GENERAL SAFETY

PREPARATION FOR EMERGENCIES  Know where fire extinguishers are located and how to use them.  Keep a first aid kit and an eye wash kit near the work area.  Obtain emergency phone numbers for doctors, ambulance service, hospital and fire department

HANDLE FLUIDS SAFELY AND AVOID FIRE  

Handle fuel with care. It is highly flammable Do not smoke when refueling and beware of open fire or sparks from refueling area. Engine must be stopped when refueling and Refuel in open and well ventilated area.  Store flammable fluids away from fire hazards.  It is dangerous to puncture or throw the pressurized containers in fire.

DISPOSE OF FLUIDS PROPERLY  Improperly disposing of fluids is harmful for environment and ecology. Before draining any fluids, find out the proper way to dispose of waste from your local environmental agency.  Collect draining fuel, oil or other fluids in Suitable containers. Do not use food or beverage containers, that may mislead someone to drink from them. Clean the oil spillage at once.  Do not pour oil into the ground, sewer system, stream of the river, pond or lake. Observe the environmental protection regulations when disposing of oil fuel, coolant, brake fluid, filters, batteries and other harmful waste.

GENERAL SAFETY

ELECTRICAL SYSTEM

 Before welding on the machine or repairing the electrical system, ALWAYS turn the master switch OFF. Disconnect the negative ( — ) terminal of the battery.  Be careful not to break or damage wiring, when dismounting or removing components. Damaged wires can cause short-circuit spark and fire.  Wear safety glasses when working with the batteries.  The sulfuric acid of the electrolyte is poisonous and harmful. If it is splashed, immediately flush with plenty of water.  If splashed into eye, wash your eyes with plenty of water and get medical first aid.  To inhale the electrolyte vapor is harmful for your lungs.  Because of explosion risk, keep away sparks, open flame from top of the battery. 

Wear a safety mask not to inhale the vapor.

 If the terminals are short-circuited with a metal object, the battery may explode. Do not put any metal object or wire on the battery.  It is important to tighten the battery terminals properly. Otherwise, because of insufficient contact, there will be a contact resistance and heat will be generates on the terminals. The lead terminal abrasion will occur.  Be careful with the polarity when connecting the battery terminals.  Do not wash the sensors, connectors and instruments in the cab with water or steam. Dampness in the electrical system can cause abnormal operation and failure.

00

HMK 102 ENERGY WORKSHOP MANUAL

03 GENERAL SAFETY CAUTIONS DURING REPAIRS  When dismounting any cover or cap under spring tension or system pressure, be careful with removing the bolts. Two bolts on opposite sides must be removed after the spring tension or pressure is released.  High pressure grease in the recoil spring adjusting system can eject and cause injury. Do not loosen the grease valve more then 1 turn, before the grease pressure is released in the system.

 When assembling and disassembling parts, always use specified tightening torques.  Installing protective guards, cage, etc. is very important. The rotation part’s guards must be installed and tighten correctly.  Be careful not to let your clothes or hair loose to be caught by rotating parts.  Never touch or try to hold rotating parts such as fan blades or fan belts. 

Never insert your finger or hand to align two holes.

 Be careful not to pinch your fingers in a hole, between parts or tools.

WORKSHOP MANUAL

02 ENGINE WORKSHOP GENERAL INFORMATION INTRODUCTION This Workshop Manual has been written to provide assistance in the service and overhaul of Perkins 1100 series 4 cylinder engines. It should be used in conjunction with normal workshop practice and information contained in current service bulletins. Mention of certain accepted practices therefore, has been purposely omitted in order to avoid repetition. For overhaul procedures the assumption is made that the engine is removed from the application. The engine conforms with USA (EPA/CARB) stage 2 and EEC stage 2 emissions legislation for agriculture, construction and industrial applications. When reference is made to the “left” or “right” side of the engine, this is as seen from the flywheel end of the engine. “SAFETY PRECAUTIONS” are given for your protection and must be used all times. Danger is inbdicated in the text by two methods: Warning ! This indicates that there is a possible danger to the person. Caution : This indicates that there is a possible danger to the engine. Note : Is used where the information is important, but there is no a danger. In this Workshop Manual, the Perkins 1100 series RG model turbocharged 4 cylinders engine workshop procedures are explained. The correct identification of the engine is by the full engine number. The engine number is stamped on a label which is fastened to the left side of the cylinder block. If you need parts, service or information for your engine, you must give the complete engine number to the HİDROMEK ‘s After Sales Dealers and Service.

The engine serial number plate contains the following information: (1) TPL number (2) Type (3) Serial number (4) List number

2 SAFETY PRECAUTIONS

These safety precautions are important. You must refer also to the local regulations in the country of use. Some items only refer to specific applications.  Only use these engines in the type of application for which they have been designed.  Do not change the specification of the engine.  Do not smoke when you fill the fuel tank.  Clean away fuel which has been spilt. Material which has been contaminated by fuel must be moved to a safe place.  Do not refill the fuel tank while the engine runs (unless it is absolutely necessary).  Do not clean, add lubricating oil, or adjust the engine while it runs (unless you have had the correct training; even then extreme care must be used to prevent injury).  Do not make adjustments that you do not understand.  Ensure that the engine does not run in a location where it can cause a concentration of toxic emmisisons.  Other persons must be kept at a safe distance while the engine or auxiliary equipment is in operation.  Do not permit loose clothing or long hair near moving parts.  Keep away from moving parts during engine operation. Warning! Some moving parts cannot be seen clearly while the engine runs.  Do not operate the engine if a safety guard has been removed.  Do not remove the filler cap, or any component of the cooling system while the engine is hot and while the coolant is under pressure because dangerous hot coolant can be discharged.  Do not allow sparks or fire near the batteries (especially when the batteries are on charge) because the gases from the electrolyte are highly flammable. The battery fluid is dangerous to the skin and especially to the eyes.  Disconnect the battery terminals before a repair is made to the electrical system.  Only one person must control the engine.  Ensure that the engine is operated only from the control panel or from the operator’s position.  If your skin comes into contact with high pressure fuel, obtain medical assistance immediately.  Diesel fuel and lubricating oil (especially used lubricating oil) can damage the skin of certain persons. Protect your hands with gloves or a special solution to protect the skin.  The combustible material of some components of the engine (for example certain seals) can become extremely dangerous if it is burned. Never allow this burnt material to come into contact with the skin or with the eyes.  Do not wear clothing which is contaminated by lubricating oil. Do not put material which is contaminated with oil into the pockets of clothings.  Discard used lubricating oil in a safe place to prevent contamination.

WORKSHOP MANUAL

02 ENGINE WORKSHOP SAFETY PRECAUTIONS (cont’d)   

   

Ensure that the control lever of the transmission drive is in the “out-of-drive” position before the engine is started. Use extreme care if emergency repairs must be made in adverse conditions. Always use a safety cage to protect the operator when a component is to be pressure tested in a container of water. Fit safety wires to secure the plugs which seal the hose connections of a component which is to be pressure tested. Do not allow compressed air to contact your skin. If compressed air enters your skin, obtain medical help immediately. Turbochargers operate at high speed and at high temperatures. Keep fingers, tools and items away from the inlet and outlet ports of the turbocharger and prevent contact with hot surfaces. Do not clean an engine while it runs. If cold cleaning fluids are applied to a hot engine, certain components on the engine may be damaged. Fit only genuine Perkins parts from your HİDROMEK dealer.

