manual and checked daily until stabilised.

M12–01–1

Warning: Many machines use special wheel nuts and washers, which must never be substituted by a standard wheel nut. When fitted, always use the special washers under the rear wheel nuts. If either the nut or washers are lost they must only be replaced with genuine Aftercare parts.

DRIVETRAIN AND BRAKES The transmission and torque converter function together through a common hydraulic system. The charging pump (29) draws oil through the suction oil strainer (28) and directs it to the oil filter (22). Protecting the filter from system pressure in excess of 4.3 Bar (62 PSI) is a by-pass valve (21). A pressure regulating valve (12) maintains the pressure for the control valve and clutches at 20 bar (290 PSI) and excess oil is returned to the torque converter circuit.

The torque converter is protected from pressures over 10 bar (145 PSI) by a safety valve (10). After leaving the torque converter, the oil flows through the oil cooler (6) then on to lubricate and cool the transmission bearings and clutches. The oil drains back to the transmission sump (44) under gravity. A torque converter by-pass valve (5) will open if the pressure difference across the torque converter and oil cooler is greater than 4 bar (58 PSI), assisting start up from cold and protecting from high RPM).

DRIVETRAIN AND BRAKES Transmission Assembly and Controls 1. The Torque Converter and Charging Pump Drive Section

TV040547

Engine power is transmitted from the engine flywheel to the impeller through the impeller cover. This element is the charging pump portion of the hydraulic torque converter and is the primary component which starts the oil flowing to the other components which results in torque multiplication. This element can be compared to a centrifugal pump in that it picks up fluid at its centre and discharges at its outer diameter. The torque converter turbine is mounted opposite the impeller and is connected to the turbine shaft or directional clutch shaft. This element receives fluid at its outer diameter and discharges at its centre. The reaction member of the torque converter is located between and at the centre of the inner diameters of the impeller and turbine elements. Its function is to take the fluid which is exhausting from the inner portion of the turbine and changes its direction to allow correct entry for recirculation into the impeller element. This recirculation will make the converter multiply torque.

The torque multiplication in function of the balding (impeller, turbine and reaction member) and the torque converter output speed (turbine speed). The torque converter will multiply engine torque to its designed maximum multiplication ratio when the turbine shaft is at zero RPM (stall). Therefore we can say that as the turbine shaft is decreasing in speed, the torque multiplication is increasing. In the impeller cover a splined shaft is installed which runs inside and through the turbine shaft to drive a hydraulic pump which is fitted at the back of the transmission. Since the shaft is connected to the centre of the impeller cover, the hydraulic pump speed will be the same as engine speed. The rear side of the impeller cover has a tanged drive which drives the transmission charging pump located in the converter housing. The transmission charging pump speed is also the same as the engine speed.

N13–01–9

DRIVETRAIN AND BRAKES 2. Input or Directional Clutches

2

TV040548

The turbine shaft driven from the turbine transmits power to the forward or reverse clutches. These clutches consist of a drum with splines and a bore to receive a hydraulic actuated piston. The piston is oil tight by the use of sealing rings. A steel disc with internal splines is inserted into the drum and rests against the piston. Next, a friction disc with splines at the outer diameter is inserted. Discs are alternated until the required total is achieved. A backing plate is then inserted and secured with a snap ring. A hub with outer diameter splines is inserted into the splines of discs with teeth on the inner diameter. The discs and hub are free to increase in speed or rotate in the opposite direction as long as no pressure is present in that specific clutch. To engage the clutch, the control valve which is fitted on the side of the transmission will direct oil under pressure through tubes and passages to the selected clutch shafts. Oil sealings are located on the clutch shafts. These rings direct the oil through a drilled passage in the shaft to the desired clutch.

Pressure of the oil forces the piston and discs against the backing plate. The discs with splines on the outer diameter clamping against discs with teeth on the inner diameter enables the drum and hub to be locked together and allows them to drive as one unit. When the clutch is released, a return spring will push the piston back and oil will drain back via the control valve into the transmission sump. The powershift transmission has one reverse clutch and two forward clutches (forward Low and forward High). This, in combination with the two range clutches, results in the transmission having 4 forward speeds and 2 reverse speeds. The engagement of the directional clutches is modulated; which means that clutch pressure is built up gradually. This will enable the unit to make forward, reverse shifts while the vehicle is still moving and will allow smooth engagement of drive. The modulation is controlled electronically in the control valve.

N13–01–10

DRIVETRAIN AND BRAKES 3. The Range Clutches

TV040549

Once a directional clutch is engaged power is transmitted to the range clutches (1st or 2nd). Operation and actuation of the range clutches is similar to the directional clutches. The engagement of the range clutches is also modulated to enable a smooth engagement.

