The lubrication system operates under pressure. Oil from the engine crankcase is fed under vacuum through the mesh filter of the oil receiver to the gear-type oil pump with internal engagement and an eccentric drive gear, the drive of which is carried out directly from the crankshaft. The oil filter is connected in series with the main oil line of the engine. It has a bypass valve that allows uncleaned oil to pass into the oil line when the filter element is clogged. In this case, oil is fed under pressure to the main bearings of the crankshaft and to the connecting rod bearings through the channels of the cylinder head to the supports of the camshaft.
Oil pump
The oil pump is installed in the front cover of the cylinder block. The oil pump cover contains a pressure reducing valve.
The oil pressure indicator lamp in the instrument cluster goes out when the oil pressure in the system is 0.15-0.45 kg/cm.
Oil pressure at crankshaft speed of 2000 rpm and oil temperature of 80°C, not less than, kg/cm: 2+0.2.
The gap between the ends of the gears and the plane of the pump body, mm: 0.03-0.06.
Gap between gear teeth, mm: 0-0.13.
Motor oil
Lubrication system capacity, l: 3.5 (including 0.5 l in the oil filter).
Used oil: SAE 5W20, 10W40, 15W50, 20W40; by API SE.
Oil change frequency: every 15,000 km with replacement of the oil filter.
