Lubrication system device
1 – oil pump; 2 – oil pan; 3 – oil supply channel from the pump to the filter; 4 – horizontal channel in the cylinder block for supplying oil from the filter to the oil line; 5 – channel in the cylinder block for supplying oil to the gear drive of the oil pump and ignition distributor; 6 – channel in the crankshaft journal; 7 – crankshaft oil seal; 8 – oil supply channel from the oil line to the main bearing and to the drive shaft of the oil pump and ignition distributor; 9 – bushing of the gear of the oil pump and ignition distributor drive; 10 – oil pump and ignition distributor drive shaft; 11 – channel for draining oil into the engine crankcase; 12 – camshaft pulley; 13 – camshaft oil seal; 14 – channel in the camshaft cam; 15 – main channel in the camshaft; 16 – channel in the bearing journal of the camshaft; 17 – camshaft bearing housing; 18 – annular groove on the middle support neck; 19 – oil filler cap; 20 – inclined channel in the cylinder head for supplying oil to the valve timing mechanism; 21 – vertical channel in the cylinder block; 22 – oil line; 23 – Oil pressure warning light sensor; 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
The lubrication system is combined. The main and connecting rod bearings, supports and cams of the camshaft, bearings of the shaft 10 and the gear of the drive of the oil pump 1 and the ignition distributor are lubricated under pressure.
The oil flowing out of the gaps and splashed by the moving parts lubricates the cylinder walls, pistons with piston rings, piston pins in the piston bosses, the camshaft drive chain, the valve drive lever bearings, and also the valve stems in their guide bushings.
When the oil pressure drops below the permissible level, the low oil pressure indicator lamp lights up.
Oil pump 1 is a gear type with a pressure reducing valve, installed inside the crankcase and attached to the cylinder block with two bolts.
Oil filter 28 – full-flow, non-separable, with bypass and anti-drain valves.
