Power units are designed for operation at ambient temperatures from minus 60ºС to plus 50ºС, relative humidity up to 98% at a temperature of 25ºС, air dust content up to 0.4 g / m 3, as well as for movement car in mountainous conditions at an altitude of up to 4500 m above sea level and overcoming passes up to 4650 m above sea level with a corresponding decrease in power and economic indicators.

Let's consider the malfunctions that may occur during engine operation:

  • - The crankshaft is not turned by the starter;

The full-flow oil filter (Fig. 1) is secured with three bolts to the right side of the lower part of the crankcase through a gasket and consists of a housing 11, caps 17 and two filter elements

  • - it is not necessary to remove the engine to remove the cylinder head
  • - to prevent damage to the paintwork of the wings of the body, it is necessary to use a special coating
  • - to prevent damage to the cylinder head, before removing it, you must wait until the engine cools down

To assemble the engine, as well as to disassemble it, the engine cylinder block assembled with the clutch housing is fixed on a stand (see Fig. 1)

Before assembly, all engine parts are selected according to size, thoroughly washed, blown with compressed air and wiped with clean napkins

The geometry of the repaired body is determined:

  • - the size of the gaps on the doors, hood and trunk lid;
  • - installation angles of the steered wheels;
  • - relative position of suspensions, bridges.

Synchronization of the crankshaft and fuel injection pump drive gearbox shaft pulse wheels D-245E3

The need to install (reinstall) the crankshaft and fuel injection pump drive gearbox shaft pulse wheels for their synchronization may be caused by dismantling the fuel injection pump drive gearbox during routine repairs of the diesel engine

Installing cylinder heads, valve rocker arms and adjusting valve clearances

The cylinder head mounting studs are screwed into the right and left rows of the cylinder block, having previously lubricated the threaded holes for the studs in the block with diesel oil

By default, we already have the cylinder head removed

The clearance in the valve mechanism must ensure a tight fit of the valve to the seat when the rod elongates due to heating and in the event of the head settling in the seat due to wear of the chamfers
