Lubrication Description
SIE-ID = 650073
The gear-type oil pump is driven through an extension
driveshaft. The extension driveshaft is driven by the
distributor which is gear driven by the camshaft. The oil
is drawn from the oil pan through a pickup screen
and tube. Pressurized oil is delivered through internal
passages in order to lubricate the camshaft and
the crankshaft bearings and to provide lash control in
the hydraulic valve lifters. Oil is metered from the
valve lifters through the valve pushrods in order
to lubricate the valve rocker arms and valve rocker
arm ball pivots. Oil returning to the oil pan from
the cylinder heads and the camshaft front bearing,
lubricates the camshaft timing chain and the crankshaft
and the camshaft sprockets.