The modulation for these clutches is achieved by means of a restrictor valve fitted in the control valve which is controlled electronically and which limits oil flow to the clutch during shifts. In the clutch itself the plate before the end plates is dished to build up the clamping force of the clutch gradually.

N13–01–11

DRIVETRAIN AND BRAKES 4. The Output Section

TV040550

With a range clutch engaged power is finally transmitted to the output shafts. The powershift transmission can have an upper output or lower output at the rear side of the unit, and a lower output at the front side. Output rotation of the rear upper output is opposite the engine rotation when the forward clutch is engaged, while output rotation of the lower rear output and the front output is the same as the engine rotation with the forward clutch engaged.

The lower front output has an axle disconnect clutch to enable four-wheel drive. The clutch is similar to the other clutches except that it has no modulation. The disconnect clutch is controlled electronically. The clutch is engaged with an electrical signal.

TV040551

Operation of the valve is as follows: (Refer to transmission hydraulic circuit) The control valve has 6 solenoids, 6 shift spools, a pressure reducer, an electronic controlled modulation valve, an accumulator, a pressure booster and a speed sensor. Regulated pressure 20 bar (290 PSI) is directed to the shift spools, pressure booster (25) and pressure reducer (13). In the pressure reducer (13), regulated pressure is reduced to 5.5 bar (80 PSI). This reduced pressure is used as supply for the solenoids (11) and electronic controlled modulation valve (23). When activated, the electronic controlled modulation valve (23) will give an output pressure curve from 0 to 5,5 bar (0 to 80 PSI). This pressure curve is multiplied in the pressure booster (25) so that a curve from 0 to 20 bar (0 to 290 PSI) is available for the directional clutches. Between the electronic controlled modulation valve (23) and the pressure booster (25) is an accumulator (26) to dampen any hydraulic vibration. When forward is selected the electronic controlled modulation valve (23) and the neutral/forward solenoid (14) are activated. The pilot pressure of the neutral/forward solenoid will move the shift spool so that the forward clutch (34) or (36) can be fed with modulated pressure. If the High/Low solenoid (16) is not activated, the forward high clutch (36) is engaged. If it is activated, the Forward Low clutch (34) is engaged. When reverse is selected the electronic controlled modulation valve (23) and the neutral/reverse

solenoid (15) are activated, the pilot pressure of the neutral/reverse solenoid will move the shift spool so that the reverse clutch (32) can be fed with modulated pressure. The shift spools from forward and reverse are located against each other with a return spring in between; this is to ensure that only one direction can be selected. Range is selected as follows: If the range 2nd/1st solenoid (17) is not activated, regulated pressure is fed through the modulation shift spool and through the 2nd/1st shift spool to the 2nd clutch (38). If the range 2nd/1st solenoid (17) is activated, the pilot pressure will move the shift spool so that 1st clutch (40) is engaged. The range clutches also have modulation which operates as follows: When the range is changed, oil will flow through the modulation shift spool to the chosen range clutch momentary until the friction discs are closed against the dished plate. At that moment the range modulation solenoid (18) is activated. The pilot pressure will move the modulation shift spool so that the oil supply is fed through a restrictor which is in by-pass of the valve. The controlled volume of oil is used to push in the dished outer plate gradually until the clutch is fully closed. This will give a smooth build up of torque. At that moment the range modulation solenoid (18) is released, so that the modulation shift spool returns to its rest position and allows full oil flow to the clutch.

N13–01–13

DRIVETRAIN AND BRAKES The control valve also controls the front lower output disconnect (four-wheel drive) clutch (42). If the disconnect solenoid (19) is activated, the pilot pressure of the disconnect solenoid (19) will move the shift spool so that the disconnect (four-wheel drive) clutch (42) can be fed with full pressure The control valve also has a speed sensor. This sensor will pick up upper output gear speed. This information is used in the electronic gear selector to determine shift logic. Since the sensor picks up upper output gear speed, the signal will be in direct relation to the turbine speed if any directional clutch is engaged.

DRIVETRAIN AND BRAKES DIAGNOSING AND TESTING — POWERSHIFT TRANSMISSION

BHN1301TA

The following information is presented as an aid to isolate and determine the specific problem area in a transmission that is not functioning correctly. When diagnosing a transmission problem, it should be kept in mind that the transmission is only the central unit of a group of related powertrain components. Proper operation of the transmission depends on the condition and correct functioning of the other components of the group. Therefore, to properly diagnose a suspected problem in the transmission, it is necessary to consider the transmission fluid, charging pump, torque converter, transmission assembly, oil cooler, filter, connection lines, and controls, including the engine as a complete system. By analysing the description and operation together with the information in this and the pressure testing section, it should be possible to identify and correct any malfunction which may occur in the system.

