Lubrication system
1 - oil pump; 2 - oil crankcase; 3 - oil supply channel from the pump to the filter; 4 - a horizontal channel for supplying oil from the filter to the oil line; 5 - channel for supplying oil to the drive gear of the oil pump and the ignition distributor; 6 - channel in the neck of the crankshaft; 7 – a forward epiploon of a cranked shaft; 8 - oil supply channel from the oil line to the main bearing and to the oil pump drive shaft and ignition distributor; 9 – a gear wheel of a drive of the oil pump and the distributor of ignition; 10 - roller drive oil pump and ignition distributor; 11 – channel for oil drain; 12 - channel in the camshaft cam; 13 - main channel in the camshaft; 14 - channel in the camshaft bearing journal; 15 - an annular groove on the middle bearing neck of the camshaft; 16 - oil filler cap; 17 - inclined channel in the cylinder head; 18 - vertical channel in the cylinder block; 19 - oil line; 20 – the gauge of a control lamp of pressure of oil; 21 - oil supply channel to the main bearing; 22 - oil supply channel from the main bearing to the connecting rod; 23 - oil level indicator; 24 - oil filter
Combined lubrication system. Under pressure, the main and connecting rod bearings, supports and camshaft cams, roller bearings 10 and gear 9 of the oil pump drive 1 and ignition distributor are lubricated. The oil flowing from the gaps and sprayed by moving parts lubricates the cylinder walls, pistons with piston rings, piston pins in the piston bosses, the camshaft drive chain, valve lever bearings, and valve stems in their guide bushings.
When the oil pressure drops below the allowable value, the low oil pressure warning lamp lights up.
The gear type oil pump is mounted inside the crankcase and is attached to the cylinder block with two bolts.
Oil filter - full-flow, non-separable, with bypass and anti-drain valves.