ENGINE LIFT EQUIPMENT The maximum weight of the engine without coolant, lubricant, or a gear box fitted will vary for different applications. It is recommended that lift equipment of minimum capacity is used: 600 kg (1320 lbs) Note: Use lift equipment or obtain assistance to lift heavy engine components. Before the engine is lifted:  Always use lift equipment of the approved type and correct capacity to lift the engine. It is recommended that lift equipment of the type shown in the figure is used, to provide a vertical lift directly above the engine lift brackets (1). Never use a single lift bracket to raise an engine.  Check the engine lift brackets for damage and that they are secure before the engine is lifted. The torque for the setscrews for the engine lift brackets is 44 Nm (33 lbf.ft) 4,5 kgf m.  To prevent damage to the rocker cover, ensure that there is clearance between the hooks and the rocker cover.

4 VITON SEALS

Some seals used in engines, and in components fitted to engines, are made of Viton. Viton is used by many manufacturers and is a safe material under normal conditions of operation. If Viton is burned, a product of this burnt material is an acid which is extremely dangerous. Never allow this burnt material to come into contact with the skin or with the eyes. If it is necessary to come into contact with components which have been burnt, ensure that the precautions which follow are used:  Ensure that the components have cooled.  Use neoprene gloves and discard the gloves safely after use.  Wash the area with the calcium hydroxide solution and then with clean water.  Disposal of components and gloves which are contaminated must be in accordance with local regulations. If there is contamination of the skin or eyes, wash the affected area with a contunious supply of clean water or with calcium hydroxide solution for 15 — 60 minutes. Obtain immediate medical attention.

SAFETY CAUTIONS WHEN AN ENGINE IS CLEANED Care should be taken, when an engine is cleaned with a high pressure cleaning system. Cautions:  Do not wash an engine while it runs or while it is hot. If cold cleaning fluids are applied to a hot engine, certain components on the engine could be damaged.  Leave the engine to cool for at least one hour and disconnect the battery connections before cleaning.  Do not wash any part of the fuel injection pump, cold starty device, electrical shut off solenoid or electrical connectors.  Ensure that the alternator, starter motor and any other electrical components are shilded and not directly cleaned by the high pressure cleaning system. If these cautions are ignored, the engine or certain components could be damaged, fail to operate and also make the manufacturer’s warranty invalid.

CRANKSHAFT OVERHAUL Notes:  Nitrocarburized crankshafts must be hardened again, each time they are machined. These crankshafts must be nitrocarburized or, if this process is not available, they can be nitrided for 20 hours. If neither process is available a new crankshaft, or a “new for old” crankshaft must be fitted.  Check the crankshaft for cracks before and after it is ground. Demagnetize the crankshaft after it has been checked for cracks.  After the crankshaft has been machined remove any sharp corners from the lubricating oil holes.  Surface finish and fillet radii must be maintained and require Ra 0,4 µm.

THREAD SEALANT When setscrews or studs are fitted into holes which are tapped through the cylinder block, a suitable sealant must be used to prevent leakage. Micro encapsulated anaerobic sealant (M.E.A.S.) fasteners have been introduced instead of jointing compounds or other sealants when the fasteners are fitted in through holes into oil or coolant passages. The identification of these fasteners, as supplied, is by a red, blue, or other colour sealant around the fastener threads. With M.E.A.S. sealed studs, the sealed end must be fitted into the cylinder head/ cylinder block etc. Ensure that the threaded holes have a 1,59 mm (0.0625 in) 45 0 chamfer, to ensure that when the new fasteners are fitted the M.E.A.S. sealant is not removed. If the fasteners have to be removed and fitted again, the threads must be cleaned and a suitable sealant used. Note: New setscrews have sealant applied by the manufacturer to the first 13,0 mm (0.50 in) of the threads. If the setscrews are to be used again, clean the old sealant from the male and female threads and apply new sealant to the setscrews.

COMPRESSION TEST DATA Tests have shown that many factors affected compression pressures. Battery and starter motor condition, ambient conditions and the type of gauge used can give a wide variation of results for a given engine. It is not possible to give accurate data for compression pressure, but tests have shown that the results should be within 2000/3500 kPa, (300/500 lbf/in 2), 21,0/35,0 kgf/cm2 for diesel engines. Compression tests should only be used to compare between the cylinders of an engine. If one or more cylinders vary by more then 350 kPa, (50 lbf/ in 2), 3,5 kgf/cm2 then those cylinders may be faulty. Compression tests should not be the only method used to show the condition of an engine, but they should be used together with other symptoms and tests.

How to do a compression test Caution: Before the compression test, ensure that the battery is in good condition and that it is fully charged. Also ensure that the starter motor is in good condition. 1. Ensure that the valve tip clearances are set correctly 2. Remove the atomizers

3. Fit a suitable gauge into the atomizer hole of the cylinder to be tested. Warning: ensure that the engine can not start. 4. Operate the starter motor and record the pressure indicated on the gauge for each cylinder.

28 CYLINDER HEAD ASSEMBLY General description

In a diesel engine there is little carbon deposit and for this reason th number of hours run is no indication of when to overhaul a cylinder head assembly. The factors which indicate when an overhaul is necessary are how easily the engine starts and its general performance. The cast iron cylinder head is fastened to the cylinder block by flanged head setscrews. The cylinder head gasket is a multi-layer contruction. The individual inlet and exhaust ports are designed to assist air swirl and improve air flow. The intake manifold is integral within the cylinder head, and the rocker cover also contains the engine breather pipe. The cylinder head assembly has two overhead valves fitted for each cylinder. Each overhead valve is held in place by a single coil spring, cap, and two collets. The face angle of the intake and the exhaust valves are both 300. The valves move in sintered steel valve guides which can also be renewed. The exhaust valve guides have a counterbore to prevent seizure of the valve stem caused by a build up of carbon under the head of the valve. Each valve stem is fitted with a synthetic rubber oil seal. The overhead valves are operated by a rocker shaft assembly fitted to the top of the cylinder head and under a composite rocker cover. The forged steel rocker levers are operated by cold drawn push rods with hardened heads. The rocker shaft is secured to the cylinder head by sintered steel brackets between each pair of valves. The rockers and valve gear are lubricated by an oil flow from the hollow rocker shaft that receives a reduced oil flow from the cam shaft oil feed. Tappet adjustment is achieved by adjustment screws and locknuts at the push rod end of each rocker lever.

