Engine Lubrication: Description and Operation

ENGINE LUBRICATION SYSTEM







The lubrication system is a full flow filtration pressure feed type. Oil stored in the oil pan is taken in and discharged by an internal gear type oil pump directly coupled to the crankshaft. Its pressure is regulated by two relief valves located in the Chain Case Cover. The oil is pumped through an oil filter and feeds a main oil galley.This oil gallery feeds oil under pressure to the main and rod bearings, camshaft bearings. Passages in the cylinder block feed oil to the hydraulic lifters through hollow pushrods which feeds the rocker arm socket.
