(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.
(8) Lift sprockets and chain (keep sprockets tight
against the chain in position as described).
(9) Slide both sprockets evenly over their respec-
tive shafts and use a straightedge to check alignment
of timing marks (Fig. 61).
(10) Install the camshaft bolt/cup washer. Tighten
bolt to 68 N´m (50 ft. lbs.) torque.
(11) Measure camshaft end play. Refer to Specifica-
tions for proper clearance. If not within limits install
a new thrust plate.
(12) Each tappet reused must be installed in the
same position from which it was removed.When
camshaft is replaced, all of the tappets must be
replaced.
(13) Install distributor and distributor drive shaft.
(14) Install push rods and tappets.
(15) Install rocker arms.
(16) Install timing case cover.
(17) Install cylinder head covers.
(18) Install intake manifold.
(19) Install the engine cover.
(20) Install the A/C Condenser (if equipped)
(21) Install the radiator. Refer to Group 7, Cooling

REMOVAL
NOTE: This procedure requires that the engine is
removed from the vehicle.
(1) With engine completely disassembled, drive out
rear cam bearing core plug.
(2) Install proper size adapters and horseshoe
washers (part of Camshaft Bearing Remover/Installer
Tool C-3132-A) at back of each bearing shell. Drive
out bearing shells (Fig. 62).
INSTALLATION
(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 man-
ner. 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
correctly. Install a new core hole plug at the rear of
camshaft.Be sure this plug does not leak.

REMOVAL
(1) Remove distributor, refer to Group 8D, Ignition
Systems for the proper procedure.
(2) Remove the intake manifold. Refer to Intake
Manifold in this section for correct procedure.
(3) Insert Distributor Drive Shaft Bushing Puller
