INSTALLATION—BEARING
(1) Install new camshaft bearings with Camshaft
Bearing Remover/Installer Tool C-3132-A by sliding
the new camshaft bearing shell over proper adapter.
(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.
NSTALLATION .
(1) Lubricate camshaft lobes and camshaft bearing
journals. Using a long bolt, insert the camshaft into
the 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 k m (500 miles).
Drain at the next normal oil change.
(2) Install camshaft thrust plate. Tighten the torx
bolts to 22 N-m (16 ft. lbs.) torque.
(3) Check camshaft end play. The end play should
be 0.051-0.152 mm (0.002-0.006 inch) with a new
thrust plate and up to 0.254 mm (0.010 inch) with a
used thrust plate. If not within these limits install a
new thrust plate.
(4) Line up key with keyway in sprocket, press on
crankshaft timing sprocket, use tools C-3688, C-3718
and MB990799, to seat sprocket against crankshaft
shoulder (Fig. 18).
(5) Align timing mark on crankshaft sprocket with
center line of crankshaft and camshaft.
(6) Put chain on camshaft sprocket.
(7) Take chain and camshaft sprocket and align
mark with centerline of crankshaft and camshaft in­
stall camshaft sprocket and chain to camshaft.