Diagnosing Procedures In addition to the mechanical and electrical components, all of which must be in the proper condition and functioning correctly, the correct functioning of the hydraulic circuit is most important. Transmission fluid is the “life blood” of the transmission. It must be supplied in an adequate quantity and delivered to the system at the correct pressures to ensure converter operation, to engage and hold the clutches from slipping, and to cool and lubricate the working components. Faults fall into three general categories: mechanical, hydraulic and electrical. Stall Test Use a stall test to identify whether the transmission, torque converter, or the engine is the malfunctioning component when a complaint of poor performance is made. Transmission Pressure Checks Transmission problems can be isolated by the use of pressure tests. When the stall test indicates slipping clutches, then measure clutch pack pressure to determine if the slippage is due to low pressure or clutch plate friction material failure. In addition, converter charging pressure and transmission lubrication pressure may also be measured.

Mechanical And Electrical Checks Prior to checking any part of the system for hydraulic function (pressure testing), the following mechanical and electrical checks should be made: • Check the parking brake for correct adjustment. • Ensure all lever linkages are properly connected and adjusted in each segment and at all connecting points. • The controls are actuated electrically. Check the wiring and electrical components. • Ensure that all components of the cooling system are in good condition and operating correctly. • The radiator must be clean to maintain the proper cooling and operating temperatures for the engine and transmission. Air clean the radiator, if necessary. • The engine must be operating correctly. Ensure that it is correctly tuned and adjusted to the correct idle and maximum no-load governed speed specifications. Hydraulic Check Note: • The transmission fluid must be at the operating temperatures of 82° to 93°C (180° to 200° F) to achieve correct fluid level and pressure readings.

Caution: Do not attempt to make these checks with cold oil.

Also, before checking the transmission clutches, torque converter, charging pump, and hydraulic circuit for pressure and rate of oil flow, it is important to make the following transmission fluid check: The Check the oil level in the transmission. transmission fluid must be at the correct (full level). All clutches and the converter and its fluid circuit lines must be fully charged (filled) at all times. To raise the oil temperature to this specification it is necessary to either operate (work) the vehicle or run the engine with torque converter at “stall”. (Refer to torque converter stall procedure).

N13–01–19

DRIVETRAIN AND BRAKES Torque Converter Stall Procedure

Caution: If the operating pressures at idle are too low, do not carry out this test. Caution: Do not operate the torque converter at stall condition longer than 30 seconds at one time, shift to neutral for 15 seconds and repeat the procedure until desired temperature is reached. Excessive temperature 120°C (250°F) maximum will cause damage to transmission clutches, fluid, torque converter, and oil seals. Caution: If the engine RPM recorded by the tachometer exceeds the maximum specified RPM, reduce the engine RPM to idle immediately. Clutch slippage is indicated.

Note: • Transmission fluid level and engine coolant level must be correct. Both fluids must be at normal operating temperature Note: The transmission fluid must be at the operating temperature of 82° to 93°C (180° to 200° F) to achieve the correct readings.

Note: • Check the engine is capable of obtaining the specified maximum no-load engine RPM before stall testing.

Caution: Be careful that the vehicle does not move unexpectedly when operating the engine and torque converter at stall RPM.

1. Put the vehicle against a solid barrier, such as a wall, apply the parking brake, service brakes and block the wheels. 2. Start the engine. 3. Put the directional control lever in FORWARD (or REVERSE, as applicable). 4. Select the highest gear and increase the engine speed to the maximum RPM until the tachometer reading stabilizes. 5. Read of the stall speed RPM on the tachometer.

DRIVETRAIN AND BRAKES GENERAL PROCEDURE — CLEANING AND INSPECTION AFTER TRANSMISSION REPAIR After the repaired transmission has been installed in the machine, the oil cooler, and connecting hydraulic system must be thoroughly cleaned. This can be accomplished in several manners and a degree of judgement must be exercised as to the method employed. The following are considered the minimum steps to be taken: 1. Drain the entire system thoroughly. 2. Disconnect and clean all hydraulic lines. Where feasible, hydraulic lines should be removed from the machine for cleaning. 3. Replace oil filter elements cleaning out filter cases thoroughly. 4. The oil cooler must be thoroughly cleaned. The cooler should be “back flushed” with oil and compressed air until all foreign material has been removed. Flushing in direction of normal oil flow

BHN1301GB

will not adequately clean the cooler. If necessary, the cooler assembly should be removed from the machine for cleaning, using oil, compressed air, and steam cleaner for that purpose. DO NOT use flushing compounds for cleaning purposes. 5. Reassemble all components and use only the specified type of oil. Fill the transmission through the filler opening until fluid comes up to the oil level check port. Run the engine for 2 minutes at low RPM to prime the torque converter and hydraulic lines. Check the transmission oil with the engine running at idle RPM and add oil as necessary. Check the transmission oil level when the transmission is at the operating temperature 82 — 93°C (180 — 200°F). 6. Check all drain plugs, lines, connections, etc. for leaks and tighten where necessary.

