CAMSHAFT INSTALLATION
Install Tool C-3509 in place of distributor drive
gear and stub shaft (Fig. 39). Hold tool in
position with distributor lock plate screw. This
tool will restrict the camshaft from being
pushed in too far and prevent knocking out
the Welch plug, and should remain installed
until camshaft and crankshaft sprockets and
timing chain have been installed. Lubricate
camshaft lobes and camshaft bearing journals
and install camshaft being careful not to dam-
age cam bearings with the cam lobes. Install
thrust plate spacer (chamfered side toward
camshaft fillet). Install thrust plate and oil
trough; tighten screws 15 foot-pounds torque.
Check difference in thickness between spacer
and thrust plate. The spacer should be thicker
than thrust plate to extent that camshaft must
have an end play of .002 to .006 inch.
NOTE:
Whenever an engine has been rebuilt
and a new camshaft and or new tappets have
been installed, one quart of MOPAR Oil Ad-
ditive should be added to the engine oil to aid
break in. The oil mixture should be left in the
engine for a minimum of 500 miles. However,
it is not necessary to drain the mixture before
normal oil change is required, nor is it neces-
sary to use the oil additive at subsequent oil
changes.
