Engine Oiling System
Oil is circulated through engine by pressure provided by a gear type oil pump. Pump is mounted on bottom of crankcase and driven by the auxiliary shaft. Oil is drawn from oil pan by oil pump and circulated through a full flow oil filter. Oil is then pumped into main oil gallery of crankcase where it is distributed to crankshaft and camshaft. Oil flows through crankshaft to lubricate main and connecting rod bearings. Cylinders, pistons and piston pins are lubricated by oil squirted from hole in connecting rod. Oil flows through camshaft to journals. Oil is squirted from number two and four journal to lubricate valve tappets and valves. Auxiliary shaft is lubricated by oil from main oil gallery. Excess oil flows back into oil pan.