DRIVETRAIN AND BRAKES GENERAL PROCEDURE — POWERSHIFT TRANSMISSION CLUTCH CALIBRATION

BHN1301GA

The powershift controller can be used to determine the optimal clutch fill parameters. The calibration process creates the ideal start situation for clutch engagement. The clutch fill times can be calibrated in two ways. • Using the Microsoft Windows based T16000 Diagnostic Monitor. The transmission • Stand-alone calibration. controller automatically calibrates the transmission after guiding the user through a set-up procedure. Note: The transmission fluid must be at the normal operating temperature 70 — 120°C (158 — 248°F) to achieve the correct calibration.

Caution: Make sure four-wheel drive is disengaged.

1. Raise the rear of the machine (wheels off the ground) using the stabiliser legs. 2. Set the engine speed to approximately 1500 RPM. Note: • Make sure the transmission output has sufficient resistance to be stalled in neutral, while allowed to spin in either forward or reverse. 3. Lightly apply the parking brake. Note: • During the stand-alone calibration, only the forward and reverse clutches are calibrated. The transmission controller (1) will show the clutch currently being tested and the result of the calibration on the digital display (2). The left side of the display shows the clutch currently being tested. • L for Forward Low • H for Forward High • R for Reverse

2

TV040985

The right side of the display shows the result of the calibration. If the fill time is too short, only the lowest segment is illuminated. If it is too short, but within twice

the tolerance, the middle and lower segments are illuminated.

N13–01–153

DRIVETRAIN AND BRAKES Display Examples (Display)

Description Fill time for the Forward Low clutch is too high.

Fill time for the Forward High clutch is too high, but within twice the tolerance.

Fill time for the reverse clutch was successful and within tolerance. The middle segment is illuminated for 1 second, indicating the successful calibration.

Fill time for the Forward Low clutch is too short, but within twice the tolerance.

Fill time for the Forward Low clutch is too short. Fill time for the Forward Low clutch failed. Three segments of the LCD will be illuminated for 0.5 seconds indicating a problem. The transmissions output was prevented from rotating. This can be caused by braking too hard during the calibration process or a fill time that is excessively high. If the fill time is too high, the calibration system will attempt to reduce the fill time by adapting the fill parameters. The Forward Low clutch calibration phase failed. If the calibration for a specific clutch failed, the original fill time values will be used. This failure can be caused by braking too hard during the calibration process .

N13–01–154

DRIVETRAIN AND BRAKES Stand-Alone Calibration To start the calibration, depress and hold the mode button “M” (1) for 10 seconds (this can be done during or after the key start switch is turned ON). The digital display (2) will show “cA” to indicate the controller has entered the calibration menu.

1

Note: • Make sure the transmission output has sufficient resistance to be stalled in neutral, while allowed to spin in either forward or reverse.

M

When the initial conditions have been carried out, i.e. temperature within range, output speed is zero and the shift lever is in neutral, the transmission controller digital display will alternate between “Go” and “F”(Go to Forward) to indicate Forward has to be selected.

TF 2 TV041062

If the transmission temperature is outside the range for calibration, the temperature will be displayed. The example below shows 85 ºC Temperatures less than 0 ºC are shown as “0.0.” and temperatures greater than 99 ºC are shown as “9.9.” .

When the transmission temperature is within the range for calibration, the transmission controller digital display will alternate between Go and n(GO to Neutral) to indicate Neutral has to be selected.

Note: • To exit the calibration process at any time, move the shift lever to the opposite direction. All original calibration values will be restored. When forward is selected, the transmission calibration starts and completes automatically. Note: • Make sure the transmission controllers power supply is not interrupted during, and 3 seconds after the calibration process has completed. If the power supply is interrupted, re-calibrate the transmission again.

When neutral has been selected, the transmission controller digital display will alternate between “St” and “oP”(STOP) to indicate the parking brake or service brake needs to be lightly applied.

The transmission calibration values are automatically stored in permanent memory after the calibration process has completed. If the calibration of a clutch fails, the controller will default to the factory presets for the clutch.

