REMOVAL AND INSTALLATION OF
DISTRIBUTOR DRIVE SHAFT BUSHING
a. Removal (Camshaft Removed)
Insert Tool C-3052 into old bushing and thread
down until a tight fit is obtained, (Fig. 40).
Hold puller screw and tighten puller nut until
bushing is removed.
b.
Installation
Slide new bushing over burnishing end of Tool
C-3053 and insert tool and bushing into bore.
Drive bushing and tool into position, using a
soft hammer. As the burnisher is pulled through
bushing by tightening puller nut, the bushing
is wedged tight in block and burnished to cor-
rect size. DO NOT REAM THIS BUSHING.
24.
CAMSHAFT INSTALLATION
Install Tool C-3509 in place of distributor drive
gear, and stub shaft (Fig. 41). 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 bearing journals and in-
stall camshaft being careful not to damage 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 in-
stalled, one quart of MOPAR Oil Additive
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 necessary to
use the oil additive at subsequent oil changes.
25.
DISTRIBUTOR (BASIC) TIMING
Before installing the distributor drive shaft
and gear, it will be necessary to time engine as
follows: Rotate crankshaft until Number 1
cylinder is at top dead center (check with Tool
C-3075). When in this position, the pointer on
chain case cover should be over ("DC") on
vibration damper. Position oil pump shaft so
that it lines up with slot in drive gear. Coat
shaft of drive gear with engine oil. Install so
that, after gear spirals into place, it will index
with oil pump shaft, and slot in top of drive
