(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 timing chain tensioner. Torque bolts to
24 N·m (210 in. lbs.) torque.
(5) Compress tensioner shoe (Fig. 23) and install a
suitable sized pin to retain shoe for chain installa-
tion.
(6) Place both camshaft sprocket and crankshaft
sprocket on the bench with timing marks on an exact
imaginary center line through both camshaft and
crankshaft bores.
(7) Place timing chain around both sprockets.
(8) Turn crankshaft and camshaft to line up with
keyway location in crankshaft sprocket and in cam-
shaft sprocket.
(9) Lift sprockets and chain (keep sprockets tight
against the chain in position as described).
(10) Slide both sprockets evenly over their respec-
tive shafts and use a straightedge to check alignment
of timing marks (Fig. 24) .
(11) Install the camshaft bolt/cup washer. Tighten
bolt to 68 N·m (50 ft. lbs.) torque.
(12) Measure camshaft end play (Fig. 25). (Refer to
9 - ENGINE - SPECIFICATIONS) for proper clear-
ance. If not within limits, install a new timing chain
tensioner.
(13) Each tappet reused must be installed in the
same position at which it was removed. When cam-
shaft is replaced, all of the tappets must be
replaced.Install hydraulic tappets (Refer to 9 -
ENGINE/ENGINE BLOCK/HYDRAULIC LIFTERS
(CAM IN BLOCK) - INSTALLATION).
(14) Install timing chain cover (Refer to 9 -
ENGINE/VALVE TIMING/TIMING BELT / CHAIN
COVER(S) - INSTALLATION).
(15) Install intake manifold (Refer to 9 - ENGINE/
MANIFOLDS/INTAKE MANIFOLD - INSTALLA-
TION).
(16) Install distributor (Refer to 8 - ELECTRICAL/
IGNITION CONTROL/DISTRIBUTOR - INSTALLA-
TION).
(17) Install cylinder head covers (Refer to 9 -