DRIVETRAIN AND BRAKES The Clutch Circuit Oil from the transmission sump (18) is drawn up through the suction strainer (19) by the transmission oil pump (17). It is forced, under pressure from the transmission oil pump (17), through the transmission full flow oil filter (11) into the clutch circuit. To protect the transmission full flow oil filter (11) during cold start the cold start relief valve (13), dumps oil back to the sump (18) should it exceed 26 bar pressure. From the transmission full flow oil filter (11) the oil flows through the pressure regulator valve (2). This maintains the clutch system pressure at 14 bar. From this valve, oil also enters the torque converter circuit. The solenoid actuated forward / reverse control valve (5), when operated, sends oil from the clutch circuit to the forward or reverse clutch piston which then applies the appropriate clutch. When in neutral the valve closes and oil from the clutch pistons is returned to the sump (18). On four-wheel drive models an additional solenoid valve (9), when engaged, sends oil from the clutch circuit to the four-wheel drive clutch piston which then

applies the clutch. When disengaged the valve (9) closes and oil from the clutch piston is returned to the sump (18).

The Torque Converter Circuit Oil enters the torque converter circuit from the pressure regulator valve (2). It flows through passages in the transmission oil pump housing (17) and into the torque converter (12). Pressure is controlled by the torque converter relief valve (1) which prevents the pressure within the torque converter from exceeding the design limits. Any excess is returned to the sump (18).

The Cooling and Lubrication Circuit Hot oil flows from the torque converter (12) via the inside of the transmission oil pump (17) stator tube, through the centre of the transmission oil pump (17) , and out of the transmission via connecting hoses (15) and (16). It is then passed through an external oil cooler (20) before being returned to the transmission where it is used to cool the clutches and lubricate the input shaft bearings before being returned to the sump (18).

DRIVETRAIN AND BRAKES DIAGNOSING AND TESTING — SYNCHROSHUTTLE TRANSMISSION

BHN1302TA

If a malfunction of the transmission is indicated a systematic pressure checking procedure should be followed. These checks should be carried out while the transmission is still in the vehicle so that true operating conditions are created. Pressure checks are essential since a failure in the transmission hydraulic system may not be easily traceable when the transmission is stripped down on a bench. All pressure checks should be carried out with the transmission gear lever in the neutral position, the oil

temperature at 80 to 85 degrees celcius. and the engine speed maintained at 2000 to 2500 RPM. As a safety precaution the vehicles parking brake should be applied. All pressure test ports have a 9/16 ins. UNF thread. A pressure gauge is required that will measure up to 20 bar ( 290 lb / in2. ). For test port locations refer to PRESSURE TEST PORTS in this section.

The braking system consists of two brake pedals that are independently linked to the brake booster (3). The brake booster contains two pistons that can operate

independently to enable left wheel braking, right wheel braking or all wheel braking. The brake pedals can be linked together with the use of a latching plate.

N13–03–1

DRIVETRAIN AND BRAKES The brake booster uses the same oil as the transmission. The oil is supplied under pressure from the transmission through hose (6) and into the brake booster transmission oil inlet (5), this pressurized oil increases the braking force exerted by the brake booster. The brake booster is also linked directly to the oil reservoir located in the transmission through hose (9) using the brake booster transmission oil reservoir return (4). The pressurized oil is then supplied to the rear left or rear right brake discs (which are housed in the

rear axle) through the brake booster outlets (1) and (2) to the rear axle brake connections. For additional information on the brake components contained in the rear axle, refer to Section N13-04 TWO–WHEEL STEER REAR AXLE or Section N13-05 FOUR-WHEEL STEER AXLE. On machines with four-wheel drive, four-wheel braking is available. With this system no braking components are located in the front axle, instead the braking is achieved using the transmission by engaging four-wheel drive.

The axle described in this manual, consists of a beam casing, housing the differential in the centre and a wheel hub unit at each end. The differential mechanical lock, hydraulically controlled — is supported by two bearings mounted on a suitable structure allowing the bevel gear set to be adjusted. The ring bevel gear is adjusted using two ring nuts located opposite each other. The position of the bevel

pinion, supported by two bearings, is adjusted by installing adjusting shims. The wheel hubs containing the epicyclic reduction gears are supported by two tapered roller bearings. The axle also has a braking system fitted with a hydraulic drive for service braking and mechanical control for the parking brake.

DRIVETRAIN AND BRAKES DIAGNOSING AND TESTING — SYNCHROSHUTTLE TRANSMISSION – CARRARO

Caution: All checks and tests must be performed with the oil at working temperature: 80 °C ±2.

Stall test In order to create ideal conditions for troubleshooting, the converter stall procedure must be performed first. The purpose of this test is to determine whether the torque converter and hydraulic clutch units are operating correctly. This operation will also bring the oil up to its working temperature of 80°C ±2, allowing any problems in the engine, converter or transmission to be identified. Proceed as follows: • Check the oil level. • Activate the parking brake to lock the wheels. • Start the engine and keep it ticking over at idle speed (800 — 1000 [rpm]). • Put the gear lever into 4th. • Put the forward/reverse lever in the FORWARD position. • Increase the engine speed for short periods to a maximum of 1500 — 1700 [rpm], to bring the oil up to working temperature.