VALVE GUIDES To inspect To check the valve guides for wear. The maximum permissible clearance (5) with a valve lift of 15,0 mm (0.6 in), between the valve stem and the bore of the guide is 0,22 mm (0.009 in) for intake valves, and 0,25 mm (0.010 in) for exhaust valves. If the clearance, with a new valve fitted, is more than the limit, than a new valve guide (4) must be fitted. It is recommended that the procedure given below is used to check the valve guide clearance: 1. Put a new valve in the valve guide. 2. Put a dial test indicator with a magnetic base (1) onto the face of the cylinder head. 3. With the valve lifted 15,0 mm ( 0.6 in) and the gauge (2) in contact with the edge of the level head (3), move the valve radially away from the gauge. With the valve held in this position, set the gauge to zero. 4. Move the valve radially across the axis of the cylinder head towards the gauge. Make a note of the reading on the gauge. If the reading is equal to or greater than the data given above, a new valve guide (4) must be fitted. To remove Special tools Remover / replacer for valve guides

WORKSHOP To inspect and to correct (cont’d) Note: The partially finished valve guides are reamed and the valve seats are cut in one operation with a special tool. The valve seat and the guide are cut in one operation to ensure the concentricity of the valve seat to the valve guide. This will ensure a good seal between the guide and its seat. New valves and new valve seat inserts must be fitted each time a new valve guide is fitted. Valves must not be lapped. If all or most of the original valve guides need to be renewed it may be cost effective to overhaul or exchange the cylinder head. 1. Before any work is done on the valve seats, new valve guides must be fitted. Cautions:  Ensure that the correct cutter is fitted, for 300 valve seats.  Ensure that the valve seat cutter is not allowed to fall onto the seat as this can damage the blades. Note: The intake valve has a larger diameter head than the exhaust valve. 2. Select the relevant valve seat cutter, 300 (2) and the valve guide reamer (1). Set the blades of the cutters to the diameter of the valve seat to be cut. (see “Intake & exhaust valves”) Note: The blades of the reamer must not cut the valve guide when the seat is cut. 3. Fit the cutter onto the reamer and push the handle fully onto the reamer. Ensure that the flat part of the reamer shank is towards the allen screw. Tighten the allen screw to secure the reamer to the handle. 4. Fit the reamer / cutter assembly into the valve guide. Ensurethat the valve seat cutter is not allowed to fall onto the seat as this can damage the blades. Carefully turn the handle in a clockwise direction (3) and gradually move the reamer into the valve guide until the valve guide is reamed to the finished size. A lubricant is not necessary. 5.

50 PISTON AND CONNECTING ROD ASSEMBLIES

General description The pistons that are used in the engine have a combustion chamber in the top of the piston. The combustion chamber is designed to give an efficient mix of fuel and air. The pistons and connecting rods are matched to the relevant cylinder. The pistons have two compression rings and an oil control ring. The groove for the top ring has a hard metal insert to reduce wear of the groove. The piston skirt has a layer of graphite to improve the wear characteristics. Axial location of the fully floating gudgeon pin is by circlips. The gudgeon pin is off-centre to reduce the noise level. Piston cooling jets are fitted in the cylinder block to spray lubricating oil onto the inner surface of the pistons. The correct piston height is important to ensure that the piston does not contact the cylinder head and to ensure the efficient combustion of fuel. The piston height is controlled by the length of the connecting rod. There are six length grades of connecting rods used to obtain the correct piston height. To obtain the different grades, the small-end bush is machined off-centre. The amount that the bush is off-centre gives the different length grades. In service, a partially finished small-end bush is available, which can be fitted to the original connecting rod and machined to obtain the correct length grade. Specialist equipment and personnel with the correct training are neede to machine the partially finished small-end bush. Connecting rod kits are also available with the small end bush fitted and machined to obtain the correct connecting rod grade. Notes:  If the crankshaft of the cylinder block is to be renewed, it may be necessary to change the grade of the connecting rods. This will occur if the correct piston height above the cylinder block face cannot be maintained with the original connecting rod assemblies.  Always use the engine identification number to order new parts. The connecting rod is a one-piece forging that is fractured hydraulically to split the big end cap from the connecting rod. This process produces rough but accurately matched surfaces (1).

A partially finished small end bush, which can be fitted to the original connecting rod and machined to obtain the correct length grade is available. Specialist equipment and personnel with the correct training are needed to machine the partially finished small end bush. Connecting rod kits are also available with the small end bush fitted and machined to obtain the correct connecting rod grade. Cautions:  It is important that the piston does not contact the cylinder head. Ensure that the piston height above the cylinder block is correct.  Ensure that the connecting rods are fitted in the correct cylinder. Record the position of the connecting rod and its relevant cylinder when it is removed from the engine. To ensure that the piston height above the cylinder block is correct, the engine may have up to six length grades (F to L) of connectin rods fitted. Identification of the length grade is by a letter or color which is marked on the side of each connecting rod (1). The letter F is the longest grade of connecting rod and letter L is the shortest grade. The difference between grades is 0,046 mm (0.0018 in). The dimensions for each grade are listed below: Grade letter F G H J K L

Color code Red Orange White Green Purple Blue

Length (mm) 165,728 / 165,761 165,682 / 165,715 165,637 / 165,670 165,591 / 165,624 165,545 / 165,578 165,499 / 165,532

If the grade letter or coulor on the side of the connecting rod cannot be seen, the length can be checked by the measurement of the dimension (X).

The end-float can be checked with a feeler gauge between a thrust washer and the crankshaft or wit a dial test indicator on one end of the crankshaft to check the movement.

If the end-float is more than the tolerance given in the relevant data and dimensions for the “Crankshaft”, thrust washerswhich are 0,019 mm (0.0075 in) oversize can be fitted. The oversize thrust washers can be fitted to one or to both sides of the main bearing. They are fitted instead of the standard size washer, to reduce the end-float to the factory tolerances.

82 TIMING CASE AND DRIVE ASSEMBLY General description The timing case is made of either aluminium or cast iron. The cast iron timing case is used to mount two power take-off units.

The timing gears are made of steel. There are two different types of steel camshaft gear and upper idler gear. One is for heavy duty and one for light duty. A power take-off is available on either the left hand side or the right hand side or on both sides of the timing case. Some engines have an idler gear with a roller bearing. The drive from the crankshaft gear passes through an idler gear to the camshaft gear and to the gear of the fuel injection pump. The drive from the crankshaft gear also passes a lower idler gear to the gear of the lubricating oil pump. The coolant pump isdriven by the gear of the fuel injection pump. The camshaft and the fuel injection pump run at half the speed of the crankshaft. The timing case contains the front oil seal. To remove Notes:  To assist with access to the timing case cover, the fan drive can be removed.  The timing case cover can be removed with the crankshaft pulley fitted.

1. Remove the coolant pump.

ENGINE WORKSHOP CYLINDER BLOCK ASSEMBLY General description The cylinder block is made of high duty cast iron with an integral crankcase. The sides of the cylinder block extend below the crankshaft center line to give added strength. The cylinder block provides full length support for the cylinder bores. All bores are honed with silicon carbide tools to a controlled finish to ensure long life and low oil consumption. A bush is fitted in the cylinder block for the front camshaft journal and the other camshaft journals run directly in the block. To dismantle Notes:  If the cylinder block is to be renewed, it may be necessary to change the grade of the connecting rods. This will occur if the correct piston height above the block face cannot be maintained with the original piston and connecting rod assemblies.  All of the components that need to be removed for access to the cylinder block are referred to in the procedure below. As a result some of the stages within operations may be repeated. 1. Ensure that all engine fluids are drained. 2. Remove the the wiring harness, and the speed and timing sensor. 3. Remove the VLPM. 4. Remove the lubricating oil cooler. 5. Remove the lubricating oil filter head. 6. Remove the cylinder head. 7. Remove the crankshaft. 8.

CYLINDER BORE To inspect To ensure the best performance during the life of the engine it is important that worn or damaged cylinder bores are re-bored and re-honed. The condition of a cylinder bore is decided by:  The amount and location of any polished areas  Wear  Damage to the bore wall Note: It will not be necessary to re-bore / re-hone if:  

The honed finish can still be clearly seen. The engine performance and oil consumption are acceptable.

