AN
CAMSHAFT & BEARINGS (IN BLOCK) (Continued)
INSTALLATION—CAMSHAFT BEARINGS
(1) Inspect the camshaft bearing journals for
uneven wear pattern or finish.
(2) Inspect the camshaft lobes and distributor gear
for wear.
(3) Inspect the camshaft thrust plate for wear. If
the plate shows excessive wear inspect the camshaft
oil pressure relief holes in the rear cam journal. The
relief holes must be clean and free of debris.
CAUTION: Make sure outside diameter of number 1
bearing is clean. Make sure that the bearing is
properly installed in the engine block, align the oil
hole in the bearing with the oil gallery in the bear-
ing bore. Failure to do so will cause inadequate oil
supply for the sprockets and timing chain.
(4) Using special tool 8544 Camshaft Bushing
Remover Installer or equivalent, install new cam-
shaft bearings.
(5) Lubricate the camshaft with Mopar engine oil
supplement, or equivalent.
(6) Install the camshaft (Refer to 9 - ENGINE/EN-
GINE BLOCK/CAMSHAFT
BLOCK) - INSTALLATION).
INSTALLATION—CAMSHAFT
(1) Inspect the cam lobes for wear.
(2) Inspect the bearing journals for uneven wear
pattern or finish.
(3) Inspect the bearings for wear.
(4) Inspect the distributor drive gear for wear.
(5) If the camshaft appears to have been rubbing
against the timing case cover, examine the oil pres-
sure relief holes in the rear cam journal. The oil
pressure relief holes must be free of debris.
(6) Lubricate the camshaft with Mopar
Oil Supplement, or equivalent.
(7) Carefully install the camshaft to prevent dam-
age to the camshaft bearings (Fig. 27).
(8) Turn the tensioner lever to the unlocked (down)
position (Fig. 28).
(9) Pull the tensioner block toward the tensioner
lever to compress the spring. Hold the block and turn
the tensioner lever to the lock position (Fig. 28).
(10) Install the timing chain and sprockets (Refer
to 9 - ENGINE/VALVE TIMING/TIMING BELT/
CHAIN AND SPROCKETS - INSTALLATION).
(11) Release the timing chain tensioner by moving
the lever to the unlock position (Fig. 28).
(12) Install the timing case cover with a replacement
oil seal (Fig. 29) (Refer to 9 - ENGINE/VALVE TIMING/
TIMING BELT / CHAIN COVER(S) - INSTALLATION).
(13) Install the vibration damper (Refer to 9 -
ENGINE/ENGINE BLOCK/VIBRATION DAMPER -
INSTALLATION).