• •

Caution: The converter stall test must not exceed a maximum duration of 30 seconds each time. After this 30 second period, put the forward/reverse lever in NEUTRAL for 15 seconds, then repeat the procedure. Failure to keep to these test periods may result in the oil overheating and attendant damage to the clutches, filter, converter and seals.

BHN1306TA

Mechanical problems Check that all of the transmission’s internal and external mechanical parts are correctly fitted (see disassembly and assembly chapters). • Check the efficiency of the parking brake. • Check that the cooling system is in good operating condition. • Check the efficiency of the engine. Make sure that the engine’s idling speed is set correctly and that it complies with the maximum speed specifications under loadless conditions. Hydraulic problems • Check the transmission oil level • Use the specified transmission oil • Check that the hydraulic system is correctly filled. • Check the efficiency of the hydraulic system. Check for oil leaks. • Check the efficiency of the transmission’s hydraulic components (converter, oil pump, filter, connections, hoses). Pressure check Several transmission breakdowns can be identified by running pressure checks. Irregular measurements might indicate that there is a problem. For test port locations refer to PRESSURE TESTING in this section. Electrical problems • Check the efficiency and correct installation of the vehicle battery. • Check the efficiency and correct installation of all electrical components outside the transmission (wiring, cables, alternator, battery, etc.). • Check the efficiency and correct installation of all transmission electrical components (wiring, sensors, solenoid valves, EGM/ECU, etc.)

Gradually reduce the engine speed to minimum. Put the forward/reverse lever in NEUTRAL.

The charging pump draws oil through the suction oil strainer and directs it to the oil filter. Protecting the filter from system pressure in excess of 3.45 Bar (50 PSI) is a by-pass valve . A pressure regulating valve maintains the pressure for the control valve and clutches at 18.5 bar (268 PSI) and excess oil is returned to the torque converter circuit. The torque converter is protected from pressures over 5.5 bar (80 PSI) by a safety valve located internally in the charge pump. After leaving the torque converter, the oil flows through the oil cooler then on to lubricate and cool the transmission bearings and clutches. The oil drains back to the transmission sump under gravity. The transmission is composed of five main assemblies. 1

DRIVETRAIN AND BRAKES Engine power is transmitted from the engine flywheel to the impeller through the impeller cover. This element is the charging portion of the hydraulic torque converter and is the primary component which starts the oil flowing to the other components with the torque converter which results in torque multiplication. The impeller can be compared to a centrifugal pump in that it picks up fluid at its centre and discharges at its outer diameter. The torque converter turbine is mounted opposite the to impeller and is connected to the turbine shaft or directional clutch shaft. This element receives fluid at its outer diameter and discharges at its centre. The stator of the torque converter is located between the impeller and turbine elements, at the centre of there diameters. Its function is to take the fluid which is exhausting from the inner portion of the turbine and change its direction to allow correct entry for recirculation into the impeller element. This recirculation will make the converter multiply torque. The stator can also freewheel when the impeller and turbine RPM are similar to each other allowing a fluid

coupling operation in order to achieve a high speed on the road. This in turn means less heat is generated and fuel consumption is reduced. The torque converter will multiply engine torque to its designed maximum multiplication ratio when the turbine shaft is at zero RPM (stall). Therefore we can say that as the turbine shaft is decreasing in speed, the torque multiplication is increasing. In the impeller cover a splined shaft is installed which runs inside the turbine shaft to drive a hydraulic pump which is fitted at the back of the transmission. Since the shaft is connected to the centre of the impeller cover, the hydraulic pump speed will be the same as engine speed. The rear side of the impeller cover has a tanged drive which drives the transmission charging pump located in the converter housing. The transmission charging pump speed is also the same as the engine speed and provides fluid under pressure to allow engagement of the various clutches.

DRIVETRAIN AND BRAKES The turbine shaft driven from the turbine transmits power to the forward or reverse clutches. These clutches consist of a drum with splines and a bore to receive a hydraulic actuated piston. The piston is oil tight by the use of sealing rings, also these pistons have drain orifices for a quick release when the clutch is being disengaged. A steel disc with external splines is inserted into the drum and rests against the piston. Next, a friction disc with teeth at the internal diameter is inserted. Discs are alternated until the required total is achieved. A backing plate is then inserted and secured with a snap ring. A hub with outer diameter teeth is inserted into the discs with teeth on the inner diameter. The discs and hub are free to increase in speed or rotate in the opposite direction as long as no pressure is present in that specific clutch. To engage the clutch, the control valve which is fitted on the top of the transmission will direct oil under pressure through tubes and passages to the selected clutch shafts. Oil seals are located on the clutch shafts. These rings direct the oil through a drilled passage in the shaft to the desired clutch.