To check the condition of a cylinder bore 1. Inspect the bore surface for cracks and deep scratches. 2. Check the bore wall for areas where the honed finish has been polished away. Check especially the area around the top of the bore just below the carbon ring. In this area, thrust from the top piston ring is at its maximum.

Cautions:    

Do not use “Flex-hone” to repair cylinder bores. New oversized piston and rings must be fitted when the cylinder bore is re-bored / re-honed. An engine can have high oil consumption with very little wear of the bores, if the surfaces of the bores are glazed. Specialist training and equipment are needed to machine the finish of a cylinder bore.

ENGINE WORKSHOP ENGINE TIMING General description To ensure that 1100 series 4 cylinder engines have an accurate system of timing, the engines are pin timed. This system will set the engine so that number 1 piston is at top dead center (TDC) on the compression stroke. To reach the accurate fuel injection needed for engines to conform to emission legislation, the latest fuel injection pumps operate at a static timing of TDC. It is important that fuel injection timing is accurate to conform to emission legislation. Always use operation to obtain TDC on the compression stroke of number 1 cylinder. Cautions:  The hub nut (1) must not be released until TDC on the compression stroke is set, the backlash is removed from the fuel injection pump gear and the fuel pump shaft is locked. If the nut (1) is loosened before TDC on the compression stroke is set and the fuel pump shaft is locked the fuel pump timing will be lost. The pump will have to be removed and sent to be reset.

To set number 1 piston to TDC on the compression stroke Special tools Crankshaft timing pin

Part No: 27610211

Camshaft timing pin

Part No: 27610212

Cautions:  This procedure must only be carried out by a person with the correct training.  The timing pins are a push fit. Do not use excessive force to fit the pins.  Do not use the pins as a locking device when repairs are carried out on the engine.  The timing pins must be removed before the timing case cover is fitted. Failure to do so will damage the engine.

ENGINE WORKSHOP ASPIRATION SYSTEM General description Warning! Turbochargers operate at high speed and high temperatures. Keep fingers, tools and debris away from the inlet and outlet ports of the turbocharger and prevent contact with hot surfaces. The turbocharger is fitted between the exhaust and intake manifold and is driven by exhaust gas. The turbocharger passes air to the engine at more than atmospheric pressure. It is lubricated by oil from the main gallery. The oil enters through the bearing housing of theturbocharger and returns to the cylinder block. From there it is returned to the lubricating oil sump.

All turbochargers that are fitted with a waste-gate unit (1), which is controlled by boost pressure from the inlet manifold, will allow some of the exhaust gases to by-pass the turbine rotor at higher engine speeds. With this arrangement the turbocharger can be designed to be more effective at lower engine speeds.

ENGINE WORKSHOP LUBRICATION SYSTEM General description Pressure lubrication is supplied by a rotor type pump which is driven through an idler gear from the crankshaft gear. The pump has an inner rotor and outer rotor which are off-set to each other. There is an interference fit between the inner rotor and the drive shaft. When the pump rotates because the space between the lobes which are in mesh, increases to cause a suction to fill the space and a decrease to create a pressure increase. Lubricating oil from the sump passes through a strainer and pipe into the suction side of the pump. The pump delivers the oil to the cylinder block via oil cooler. The oil is transferred by the oil pump frame to the oil filter passage in the cylinder block. Then relief valve is integral with the pump and re-circulates the excess oil directly back to oil pump inlet. The lubricating oil passes through the oil filter and directly back to the mainpressure rail which drilled the full length of the left side of the cylinder block. From the pressure rail, lubricating oil passes to the main bearings of the crankshaft and through passages in the crankshaft to the big end bearings. The pistons and the cylinder bores by the oil jets which are attached the main pressure rail. Lubricating oil passes from the main bearings through passages in the cylinder block to the journals of the camshaft. The front camshaft bearings feeds oil through a drilling in the cylinder block and cylinder head to the rocker shaft. The oil passes through the center of the rocker shaft to the rocker levers. The rocker pads, valve stems, cam lobes and the tappetsare splash lubricated. The hub of the idler gear is lubricated by oil from the end pressure rail and the timing gears are splash lubricated. The lubricating oil for turbochargers is delivered by an external pipe from a tapping on the side of the cylinder block above the right hand side of filter face. The oil returns from the turbocharger down another extended drain pipe into the side of the cylinder block, or filter head, through an external pipe to the turbocharger. The oil passes through the turbocharger and returns through a pipe to the sump.

ENGINE WORKSHOP COOLING SYSTEM General description Coolant from the bottom of the radiator passes through the centrifugal coolant pump that is fitted onto the front of the timing case, to assist the flow of the coolant through the system. The coolant pump is gear driven by the fuel injection pump gear. An integral oil cooler, has an aluminium cover with a five or seven plate element. The oil cooler has no external pipes and is fitted to the left side of the cylinder block. From the pump, the coolant passes through a passage in the timing case to the coolant jacket in the top left side of the cylinder block. The coolant continues to the rear of the cylinder block where some of the coolant passes into the lubricating oil cooler. Some of the coolant passes around the element of the integral cooler and then to the rear of the cylinder block. The coolant then passes from the rear of the cylinder block and into the cylinder head. The coolant leaves the cylinder head at the front and passes into the thermostat housing. If the thermostat is closed, the coolant goes directly through a by-pass to the inlet side of the coolant pump. If the thermostat is open, the thermostat closes the by-pass and the coolant passes to the top of the radiator.

ELECTRICAL SPECIFICATIONS BATTERY

WARNING Batteries give off an explosive gas. Do not smoke when handling or working on the battery. Keep the battery away from sparks and flames. Battery electrolyte contains sulphuric acid. It may burn you if it touches your skin or eyes. Wear safety goggles. Handle the battery carefully to prevent spillage. Keep metallic items (watches, rings, zips etc.) away from the battery terminals. Such items could short the terminals and burn you. Set all switches in the cab to off before disconnecting and connecting the battery. When disconnecting the battery, take off the ground ( — ) lead first. When reconnecting, fit the positive ( +) lead first. Re-charge the battery away from the machine, in a well-ventilated area. Switch the charging circuit off before connecting or disconnecting the battery. When you install the battery on the machine, wait five minutes before connecting it up.

HMK 102 ENERGY WORKSHOP MANUAL

20 01 21

ELECTRICAL SPECIFICATIONS MAINTENANCE The following steps should be followed in order to provide optimum performance from the battery : 1 Make sure that the battery terminals are clean and tight. smear petroleum jelly on the battery terminals to prevent corrosion. 2 When applicable – never allow the electrolyte level to fall below the recommended level – 10 mm (0,4 in) above the plates. use only distilled water for topping up. 3 Keep the battery at least three quarters charged. Otherwise, the plates may become sulphated (hardened) – this condition makes recharging the battery very difficult. Extra precautions must be taken when bench charging the maintenance free batteries because they are more prone to be damaged by overcharging than the standard type of battery: Never boost-charge a maintenance free battery. Never charge a maintenance free battery at a voltage exceeding 15.8 volts. — Never continue to charge a maintenance free battery after it begins to generate gas bubbles. TESTING – SPECIFIC GRAVITY The specific gravity of the electrolyte gives an idea of the state of charge of the battery. Readings should be taken using a hydrometer, when the electrolyte temperature is 15 ºC (60 ºF). If the battery has recently been on charge, Wait approximately one hour (or slightly discharge the battery) to dissipate the surface charge before testing. Readings should be as tabulated and should not vary between cells by more than 0.04. A greater variation indicates an internal fault on that particular cell. If the electrolyte temperature is other than 15 ºC (60 ºF) a ‘correction factor’ must be applied to the reading obtained. Add 0,07 per 10 ºC (18 ºF) If the temperature is higher than 15 ºC (60 ºF) and subtract the same if the temperature is lower.

