2.1.6. Lubrication system of engines

The lubrication system under pressure created by the gear pump with internal gearing and an excentric rotor provides lubricant of a bent shaft, the top heads of rods and bearings of the camshaft. From 1985 model years oil from lubricant system is brought under pressure to the hydraulic pushers providing automatic compensation of gaps in the gas distribution mechanism.

Oil pump

The leading gear wheel of the oil pump is established on two lyska on the forward end of a bent shaft (between an asterisk of a bent shaft and a pulley of a belt of the drive of auxiliary units). The pump housing is executed directly in a cover of the drive of the camshaft and closed from the engine by a cover.