Pressure of the oil forces the piston and discs against the backing plate. The discs with splines on the outer diameter clamping against discs with teeth on the inner diameter enables the drum and hub to be locked together and allows them to drive as one unit. When the clutch is released, a return spring will push the piston back and oil will drain back via the control valve into the transmission sump. The powershift transmission has one reverse clutch and one forward clutch. This, in combination with the four range clutches, results in the transmission having 4 forward speeds and 3 reverse speeds. The engagement of the directional clutches is modulated; which means that clutch pressure is built up gradually. This will enable the unit to make forward, reverse shifts while the vehicle is still moving and will allow smooth engagement of drive. The forward and reverse clutches are modulated by the Trax software. The modulation of the gear clutches is controlled by a ramp valve in the control valve. The 4WD clutch and differential lock are not modulated

N13–07–8

DRIVETRAIN AND BRAKES 3. The Range Clutches

Once a directional clutch is engaged, power is transmitted to the range clutches. Operation and actuation of the range clutches is similar to the directional clutches. The engagement of the range clutches is also modulated to enable a smooth engagement.

The modulation for these clutches is achieved by means of a ramp valve fitted in the control valve. This is controlled manually by a spring and which limits oil flow to the clutch during gear changes.

N13–07–9

DRIVETRAIN AND BRAKES 4. The Output Section

With a range clutch engaged power is finally transmitted to the output shafts. The powershift transmission has a upper output at the rear of the transmission , and a lower output at the front side. Output rotation of the rear upper output is the same engine rotation when the forward clutch is engaged, while output rotation of the front output is the opposite as the engine rotation with the forward clutch engaged.

The lower front output has a four wheel drive clutch to enable four-wheel drive / two wheel drive to be selected. The clutch is similar to the other clutches. The four wheel drive clutch is controlled electrically. The clutch is engaged with an electrical signal through a solenoid located in the transmission control valve.

N13–07–10

DRIVETRAIN AND BRAKES 5. The Transmission Controls

Transmission EGM / ECU located under floor RHS

Transmission control valve

Operation of the transmission control valve is as follows: (Refer to transmission hydraulic circuit) The control valve has 8 solenoids, and a ramp valve. Regulated pressure between 14 bar — 18.5 bar dependent on the engine RPM is directed to the control valve. In the control valve the pressure is then directed to the solenoid activated spool valves. When a gear is selected a solenoid for the relevant gear is activated this lifts a spool valve allowing fluid into the clutch activating the gear. As the gear is activated, the ramp valve will give a smooth progressive engagement of the gear. When forward is selected the forward proportional solenoid is activated. When reverse is selected the reverse proportional solenoid is activated. The power flow goes through a reverse idler changing the rotation of the transmission. The smooth engagement of the forward and reverse clutches is controlled by the Trax software. Range is selected as follows: When the 1st speed solenoid is activated this will shift the spool engaging the 1st speed clutch.

As each speed is selected the previous speed clutch disengages. The clutches also have modulation which operates as follows: When the range is changed, oil will flow through the ramp valve to the chosen range clutch engaging the clutch in a progressive manner. This protects the transmission from harsh gear changes and excessive strain on the transmission. The control valve also controls the front lower output (four-wheel drive) clutch. If the solenoid is activated this will shift the spool engaging the (four-wheel drive) clutch. The ECU has an input from a speed sensor. The sensor measures the speed of the rear output shaft. This information is used in the electronic gear selector to determine shift logic. Since the sensor picks up output gear speed, the signal will be in direct relation to the turbine speed if any directional clutch is engaged.

DRIVETRAIN AND BRAKES DIAGNOSING AND TESTING — CARRARO POWERSHIFT TRANSMISSION The following information is presented as an aid to isolate and determine the specific problem area in a transmission that is not functioning correctly. When diagnosing a transmission problem, it should be kept in mind that the transmission is only the central unit of a group of related powertrain components. Proper operation of the transmission depends on the condition and correct functioning of the other components of the group. Therefore, to properly diagnose a suspected problem in the transmission, it is necessary to consider the transmission fluid, charging pump, torque converter, transmission assembly, oil cooler, filter, connection lines, and controls, including the engine as a complete system. By analysing the description and operation together with the information in this section and the pressure testing section, it should be possible to identify and correct any malfunction which may occur in the system.