ELECTRICAL SPECIFICATIONS BATTERY TESTING This test is to determine the electrical condition of the battery and to give an indication of the remaining useful ‘life’. Before testing, ensure that the battery is at least 75 % charged (Specific gravity of 1.23 to 1.25 for ambient temperature up to 27 ºC ). Ensure that the battery is completely disconnected from the vehicle. Connect up the battery tester (part no. 993/85700) as follows: 1. 2. 3. 4. 5.

Set the check/load switch A to OFF. Set rocker switch B to the battery voltage (12 V). Connect the red flying lead to the battery positive (+) terminal and the black flying lead to the battery negative (-) terminal. Set the check/load switch a to check to read the battery no-load voltage, which should be at least 12.4 volts. Set the check/load switch a to load and hold down for 5 – 10 seconds until the meter reading stabilizes. The reading should be at least 9 volts. NOTE: Do not hold the switch in the load position for more than 10 seconds.

Remove cables from main starter terminal and solenoid terminal. using special tool 825/00410 (and adapter 825/99833 if required) unscrew three securing nuts and remove starter motor. Replace by reversing the removal sequence. DISMANTLING NOTE: Dismantle only to item 34 unless the field windings are to be renewed. Test the windings electrically before removing them from the motor yoke 15. Using a slotted steel tube, displace ring 23 to permit withdrawal of ring 22. Allow brake shoes 28 to remain in the end plate 11 unless requiring renewal. SERVICING AND RENEWAL Renew brushes 14 and 14A if their length is less than 8 mm (0.3 in.). Clean the commutator A. if individual copper bars are burned or eroded, the armature has broken windings and must be renewed. otherwise, polish with fine grade glass paper (not emery). Renew armature if commutator diameter is 38 mm (1.5in.) or less. Check the field windings for open circuits by connecting a multimeter set to measure resistance between the stud terminal B and each positive brush 14A in turn. A high or infinity reading indicates an open circuit. Similarly, connect the meter between brushes 14A and the motor yoke 15. any reading other than infinity indicates a short circuit between the coils and the yoke. renew the coils as necessary removing screws 36 with a pole shoe screwdriver C50 (obtainable from Lucas dealers). Check bronze bushes 32 and 34 for wear ASSEMBLY Align cross pin c with the notches in the brake shoes 28 before assembling brush carrier and back plate to motor yoke. Ensure that brushes 14A are correctly located in the insulated brush boxes. smear drive shaft splines and operating collar-bearing surface with grease before assembly. Assemble operating fork 19 with curved face forward the armature. set the movement of drive pinion 24 by connecting a 6v battery and switch as shown. operate switch and check dimension D. Adjust to 0.13-1.14 mm (0.005-0.045 in.) by slackening lock- nut 17 and rotating eccentric pin 18 as necessary. Re-tighten locknut.

ELECTRICAL SPECIFICATIONS ALTERNATOR

20

102 ENERGY WORKSHOP MANUAL

01 26

ELECTRICAL SPECIFICATIONS GENERAL DESCRIPTION The alternator is a three-phase generator having a rotating field winding and static power windings. When the starter switch is turned on, current from the battery flows by way of the ‘NO CHARGE’ warning light to the field winding. This creates a magnetic field, which supplements the residual magnetism in the rotor poles. As the engine is started, the fan belt drives the rotor and alternating current is generated in the power windings as they are cut by the rotating magnetic field. Output is controlled by a solid-state regulator, which varies the field current in accordance with electrical demand. Servicing is restricted to periodic inspection of slip ring brushes. Bearings are sealed for life. SERVICE PRECAUTIONS A.

Ensure that the battery negative terminal is connected to the earth cable.

B.

Never disconnect connections to the battery or alternator, or any part of the charging circuit whilst the engine is running. Disregarding this instruction will result in damage to the regulator or rectifying diodes.

C.

Main output cables are ‘live’ even when the engine is not running. take care not to earth connectors in the moulded plug if it is removed from the alternator.

D.

During arc welding on the machine, protect the alternator by removing the moulded plug (or if separate output cables fitted, remove the cables).

E.

If jump starting is necessary; connect the second battery in parallel without disconnecting the vehicle battery from the charging circuit. The booster battery may then be safely removed after a start has been obtained. Take care to connect batteries positive-to-positive, negative-to-negative.

ELECTRICAL SPECIFICATIONS Disconnect cables from rear of alternator, remove bolts A, B and C and withdraw unit from machine. Replace by reversing the removal sequence. Position the alternator until belt deflection is approximately 10 mm (3/8 in) before tightening bolts B and C. It may be necessary to slacken bolt d to allow full movement of alternator. Tighten bolt A last of all. DISMANTLING AND ASSEMBLY DISMANTLING Remove suppressor 2 (if fitted) by removing nut 1 and disconnecting lead E from terminal F. Unscrew bolts 3 and disconnect lead G from terminal H to remove the brush box and regulator assembly 4. If the brush length is less than 5 mm (0.2 in.), new length 17 mm (0.67 in), or if spring pressure is less than 1.3 N the brush box and regulator assembly must be renewed. Remove nuts and washers 5, bolts 6 and nuts 7. Remove slip ring end bracket 8. Carefully remove rectifier 10 and stator 11 as an assembly. Unsolder the interconnecting wires at X, Y and Z only if renewing either of these components. Remove nut and washer 12 using an 8 mm allen key in the shaft hexagon hole to prevent rotation. If necessary, use a press to remove rotor 19 from the drive end bracket 17. Check the rotor poles and the inner faces of the stator for signs of rubbing, which indicates worn bearings. The drive end bearing is part of bracket 17 and cannot be removed separately. if requiring renewal, needle roller bearing 20 should be pressed out in the direction of the arrow. ASSEMBLING Reverse the dismantling procedure, but note the following data: Ensure that spacers 14, 16 and 18 are correctly positioned as shown. Ensure that the slip rings J are clean and smooth, using extra fine glass paper to rectify slight imperfections. Ensure that insulation bushes 9 and washers 5 are positioned as shown. Take care not to damage the brushes when fitting the brush box and regulator assembly. TORQUE SETTINGS ITEM 3 5 6 7 12

HYDRAULIC GENERAL HYDRAULIC SYSTEM OPERATION PRINCIPLE When the control valve lever is pressed down the spool moves downward too. The neutral cave is cut, respectively the oil flow to tank is obstructed. At the same moment pressure pump line is connected to the piston side of the cylinder while the rod chamber is connected to the tank. Because of the pressure difference created between piston and rod chambers of the piston, the latter starts to move in the shown direction.

When the control lever is pressed up and the spool moves upward too. So before mentioned operation is functioning reverse side.

HYDRAULIC GENERAL CLAMPING SYSTEM Our machine has a specially designed backhoe attachment locking position for transport purposes. In this way, any load that may appear is distributed in the correct way. Otherwise, all the excessive forces that will appear during the riding will be beared by the metal frame. Also, it should be noted that the hydraulic system pressure is low while riding. This event affects negatively the clamping pressure, hence increases the possibility of impacts on the metal frame.

