REMOVAL
(1) Remove crankshaft rear oil seal and oil pan.
Refer to procedure outlined in this section.
(2) Remove seal retainer attaching screws.
(3) Remove seal retainer (Fig. 85).
NOTE: Seal
retainer
gasket
is
bonded
to
the

assembly if gasket is torn or damaged.
(2) Install seal retainer to block, but do not tighten
attaching screws at this time.
NOTE: The following steps must be performed to
prevent oil leaks at sealing joints.
(3) Attach Special Tools 8225 to pan rail using the
oil pan fasteners.
NOTE: Make sure that the marking “3.2/3.5L” on
Special Tools 8225, is facing towards the cylinder
block pan rail surface (notch on tool is towards the
seal retainer).
(4) While applying firm pressure to the seal
retainer against Special Tools 8225 (Fig. 86), tighten

CRANKSHAFT MAIN BEARINGS
Bearing caps are not interchangeable and should
be marked at removal to insure correct assembly.
(Fig. 87) Upper and lower bearing halves are NOT
interchangeable. Lower main bearing halves of 1, 2, 3
and 4 are interchangeable. Upper main bearing
halves of 1, 2, 3, and 4 are interchangeable.
CRANKSHAFT MAIN JOURNALS
The crankshaft journals should be checked for
excessive wear, taper and scoring. Limits of taper or
out-of-round on any crankshaft journals should be
held to 0.025 mm (0.001 in.). Journal grinding should
not exceed 0.305 mm (0.012 inch.) under the stan-
dard journal diameter. DO NOT grind thrust faces of
Number 2 main bearing. DO NOT nick crank pin or
bearing fillets. After grinding, remove rough edges
from crankshaft oil holes and clean out all passages.
CAUTION:
With a forged steel crankshaft it is
important that the final paper or cloth polish after
any journal regrind be in the same direction as nor-
mal rotation in the engine.
The crankshaft thrust is controlled with thrust
washers located at the upper No. 2 main bearing
bulk head (Fig. 88). All bearing cap bolts removed
during service procedures are to be cleaned and oiled
before installation. Bearing shells are available in
standard and the following undersize: 0.025 mm
(0.001 in.) and 0.254 mm (0.010 in.). Never install an
undersize bearing that will reduce clearance below
specifications.
REMOVAL
(1) Remove oil pan, pick-up tube, and windage
tray. Refer to procedures outlined in this section.
Identify bearing caps before removal.
(2) Remove bearing caps one at a time. Remove
upper half of bearing by inserting Special Main Bear-
ing Tool C-3059 (Fig. 89) into the oil hole of crank-
shaft.

(3) Slowly rotate crankshaft clockwise, forcing out
upper half of bearing shell.
INSTALLATION
CAUTION: Main bearings are select fit. Refer to
Crankshaft Main Bearing Fitting in this section for
proper bearing selection.
NOTE:
Only one main bearing should be selec-
tively fitted while all other main bearing caps are
properly tightened.
When installing a new upper bearing shell, slightly
chamfer the sharp edges from the plain side.
(1) Lubricate main bearing with clean engine oil.
(2) Start bearing in place, and insert Main Bearing
Tool C-3059 into oil hole of crankshaft (Fig. 89).
(3) Slowly rotate crankshaft counterclockwise slid-
ing the bearing into position. Remove Special Main
Bearing Tool C-3059.
NOTE: Lubricate
main
bearing
cap
bolts
with
engine oil before installation.
(4) Lubricate and install lower bearing half and
main cap Tighten bolts finger tight.
(5) For installing thrust washers at the No. 2 main
bearing location, use the following procedure:
a.
Move crankshaft forward to limit of travel.
Lubricate and install the front thrust washer by roll-
ing the washer onto the machined shelf between the
No. 2 upper main bulk head and crankshaft thrust
surface (Fig. 90).
b.
Move crankshaft rearward to limit of travel.
Lubricate and install the rear thrust washer by roll-
ing the washer onto the machined shelf between the
No. 2 upper main bulk head and crankshaft thrust
surface.
The main bearing cap bolts must be tightened in
the proper sequence. First the inner main cap bolts,
secondly the windage tray bolts, lastly the main cap
tie (horizontal) bolts.
(6) Install the inside main bearing cap bolts and
tighten to 20 N·m + 1/4 turn (15 ft. lbs. + 1/4 turn).
(7) Measure crankshaft end play. Refer to Service
Procedures in this section.
(8) Install windage tray. Lubricate bolts with
engine oil and tighten to 27 N·m + 1/4 turn (20 ft.
lbs. + 1/4 turn).
(9) Install the main cap tie (horizontal) bolts and
tighten to 28 N·m (250 in. lbs.).
(10) Install oil pump pick-up tube and oil pan.
OIL FILTER
NOTE:
When servicing the oil filter, avoid deform-
ing the filter can. Install the remove/install tool band
strap against the base lock seam. The lock seam
joining the can to the base is reinforced by the
base plate.
(1) Using Tool C-4065, unscrew filter from base
and discard (Fig. 91).
(2) Wipe base clean, then inspect gasket contact
surface.
(3) Lubricate gasket of new filter with clean
engine oil.
(4) Install and tighten filter to 20 N·m (15 ft. lbs.)
of torque after gasket contacts base. Use filter
wrench if necessary.
(5) Start engine and check for leaks.

damper. Refer to procedure outline in this section.
(9) Install the accessory drive belts and fan mod-
ule. Refer to Group 07, Accessory Drive System for
procedure.

PISTON AND CONNECTING ROD
REMOVAL
(1) Remove top ridge of cylinder bores with a reli-
able ridge reamer before removing pistons from cyl-
inder block. Be sure to keep tops of pistons
covered during this operation. Pistons and con-
necting rods must be removed from top of cyl-
inder
block.
When
removing
piston
and
connecting rod assemblies from the engine,
rotate crankshaft so that each connecting rod
is centered in cylinder bore.
(2) Inspect connecting rods and connecting rod
caps for cylinder identification. Identify them if nec-
essary (Fig. 93).
(3) Remove connecting rod cap. Install protectors
on connecting rod bolts (Fig. 94). Push each piston
and rod assembly out of cylinder bore.
