If the crankshaft is within limits, replace the bear-
ing. If the crankshaft is out of limits, grind the
crankshaft to the next smaller size and use oversize
rod bearings.
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 -
STANDARD PROCEDURE).
(14) Connect battery negative cables.
(15) Start engine and check for oil leaks.

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,

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.

²If a new cylinder block and/or crankshaft is used,
the piston grading procedureMUST
be performed to
determine the proper piston grade for each cylinder.
(1) Install any of the original connecting rod and
piston assemblies into the No.1 cylinder. DO NOT
install the piston rings.
(2) Install the upper bearing shell in the connect-
ing rod with the tang of the bearing in the slot of the
connecting rod. The connecting rod bearing shell
must be installed in the original connecting rod and
cap. Use clean lubricating oil to coat the inside diam-
eter of the connecting rod bearing shell.
(3) Install the bearing shell in the connecting rod
cap with the tang of the bearing in the slot to the
cap. Use clean lubricating oil to coat the inside diam-
eter of the bearing shell.(4) The four digit number stamped on the connect-
ing rod and cap at the parting line must match and
be installed on the oil cooler side of the engine.
Install the connecting rod cap and cap screws.
Tighten the cap screws to 35 N´m (26 ft. lbs.) torque.
(5) Use a fine grit stone to remove any burrs from
the cylinder block head deck. Zero the dial indicator
to the cylinder block head deck.
(6) Move the dial indicator directly over the piston
pin to eliminate any side-to-side movement.
(7) Rotate the crankshaft to top dead center
(TDC). Rotate the crankshaft clockwise and counter-
clockwise to find the highest dial indicator reading.
Record the reading.
(8)
Remove the piston and connecting rod assembly
from the No.1 cylinder and install the assembly into the
No.2 cylinder. Repeat the procedure for every cylinder
using the same piston and connecting rod assembly.
(9)Determine the grade of the piston being used by
referring to the Piston Protrusion Chart below. Four
digits on top of the piston can be cross referenced to a
DaimlerChrysler part number for replacement (Fig.
126). If the number on the piston cannot be seen, mea-
sure from the top of the piston to the top of the piston
pin to see what grade piston is used (Fig. 127).
NOTE: NEVER INTERMIX PISTONS FROM ONE
ENGINE APPLICATION TO ANOTHER ENGINE
APPLICATION. SEVER DRIVEABILITY CONCERNS
MAY RESULT.

PISTON & CONNECTING ROD (Continued)

INSTALLATION
(1) Lubricate the cylinder bores with clean engine
oil.
(2) Generously lubricate the rings and piston
skirts with clean engine oil.
(3) Compress the rings using a piston ring com-
pressor tool (Fig. 133). If using a strap-type ring com-
pressor, make sure the inside end of the strap does
not hook on a ring gap and break the ring.
(4) Bar the crankshaft so the rod journal for the
piston to be installed is at BDC (Bottom Dead Cen-
ter) - (Fig. 134).
(5) Be sure the mark you made on the piston and
the numbers on the rod and cap are oriented as illus-
trated.
(6) Position the piston and rod assembly into the
cylinder bore with the mark you made on the piston
towards the front of the cylinder block. In this posi-
tion the numbers on the connecting rod should be
facing the oil cooler side of the engine, and the rod
bolt holes toward the camshaft. Use care when you
install the piston and connecting rod so the cylinder
bore is not damaged.
(7) Push the piston into the bore until the top of
the piston is approximately 50 mm (2 inch) below thetop of the block. Carefully pull the connecting rod
onto the crankshaft journal.
(8) Use clean engine oil to lubricate the threads
and under the heads of the connecting rod bolts.
(9) The number stamped on the rod cap at the
parting line must match and be installed towards the
oil cooler side of the engine (Fig. 135).
(10) Install the rod cap and bolts to the connecting
rod. Tighten the connecting rod and bolt evenly in 3
steps.
²Tighten the bolts to 35 N´m (26 ft. lbs.) torque.
²Tighten the bolts to 70 N´m (51 ft. lbs.) torque.
²Tighten the bolts to 100 N´m (73 ft. lbs.) torque.
(11) The crankshaft must rotate freely. Check for
freedom of rotation as the caps are installed. If the
crankshaft does not rotate freely, check the installa-
tion of the rod bearing and the bearing size.
(12) Measure the side clearance between the con-
necting rod and the crankshaft (Fig. 136). DO NOT
measure the clearance between the cap and crank-
shaft.
