Engine Lubrication: Description and Operation

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 pump directly coupled to the crankshaft. Its pressure is regulated by the relief valve located in the chain case cover. The oil is pump through an oil filter and feeds three main oil gallery. This oil gallery feeds oil under pressure to the main and rod bearings and camshaft bearings. Passages in the cylinder block feed oil to the hydraulic lifters through hollow push rods which feeds the rocker arm sockets.
