Inspect the push rod ball and socket for signs of
scoring. Check for cracks where the ball and the
socket are pressed into the tube (Fig. 65).
Roll the push rod on a flat work surface with the
socket end hanging off the edge (Fig. 66). Replace
any push rod that appears to be bent.

(1) Apply a coating of Loctitet640 Adhesive to the
backside of the new bushing. Avoid getting adhesive
in the oil hole.
(2) Use a universal cam bushing installation tool
and install the bushing so that it is even with the
front face of the cylinder block. The oil hole must be
aligned. A 3.2 mm (0.128 inch) diameter rod must be

CRANKSHAFT
DESCRIPTION
The crankshaft (Fig. 100) is a forged steel, inte-
grally balanced unit. It is supported by seven main
bearings, with position number six designated as the
thrust journal. The crankshaft is held in place by
main caps and 12 mm capscrews. The crankshaft
also has internal cross drillings to supply the con-
necting rods with engine oil.

INSTALLATION
(1)Clean cover and housing gasket mating surfaces.
Use a suitable scraper and be careful not to damage the
gear housing surface, since it is aluminum. Remove any
old sealer from the oil seal bore. Thoroughly clean the
front seal area of the crankshaft. The seal lip and the
sealing surface on the crankshaft must be free from all
oil residue to prevent seal leaks.
(2) Inspect the gear housing and cover for cracks
and replace if necessary. Carefully straighten any
bends or imperfections in the gear cover with a ball-
peen hammer on a flat surface. Inspect the crank-
shaft front journal for any grooves or nicks that
would affect the integrity of the new seal.
(3) Apply a bead of MopartStud & Bearing Mount
to the outside diameter of the seal. Do not lubricate
the inside diameter of the new seal.
(4)
With the cover supported by wood blocks, install
the seal into the rear of the cover using crankshaft seal
installer Special Tool 8281 and driver handle C-4171
(Fig. 106). Strike the driver handle until the installation
tool bottoms out on the inside of the cover.
(5) Install the plastic seal pilot (provided with seal
kit) into the crankshaft seal.
(6) Apply a bead of MopartSilicone Rubber Adhe-
sive Sealant or equivalent to the gear housing cover
sealing surface.
(7) Install the cover to the gear housing, aligning
the seal pilot with the nose of the crankshaft (Fig.
107).
(8) Install the cover bolts and tighten to 24 N´m
(18 ft. lbs.) torque. Remove pilot tool.
(9) Install the crankshaft damper (Fig. 104) and
torque the bolts to 125 N´m (92 ft. lbs.). Use theengine barring tool to keep the engine from rotating
during tightening operation.
(10) Install the fan support/hub assembly (Fig.
103) and torque bolts to 24 N´m (18 ft. lbs.).
(11) Install cooling fan (Refer to 7 - COOLING/EN-
GINE/RADIATOR FAN - INSTALLATION).
(12) Install the accessory drive belt (Refer to 7 -
COOLING/ACCESSORY DRIVE/DRIVE BELTS -
INSTALLATION).
(13) Refill cooling system (Refer to 7 - COOLING -

INSTALLATION
CAUTION: The seal lip and the sealing surface on
the crankshaft must be free from all oil residue to
prevent seal leaks. The crankshaft and seal sur-
faces must be completely dry when the seal is
installed. Use a soap and water solution on outside
diameter of seal to ease assembly.

solvent and dry with a clean shop towel or com-
pressed air. Wipe the inside bore of the crankshaft
seal retainer with a clean shop towel.
(2) Inspect the crankshaft journal for gouges,
nicks, or other imperfections. If the seal groove in the
crankshaft is excessively deep, install the new seal
1/8º deeper into the retainer bore, or obtain a crank-shaft wear sleeve that is available in the aftermar-
ket.
(3) Install the seal pilot, provided in the replace-
ment kit, onto the crankshaft.
(4) Using the provided alignment/installation tool,
start the seal over the pilot and into the retainer by
hand.
(5) Using a ball peen hammer, strike the tool at
the 12, 3, 6, and 9 o'clock positions until the align-
ment tool bottoms out on the retainer (Fig. 109).
(6) Remove the seal pilot.
(7) Install the flywheel or converter drive plate.