Diagnosing Procedures In addition to the mechanical and electrical components, all of which must be in the proper condition and functioning correctly, the correct functioning of the hydraulic circuit is most important. Transmission fluid is the “life blood” of the transmission. It must be supplied in an adequate quantity and delivered to the system at the correct pressures to ensure converter operation, to engage and hold the clutches from slipping and to cool and lubricate the working components. Faults fall into three general categories: mechanical, hydraulic and electrical. Stall Test Use a stall test to identify whether the transmission, torque converter, or the engine is the malfunctioning component when a complaint of poor performance is made. Transmission Pressure Checks Transmission problems can be isolated by the use of pressure tests. When the stall test indicates slipping clutches, then measure clutch pack pressure to determine if the slippage is due to low pressure or clutch plate friction material failure. In addition, converter charging pressure and transmission lubrication pressure may also be measured.

BHN1307TA

Mechanical And Electrical Checks Prior to checking any part of the system for hydraulic function (pressure testing), the following mechanical and electrical checks should be made: • Check the parking brake for correct adjustment. • Ensure all lever linkages are properly connected and adjusted in each segment and at all connecting points. • The controls are actuated electrically. Check the wiring and electrical components. • Ensure that all components of the cooling system are in good condition and operating correctly. • The radiator must be clean to maintain the proper operating temperatures for the engine and transmission. Clean the radiator, if necessary using compressed air. • The engine must be operating correctly. Ensure that it is correctly tuned and adjusted to the correct idle and maximum no-load governed speed specifications. Hydraulic Check Note: • The transmission fluid must be at the operating temperatures of 80° C (180° F) to achieve correct fluid level and pressure readings.

Caution: Do not attempt to make these checks with cold oil.

Also, before checking the transmission clutches, torque converter, charging pump, and hydraulic circuit for pressure and rate of oil flow, it is important to make the following transmission fluid check: The Check the oil level in the transmission. transmission fluid must be at the correct (full level). All clutches and the converter and its fluid circuit lines must be fully charged (filled) at all times. To raise the oil temperature to this specification it is necessary to either operate (work) the vehicle or run the engine with torque converter at “stall”. (Refer to torque converter stall procedure).

N13–07–19

DRIVETRAIN AND BRAKES Torque Converter Stall Procedure

Caution: If the operating pressures at idle are too low, do not carry out this test. Caution: Do not operate the torque converter at stall condition longer than 30 seconds at one time, shift to neutral for 15 seconds and repeat the procedure until desired temperature is reached. Excessive temperature 120°C (250°F) maximum will cause damage to transmission clutches, fluid, torque converter, and oil seals. Caution: If the engine RPM recorded by the tachometer exceeds the maximum specified RPM, reduce the engine RPM to idle immediately. Clutch slippage is indicated.

Note: • Transmission fluid level and engine coolant level must be correct. Both fluids must be at normal operating temperature Note: • The transmission fluid must be at the operating temperature of 80° C (180° F) to achieve the correct readings. Note: Check the engine is capable of obtaining the specified maximum no-load engine RPM before stall testing.

Caution: Be careful that the vehicle does not move unexpectedly when operating the engine and torque converter at stall RPM.

1. Put the vehicle against a solid barrier, such as a wall, apply the parking brake, service brakes and block the wheels. 2. Start the engine. 3. Select the highest gear and increase the engine speed to the maximum RPM until the tachometer reading stabilizes. 4. Put the directional control lever in FORWARD (or REVERSE, as applicable). 5. Read the stall speed RPM on the tachometer.

DRIVETRAIN AND BRAKES GENERAL PROCEDURE — CARRARO POWERSHIFT CLEANING AND INSPECTION AFTER TRANSMISSION REPAIR After the repaired transmission has been installed in the machine, the oil cooler, and connecting hydraulic system must be thoroughly cleaned. This can be accomplished in several manners and a degree of judgement must be exercised as to the method employed. The following are considered the minimum steps to be taken: 1. Drain the entire system thoroughly. 2. Disconnect and clean all hydraulic lines. Where feasible, hydraulic lines should be removed from the machine for cleaning. 3. Replace oil filter elements cleaning out filter cases thoroughly. 4. The oil cooler must be thoroughly cleaned. The cooler should be “back flushed” with oil and compressed air until all foreign material has been removed. Flushing in direction of normal oil flow

BHN1307GB

will not adequately clean the cooler. If necessary, the cooler assembly should be removed from the machine for cleaning, using oil, compressed air, and steam cleaner for that purpose. DO NOT use flushing compounds for cleaning purposes. 5. Reassemble all components and use only the specified type of oil. Fill the transmission through the filler opening until fluid comes up to the oil level check port. Run the engine for 2 minutes at low RPM to prime the torque converter and hydraulic lines. Check the transmission oil with the engine running at idle RPM and add oil as necessary. Check the transmission oil level when the transmission is at the operating temperature 80 °C (176°F). 6. Check all drain plugs, lines, connections, etc. for leaks and tighten where necessary.
