Lubrication system device
1 - oil pump; 2 - oil crankcase; 3 - oil supply channel from the pump to the filter; 4 - a horizontal channel in the cylinder block for supplying oil from the filter to the oil line; 5 - a channel in the cylinder block for supplying oil to the drive gear of the oil pump and the ignition distributor; 6 - channel in the neck of the crankshaft; 7 – an 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 - bushing of the gear wheel of the oil pump drive and the ignition distributor; 10 - roller drive oil pump and ignition distributor; 11 - channel for draining oil into the crankcase; 12 - camshaft pulley; 13 – an epiploon of a camshaft; 14 - channel in the camshaft cam; 15 - main channel in the camshaft; 16 - channel in the camshaft bearing journal; 17 - camshaft bearing housing; 18 - annular undercut on the middle support neck; 19 - oil filler cap; 20 - an inclined channel in the cylinder head for supplying oil to the gas distribution mechanism; 21 - vertical channel in the cylinder block; 22 - oil line; 23 – the gauge of a control lamp of pressure of oil; 24 - oil supply channel to the main bearing; 25 - oil supply channel from the main bearing to the connecting rod; 26 - crankshaft; 27 - oil level indicator; 28 - oil filter
Combined lubrication system. Under pressure, the main and connecting rod bearings, bearings and camshaft cams, roller bearings 10 and the oil pump drive gear 1 and the ignition distributor are lubricated.
The oil flowing from the gaps and splashed 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.
Oil pump 1 - gear type, with a pressure reducing valve, is installed inside the crankcase and is attached to the cylinder block with two bolts.
Oil filter 28 - full-flow, non-separable, with bypass and anti-drain valves.
