Lubrication System

This engine uses a full pressure lubrication system which delivers oil under pressure to crankshaft, camshaft,

connecting rod bearing surfaces, and hydraulic valve lifters.

A high-eﬃ ciency gerotor oil pump maintains high oil ﬂ ow and oil pressure, even at low speeds and high operating

temperatures. A pressure relief valve limits maximum pressure of system. Closure plate must be removed to service

oil pickup, pressure relief valve, and oil pump.