The correct operation of the clamping system could be checked by performing of so-called pressure loss test. It is simply required to put a “T”-connector on the clamping line and to install a 300 or 400 bar pressure gauge. With the system installed, when clamped, the pressure should be above 180 bar even when the oil called. Additionally, the mentioned above pressure should not drop more than 20 – 30 bar within 20 min interval.

DO NOT LUBRICATE the carrier rail flat surfaces (where the blockage pistons work on). As the side-shifter lock relies on the natural friction between the lock pistons and the carrier rails, any lubricant on the surfaces will affect the lock performance significantly. Thin layer of grease is allowed on the top surface of the rail only.

HYDRAULIC CONTAMINATION HYDRAULIC FLUID QUALITY Construction machinery uses different types of fluids in the hydraulic system for power transmission, equipment lubrication, and rust prevention. Seventy two percent ( 72 %) of the causes of problems in hydraulic equipment are related to the inadequate maintenance of the quality of the hydraulic fluid therefore, control of the quality of the hydraulic fluid minimizes hydraulic equipment problems and improves safety as well as reliability. EFFECTS OF CONTAMINATION Contamination greatly effects the performance and the life of the hydraulic equipment. for example , if there is a contaminant in a hydraulic pump, it develops internal wear to cause leakage and hence lower delivery output. The particles worn will cause further deterioration in the performance of the hydraulic system. Contaminants also enter principal sliding sections of the equipment causing temporary malfunction, scuffing, rubbing, sticking, chaffing and leakage and can lead to major problems seriously. THE CONTAMINANTS ARE CLASSIFIED AS FOLLOWS: 1. SOLID PARTICLES: Sand, fibres, metallic particles, welding scale, sealing materials and wear particles. 2.LIQUID: Usually water and inadequate oils and greases. 3.GASES: Air, sulphur dioxide etc. that cause corrosive compounds if dissolved in the fluid.

HYDRAULIC SERVICE

DESCRIPTION OF NEUTRAL CIRCUIT

When the hydraulic system of the machine is operated under neutral position, the hydraulic pump ( tandem, two sections, P1 & P2) receives the hydraulic fluid from the hydraulic tank and feeds this oil to the hydraulic circuit. The tandem pump is driven directly by a drive shaft. The oil fed by pump section P1, is delivered to priority valve 2. Then hydraulic oil passes to auxiliary valve 3 over priority valve. Since the auxiliary valve is in neutral position, the hydraulic oil enters loader valve block 4 through auxiliary valve. Pump section P2, feeds oil directly to loader valve. Thus, the oil fed by P1 & P2 comes together ( confluxes ) in the neutral gallery of the loader valve block and then passes to backhoe valve 5 block through high pressure carry-over line. Since the backhoe valve block is neutral position, the hydraulic fluid passes through the neutral gallery to collector over return line T4. The oil that is collected in the collector goes to oil cooler thorough pipe 4 and hose 3. then, after the cooled fluid is strained by return filter, it returns to hydraulic tank via pipe 6 and hose 8. (refer to page ’NEUTRAL CIRCUIT RETURN’)

HMK 102 ENERGY WORKSHOP MANUAL

02 HYDRAULIC SERVICE DESCRIPTION OF PUMP

The basic principle of the gear pump depends on the meshing of two spur gears, one of which is engine–driven while the other is an idler. Oil is picked up by the gear teeth on the suction side of the pump and carried out between the teeth and the pump body. As the gears come into mesh, the space carrying the oil is filled by a gear tooth on the mating gear, forcing the oil out of the space and through the pump inlet. PUMP FLOW TESTING Before removing the pump, it is necessary to determine the source of any problem by measuring the output flow at system pressure at both of the pump outlet ports. To check flow it is necessary to fit a flow meter into the output line of each pump section in turn. Make sure the flow meter is installed with its arrow pointing away from the pump and, if possible, located between pump and loader valve.

HYDRAULIC SERVICE LOADER VALVE DESCRIPTION The loader valve is mounted on the chassis frame, right hand side (when viewed from rear). Standard equipment includes loader lift spool (4J), shovel spool (4K) and un-loader valve assembly (4D). Clam shovel spool (4L) is optional. Linkage rods connect the spool ends to the control levers. OPERATION In neutral circuit hydraulic oil from pump section P2 enters the loader valve via a steering priority valve. On entering the valve block, oil flows around the waist section of the un-loader valve 3L, past a check valve and joins flow from pump P1. Oil from pump section P1 enters the loader valve as shown. Combined oil from P1 and P2 passes the main relief valve (M.R.V.- not shown) and fills the parallel gallery (1H+2H). From the parallel gallery the oil flows around the waist central portions of spools 4J, 4K and 4L (all in neutral position) and flows on to feed the excavator valve via high pressure carry over line 1B. The exhaust gallery T is connected to the tank return line.

02 HYDRAULIC SERVICE AUXILIARY RELIEF VALVE A.R.V.’s are positioned on the excavator valve block in order to relieve excessive pressure in the services. 1. VALVE AT REST Below figure shows the service in neutral with no forces acting on the equipment. The force of spring D acting through collar C keeps poppet B firmly held on its seat. Chamber J is connected to exhaust gallery via small drilled holes H, this means the pressure in the chamber will always be at the exhaust side. The A.R.V. pressure setting is adjustable by means of spring D and adjusting screw E. Turning the screw clockwise compresses the spring and therefore increases the pressure setting. Turning the screw anti-clockwise conversely, releases the spring which decreases the pressure setting. 2.

POPPET OPENS If the pressure in the service gallery A has reached the setting of the A.R.V., the pressure on the service side of the poppet is high enough to overcome the force of spring D so poppet B lifts off its seat. Oil in chamber J is displaced through small drilled holes H. Service pressure at A is now released to exhaust gallery K.

HYDRAULIC SERVICE OPERATION OF ANTI-CAVITATION When the service gallery is cavitating, the A.R.V. anti-cavitation operation allows oil from the exhaust gallery to supplement the cavitating service line. 1. OPERATION 1 When the A.R.V. is subjected to normal operating pressure in service gallery A, the force of spring F and pressure in the service gallery acting on the bottom face of anti-cavitation cone G keep the cone held firmly on its seat. 2. OPERATION 2 Whenever the service gallery is cavitating, the pressure in the exhaust gallery K is sufficient to overcome the force of spring F. The cone and the assembly move down allowing oil in the exhaust gallery and limit the effects of cavitation.

LOAD HOLD CHECK VALVES The following text describes how the load hold check valve works on the arms raise service. OPERATION 1 The weight of the loaded shovel produces a higher pressure in service line P than in parallel gallery 4O. This pressure differential causes load hold check valve 4G to close, thus preventing the load from dropping. OPERATION 2 As the neutral circuit has been blocked by the central area of the selected spool, the pressure in parallel gallery 4O increases until it is greater than that in service line P. At this point, load hold check valve 4G opens, allowing oil to flow from the parallel gallery into service line and operate the lift rams.

02 HYDRAULIC SERVICE UNLOADER VALVE ASSEMBLY Un-loader spool operation avoids overloading the engine if a service is being worked particularly hard, for example when using the excavator to tear out. It does this by dumping the oil from pump section P2 to tank, allowing engine power to be applied fully to the main pump section P1. The un-loader is operated automatically when the system pressure reaches 210 bar. The un-loader is operated manually. This is referred to as HYDRAULIC SPEED CONTROL (HSC). The main applications for manual operation are: 1. 2. 3.

