(2) Position rear bearing in the tool. Install horse­
shoe lock and by reversing removal procedure, care­
fully drive bearing shell into place.
(3) Install remaining bearings in the same manner.
Bearings must be carefully aligned to bring oil holes
into full register with oil passages from the main
bearing. If the camshaft bearing shell oil holes are
not in exact alignment, remove and install them cor­
rectly. Install a new core hole plug at the rear of
camshaft. Be sure this plug does not leak.
INSTALLATION
(1) Lubricate camshaft lobes and camshaft bearing
journals and insert the camshaft to within 51 mm (2
inches) of its final position in cylinder block.
Whenever an engine has been rebuilt, a new
camshaft and/or new tappets installed, add 1
pint of Mopar® Crankcase Conditioner, or
equivalent. The oil mixture should be left in en­
gine for a minimum of 805 km (500 miles).
Drain at the next normal oil change.
(2) Install Camshaft Gear Installer Tool C-3509
with tongue back of distributor drive gear (Fig. 12).

Position)
(3) Hold tool in position with a distributor lock-
plate bolt. This tool will restrict camshaft from being
pushed in too far and prevent knocking out the welch
plug in rear of cylinder block. Tool should remain
installed until the camshaft and crankshaft
sprockets and timing chain have been installed.
(4) Install camshaft thrust plate and chain oil tab.
Make sure tang enters lower right hole in
thrust plate. Tighten bolts to 24 N-m (210 in. lbs.)
torque. Top edge of tab should be flat against thrust
plate in order to catch oil for chain lubrication.
(5) Place both camshaft sprocket and crankshaft
sprocket on the bench with timing marks on exact
imaginary center line through both camshaft and
crankshaft bores.
(6) Place timing chain around both sprockets.
(7) Turn crankshaft and camshaft to line up with
keyway location in crankshaft sprocket and in cam­
shaft sprocket.
