CAMSHAFT
Removal
The camshaft thrust is forward with the 273 and
318 Cubic Inch Engines, and a thrust plate is used to
control the .002 to .006 inch end play. The 361, 383
and 426 Cubic Inch Engines camshaft thrust is rear-
ward only. Thrust is taken by the rear face of the
cast iron camshaft sprocket hub, bearing directly on
the front face of the cylinder block, eliminating the
need for a thrust plate.
(1) With the tappets and timing sprockets removed,
remove the distributor and lift out the oil pump and
the distributor drive shaft.
(2) On 361, 383 and 426 Cubic Inch Engines, re-
move the fuel pump to allow the push rod to drop
away from the cam eccentric.
(3) Install a long bolt into the front of the camshaft
to facilitate the removal of the camshaft; remove the
camshaft being careful
not
to damage the cam bear-
ings with the cam lobes.
lnstallation
(1) Lubricate the camshaft lobes and camshaft bear-
ing journals and insert the camshaft to within M
inch of its final position in the cylinder block.
(2) Install Tool C-3509 as described in paragraph
"Timing Chain and Sprocket."
(3) Push the camshaft into the final position.
(4) Keep the tool in place until the sprockets and
the chain have been installed. Complete installation
as
described
in
Paragraph "Timing Chain and Sprock-
ets."
NOTE: Whenever an engine has been rebuilt and
a new camshaft and/or new tappets have been in-
stalled, one quart of factory recommended oil ad-
ditive should
be
added to the engine oil to aid in
break-in. The oil mixture should be left in the en-
gine for a minimum of
500
miles. Drain the oil mix-
ture at the next normal oil change.
NOTE: Whenever the camshaft
i s replaced,
all
of
the tappet faces must be inspected for crown with
a straightedge. If any negative (crown dish)
is ob-
served, the tappet must be replaced.
CAMSHAFT
BEARINGS
(Engine Removed from Vehicle)
Removal
(1) With the engine completely disassembled, drive
out the rear cam bearing welch plug.
(2) Install the proper size adapters and horse shoe
washers (part of Tool C-3132A) at the back of each
bearing shell to be removed and drive out the bearing
shells.
Installation
(1) Install the new camshaft bearings with
Tool
C-3132A by sliding the new camshaft bearing shell
over the proper adapter.
(2) Position the bearing in the tool. Install the horse
shoe lock and by reversing the removal procedure,
carefully drive bearing shell into place, as shown in
Figure 95.
(3) Install the remaining shells in like manner.
NOTE: Install the NO.

camshaft bearing
1/32"
in-
ward from the front face of the cylinder block.
The oil holes in the camshaft bearings and cylinder
block must be in exact alignment to insure proper
lubrication (Fig. 95).
Camshaft bearing index can be inspected after
in-
stallation by inserting a pencil flashlight in the bear-
ing shell. The camshaft bearing oil hole should be per-
fectly aligned with the drilled oil passage from the
main bearing. Also the Number 4 bearing must index
with the two oil passages to the cylinder heads. If the
camshaft bearing shell oil holes are not in exact align-
ment, remove and reinstall them correctly. Apply Mo-
Par Sealer to the plug and use Tool C-897 to install
a new core hole plug at the rear
of
camshaft. Be sure
this plug does not leak.
