Engine Lubrication: Description and Operation

A gear type oil pump is attached to the bottom side of the rear main bearing cap and is driven by the camshaft through an intermediate shaft. Oil flows through the pump outlet tube to the cooler located in the radiator. A bypass valve is incorporated into the system, which allows oil to bypass the cooler and continue to feed the engine should the cooler become clogged. From the cooler, the oil then flows through a cartridge type oil filter. A bypass valve is incorporated into the system to prevent oil starvation should the filter become clogged.
