LUBRICATION S Y S T E M
The lubrication system is a full flow filtration pres­
sure 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

bearings. Passages in the cylinder block feed oil to
the hydraulic lifters through hollow push rods which
feeds the rocker arm sockets.