More traction force is made available to the loader end when entering a stock pile. More power from the engine is made available while traveling on the highway, providing improved fuel economy. Reduced backhoe speed when placing objects. (sensitivity)

HYDRAULIC SERVICE SYSTEM OPERATION Pressure in the inlet gallery C rises to the setting of pilot valve 4f via the bore of the spool 4D. At pressure below the setting of the un-loader valve, both pilot valve 4F and the spool 4D remain closed. If the pressure in the inlet gallery C rises to the setting of pilot valve 4F, this valve will open, allowing oil in spring cavity 3P to escape more quickly than it can be replaced by oil entering through the small drilling D. This creates a pressure differential between the spring cavity 3P and gallery C. Higher pressure in gallery C acts on the face of spool 4D causing the spool to be moved off its seat. Oil entering the valve block from pump P2 now flows directly to tank (T). High pressure in gallery C also holds check valve 4C firmly closed, preventing oil of pump P1 from being dumped too. When pressure in the inlet gallery C falls, for example if the excavator has stopped tearing out, pilot valve 4F will be at the same pressure as oil in gallery C, spring pressure will move spool 4D back onto its seat, closing pump P2 connection to tank.

HYDRAULIC SPEED CONTROL (HSC) Solenoid valve 4e is connected between the un-loader valve chamber 3P and the return to tank circuit. When the solenoid is de-energized spring force acting on the end of the spool keeps the connection from chamber 3P to tank closed. When the solenoid is energized by the switch in the cabin manually, the spool moves causing a connection from the un-loader spool chamber 3P to the hydraulic tank via valve block internal galleries and service hoses. Because the un-loader chamber is now connected to the tank and so at exhaust pressure, pressure in gallery C acts on the face of un-loader spool 4D causing the spool to be moved off its seat. Oil entering the valve block from pump section P2 now flows directly to tank. Therefore, hydraulic oil flow in the system can be decreased manually whenever required.

02 HYDRAULIC SERVICE MAIN RELIEF VALVE 1. VALVE AT REST Main relief valve (M.R.V.) 4B is positioned in the loader valve block in order to relieve excessive pressure in the hydraulic system. When the hydraulic system is in neutral or under light load and there are no excessive forces acting on the equipment, hydraulic system pressure that enters chamber D through the small drilling e will not be sufficient to move the main plunger a off its seat B. The force of spring g is adjustable to suit the relevant service by means of adjuster at the top of the valve. As long as the pressure does not continue to rise, plunger a will remain on its seat. 2. PILOT VALVE OPENS as the system pressure increases sufficient to force the pilot valve f that moves against spring G, the pressurized oil in chamber D is allowed to escape into cavity K and to pass down the sides of sleeve J into the exhaust gallery H. 3. MAIN VALVE OPENS as system pressure reaches the setting of the valve, pressure in chamber D can not rise because the seat orifice of pilot valve f is larger than small drilling e and oil is can not fil the chamber as fast as it is being exhausted. Pressure acting on the lower faces of main plunger A is obviously greater than the combined force of both spring C and the pressure in chamber D. then, the plunger moves off its seat, allowing pressure to be vented into the exhaust gallery H. As the system pressure decreases, the pilot valve can close and pressure in chamber D helps spring C to push the main plunger a back to its seat.

VALVE AT REST Figure shows the service in neutral with no forces acting on the equipment. The force of spring D acting through collar C keeps poppet B firmly held on its seat. Chamber J is connected to exhaust gallery via small drilled holes H, this means the pressure in the chamber will always be at exhaust. The A.R.V. pressure setting is adjustable by means of spring D and adjusting screw E. Turning the screw clockwise compresses the spring and therefore increases the pressure setting. Conversely, turning the screw anti-clockwise, releases the spring which decreases the pressure setting. 2. POPPET OPENS If the pressure in the service gallery A has reached the setting of the A.R.V., the pressure on the service side of the poppet is high enough to overcome the force of spring D so poppet B lifts off its seat.

ANTI-CAVITATION OPERATION When the service gallery is cavitating, the A.R.V. anti-cavitation operation allows oil from the exhaust gallery to supplement the cavitating service line. OPERATION 1: When the A.R.V. is subjected to normal operating pressure in service gallery A, the force of spring f and pressure in the service gallery acting on the bottom face of anticavitation cone G keep the cone held firmly on its seat. OPERATION 2: When the service gallery is cavitating, the pressure in exhaust gallery k is sufficient to overcome the force of spring F. The cone and its assembly move down allowing oil in the exhaust gallery to enter the service gallery and limit the effects of cavitation. When the service gallery is no longer cavitating, compressed spring f will return to its relaxed position and thus bring the anti-cavitation cone back onto its seat.

02 HYDRAULIC SERVICE HYDRO-CLAMP OPERATION (SIDESHIFT MACHINES) When the backhoe is being used for excavation, the kingpost assembly must be ‘clamped’ to the side-shift rear frame. The hydro-clamp control valve assembly (items G,D and C) is positioned in the inlet end of the excavator valve block and is connected directly to the parallel gallery B. The valve operates in conjunction with solenoid valve E housed in the side of the excavator valve block. 1. CLAMPS PRESSURIZED When the hydro-clamp control lever is pushed downwards the hydro-clamp valve is closed. The control lever of jaw bucket is hold steadily until M.R.V. relieves pressure fully. this situation builds maximum pressure in parallel gallery. In this case, hydroclamp check valve opens and let the maximum pressure enter to hydro-clamp piston when the lever of jaw bucket is released, the hydro-clamp check valve takes its position and let the oil blocked in pistons. In other words pistons are blocked in pressurized condition and clamps are pressurized. 2. CLAMPS RELEASED When hydro-clamp lever is pulled upwards the hydro-clamp valve housing is being turned clockwise and begin to spin until check valves stand to H. Then, the check valve takes off its position. In this case, the pressurized oil in hydro-clamp circuit is released to tank from the clearance that is formed by check valve. This means, the clamps are released. 3. CLAMPS LOCKED UP If no service is being operated, pressure in the parallel gallery falls to that of the neutral circuit and the force of spring G is sufficient to keep the poppet seated. Therefore, pressure is trapped in the line to the clamps, keeping the excavator end in a securely clamped condition.

When fitted, the proximity switch setting procedure is the same for both off-set (front) and central (rear) drive head axles. The illustration shows a central drive head axle. —

—

—

—

—

Park the machine on a level ground. Lift the machine sufficient enough the raise the wheels off the ground. Perform the Steering System Bleeding Procedure if any steering cylinder is dismantled for servicing before. Align the wheels in the straight ahead position. Check if straight ahead by measuring X and Y at the given illustration. The measurement X should be equal to the measurement Y. See Link Arms Removal and Replacement, Section:Replacement for correct wheel alignment on page E5-16. Remove the proximity switch cover C. Loosen the bracket fixing bolts E and slide the assembly just in line with the target disc A for lateral adjustment. With the starter switch on, loosen the proximity switch lock nut D. Make sure the light emitting diode (L.E.D.) is not illuminated (if it is so then screw the proximity switch out). Now, screw the proximity switch towards the target disc A until the light emitting diode (L.E.D.) on the proximity switch illuminates. Add a further 1 to 1,5 turns. Tighten the locknut.

