Malfunctions of pneumatic drive power supplies

When servicing the pneumatic drive of the car brakes, you must first of all make sure that the system is tight

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.

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 cylinder heads are separate for each cylinder, made of aluminum alloy. They have water cavities communicating with the same cavities of the cylinder block, inlet and outlet channels, plug-in seats and valve guides.
