2-4. ENGINE LUBRICATION. (Figure 2-2)
a. Engine lubrication is controlled by a crankshaft driven oil pump (11, Figure 2-2). The oil pump is
housed in the engine crankcase and supplies all oil to lubricate and cool high friction internal components. The
crankcase acts as the oil sump, since a separate oil pan does not exist. The oil pump draws oil from the oil
sump through an oil filter (7). After the oil passes through the filter, it is carried through oil passages to
lubricate the crankshaft and camshaft bearings.
b. Oil level in the crankcase is measured using a gauge attached to the oil fill cap. Markings on the
gauge indicate the amount of oil in the engine. An engine drain plug allows the engine oil to be drained to a
pan during servicing.
