Engine Oiling System
Full pressure lubrication system with gear type oil pump. Oil pump is mounted at front of engine and driven by the camshaft. Oil is pumped through oil cooler into oil passages. Crankshaft main and connecting rod journals oil through cross drilled holes in crankshaft. Oil is pumped to camshaft through oil passages that also lubricate valve tappets. Oil flows through tappets and into push rods to lubricate rocker arms and shafts. Valves and valve stems are lubricated by splash oil. Excess oil flows back into crankcase through push rod tubes. Cylinder walls, pistons and piston pins are oiled by splash oil.
