  Dear Customer, The powerful and cost-effective powertrains and engines which you are beginning to use are reliable and easy to operate. However, it should be remembered that their lifetime largely depends on their regular and careful maintenance. Therefore, before starting operation, please CAREFULLY read this manual and strictly follow the rules…

• Page 4: Warning

  WARNING 1. Failure-free functioning of the engine and its long operating life depend directly on their correct handling. Therefore carefully read this manual before starting the operation. 2. During the engine break-in period its mating parts become aligned, therefore further working efficiency largely depends on how strictly the rules specified in the NEW ENGINE BREAK-IN section have been followed.

  BASIC PARTS CYLINDER BLOCK AND CYLINDER LINERS The six-cylinder block is made of grey cast iron. It serves as a mounting base for all engine parts and units. Each cylinder liner seat bore has a circular groove for the liner collar in the upper part and a cylinder-shaped hole in the lower part made coaxially.

• Page 54: Cylinder Head

  The year of manufacture and the engine serial number are marked on a special flat area of the cylinder block located on its front, on the left, near the generator (See Fig. 4, item 6). In the top left part of the block there is a tunnel with seven seat bores for the camshaft.

  LUBRICATION SYSTEM The engine lubrication system is a mixed-type wet-sump system. The oil pump sucks oil from the oil sump through the suction pipe intake and a safety valve and supplies it to the system through the in-line liquid-oil heat-exchanger (L/O HE) and the oil filter (OF). The L/O HE is installed in the service module housing which also incorporates the lubrication system differential valve, the water pump and the thermostat box.

• Page 77: Oil Filter

  ATTENTION! THE HIGH-PRESSURE FUEL PUMP IS LUBRI- CATED BY THE OIL CIRCULATING INSIDE ITS HOUSING. OIL PUMP The oil pump is mounted on the rear side of the cylinder block and can only be accessed when the flywheel housing is removed. The oil pump safety valve is installed on the cylinder block lower flange in the oil pump feed pipe and can be accessed when the oil sump is removed.

• Page 78
  When installing the filter, screw on the replaceable filter by hand as far as it will go. LUBRICATION SYSTEM DIFFERENTIAL VALVE The lubrication system oil pump capacity is calculated with allowance for worn-out friction pairs of the engine which has been in operation until its scheduled overhaul, including low-speed operation mode.

• Page 79: Cooling System

  COOLING SYSTEM The engine cooling system is a liquid circulation system consisting of a water pump, a liquid-to-oil heat exchanger (L/O HE), a fan, thermostats and an exhaust gas recirculation (EGR) heat exchanger. The cooling system also includes a vehicle-mounted water radiator and an air-to-air charge air cooler.

• Page 80
  The EGR heat exchanger is located above the cylinder head water distribution pipe. Part of the liquid from the pipe goes to the heat exchanger through the bushing with a rubber ring, cools down exhaust gases and is drained through the external pipe to the service module water collecting channel.

  TURBOCHARGER SYSTEM GENERAL DESCRIPTION To ensure the required power output, the engine is equipped with a turbocharger that uses the energy of exhaust gases to force more air into the engine. By increasing the mass of the air entering the cylinders, the turbocharger contributes to more effective burning of higher amount of fuel thus increasing the engine power.
• Page 103
  The heat released to the environment by the air-to-air type cooler of the YMZ-536 engine can reach the value up to 57 kW. The charge air cooler is not part of the engine supply kit and is mounted in the vehicle upstream the cooling system radiator.

  CRANKCASE VENTILATION SYSTEM The crankcase ventilation system is a closed-type system (see Fig. 37). During the engine operation some amount of exhaust gases from the cylinders enter the crankcase where they are mixed with oil mist and sent to the turbocharger suction. To prevent oil coking in the turbocharger, crankcase gases are separated from oil in the breather 2.

  EXHAUST BRAKE When it is necessary to use sustained braking (e.g. for a long- time downhill movement), the driver, without disengaging the clutch, cuts off the fuel supply and shifts to the lowest gear. In this case the engine starts operating as an air compressor, with the rpm depending on the vehicle movement speed.