NOTE: Take care not to overtighten the locknuts. Otherwise, the threads on the proximity switch may be damaged. 8

Refit the proximity switch cover C.

CHASSIS TRANSMISSION

TROUBLE SHOOTING This list of possible failures and remedies provides no more than an indication of what the problem might be and how to fix it. It should be remembered that problems are not caused by just one part, but by the part’s interaction with other elements; accordingly, additional action over and above the steps described is frequently required. This list may not cover all possible problems and remedies. Specialist personnel must identify the problem and its cause and the n proceed with the necessary repairs. Warning ! All checks and tests must be performed with the oil at working temperature : 80 ± 2 0C CHECKS & TESTS Transmission oil check Always check the correct oil level and correct oil specifications. Pressure check Several transmission breakdowns can be identified by running pressure checks. Irregular measurements might indicate that there is a problem, which specialist personnel must identify. 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 80 ± 2 0C, allowing any problems in the engine, converter or transmission to be identified. Proceed as follows:  Check the oil level.  Activate the parking brake to block the wheels.  Start the engine and keep it ticking over at idle speed (800 – 1000 rpm).  Put the gear lever into 4th.  Put the reverser in the FORWARD position.  Rev the engine for short periods to a maximum of 1500 – 1700 rpm, to bring the oil up to working temperature. Important : The converter stall test must not exceed a maximum duration of 30 seconds each time. After this 30 seconds period, put the reverser in NEUTRAL for 15 seconds, then repeat the procedure. Warning ! Failure to keep to these test periods may result in the oil overheating and attendant damage to the clutches, filter, converter and seals.  Gradually reduce the engine revs to minimum.  Put the reverser in NEUTRAL.

CHASSIS TRANSMISSION TROUBLESHOOTING This list of possible failures and remedies provides no more than an indication of what the problem might be and how to fix it. It should be remembered that the problems are not caused by just one part, but by part’s interaction with other elements. Accordingly, additional action over and above the steps described is frequently required. This list may not cover all possible problems and remedies. Specialist personnel must identify the problem and its cause and then proceed with the necessary repairs. Warning: All checks and tests must be performed with the oil at working temperature 80 ± 2 0C. CHECKS AND TESTS Transmission oil check Always check the correct oil level and correct oil specification. Pressure test Several transmission breakdowns can be identified by running pressure checks. Irregular measurements might indicate that there is a problem, which specialist personnel must identify. 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 ± 2 0C, allowing any problems in the engine, converter or transmission to be identified. Proceed as follows:  Check the oil level.  Apply the parking brake to block the wheels.  Start the engine and keep it ticking over at idle speed (88-00-1000 rpm).  Put the gear lever into 4th.  Put the reverser in the FORWARD position.  Rev the engine for short periods to a maximum of 1500-1700 rpm, to bring the oil up to working temperature. Important: The converter stall test must not exceed a maximum duration of 30 seconds each time. After this 30 sec period, put the reverser in NEUTRAL for 15 seconds than repeat the procedure. Warning: Failure to keep to these test periods may result in the oil overheating and attendant damage to the clutches, filter, converter and seals.  Gradually reduce the engine revs to minimum.  Put the reverser in NEUTRAL.

01 TIRE GENERAL

Proper tire care and safety is simple and easy. The Rubber Manufacturers Association (RMA) recommends getting in the habit of taking five minutes every month to check your tires, including the spare.

It’s important to have the proper air pressure in your tires, as under inflation may lead to tire failure. The right amount of air for your tires is specified by the vehicle manufacturer and is shown on the vehicle door edge, door post, glove box door or fuel door. It is also listed in the owner’s manual. 1. When you check the air pressure, make sure the tires are cool — meaning they are not hot from driving even a mile. (NOTE: If you have to drive a distance to get air, check and record the tire pressure first and add the appropriate air pressure when you get to the pump. It is normal for tires to heat up and the air pressure inside to go up as you drive. Never «bleed» or reduce air pressure when tires are hot.) 2. Remove the cap from the valve on one tire. 3. Firmly press a tire gauge onto the valve. 4. Add air to achieve recommended air pressure. 5. If you overfill the tire, release air by pushing on the metal stem in the center of the valve with a fingernail or the tip of a pen. Then recheck the pressure with your tire gauge. 6. Replace the valve cap. 7. Repeat with each tire, including the spare. (NOTE: Some spare tires require higher inflation pressure.) 8. Visually inspect the tires to make sure there are no nails or other objects embedded that could poke a hole in the tire and cause an air leak. 9. Check the sidewalls to make sure there are no gouges, cuts, bulges or other irregularities. NOTE: Air pressure in a tire goes up (in warm weather) or down (in cold weather) 1-2 pounds for every 10 degrees of temperature change.

TIRE GENERAL

Misalignment of wheels in the front or rear can cause uneven and rapid tread wear and should be corrected by a tire dealer. Front-wheel-drive vehicles, and those with independent rear suspension, require alignment of all four wheels. Have your alignment checked periodically as specified by the vehicles’ owners manual or whenever you have an indication of trouble such as «pulling» or vibration. Also have your tire balance checked periodically. An unbalanced tire and wheel assembly may result in irregular wear.

Sometimes irregular tire wear can be corrected by rotating your tires. Consult your vehicle’s owners manual, the tire manufacturer or your tire dealer for the appropriate rotation pattern for your vehicle. NOTE: If your tires show uneven wear, ask your tire dealer to check for and correct any misalignment, imbalance or other mechanical problem involved before rotation. Before rotating your tires, always refer to your car’s owner’s manual for rotation recommendations. If no rotation period is specified, tires should be rotated approximately every 6,000 miles

Tires must be replaced when the tread is worn down to 1/16 of an inch in order to prevent skidding and hydroplaning. An easy test: place a penny into a tread groove. If part of Lincoln’s head is covered by the tread, you’re driving with the proper amount of tread. If you can see all of his head, you should buy a new tire. Built-in tread wear indicators, or «wear bars,» which look like narrow strips of smooth rubber across the tread will appear on the tire when the tread is worn down to onesixteenth of an inch. When you see these «wear bars,» the tire is worn out and should be replaced. Visually check your tires for signs of uneven wear. You may have irregular tread wear if there are high and low areas or unusually smooth areas. Consult your tire dealer as soon as possible.

History of Hidromek Tractors

Some HIDROMEK Tractor Service Manuals PDF are above the page.

The first factory Hidromek opened in Ankara in 1986.

And already in 1989, the production of its own excavator-loader NMK-80 started. It was the first Turkish-made excavator.

The company grew at a very fast pace, and in 1996 the company built its own factory, which established the production of massive steel welded parts.

The company’s headquarters also moved here.

Naturally, everything built on the outskirts of Ankara.

The growth of the enterprise led to the fact that there was not enough space to collect the equipment, and the company build another plant.

What was successfully done in 2001.

The assembly of excavator loaders moved to the new plant, which was built in the free economic zone of Izmir.

In Ankara in 2006, Hidromek built another plant. Now for the assembly of wheeled and tracked excavators Hidromek.

We draw your attention to how quickly the company was developing! But it engaged in mechanical engineering, and not in gas or oil trade.

The company produces the most complex construction machines of its own design.

If you compare Hidromek with many American and European companies, then it is on the market relatively recently.
