(5) Install lower main bearings into main bearing
cap/bedplate. Make certain the bearing tabs are
seated into the bedplate slots.
(6) Position the main bearing/bedplate onto the
engine block.
(7) Before installing bolts, lubricate the threads
with clean engine oil, wipe off any excess oil.
(8) Install main bearing bedplate to engine block
bolts 11, 17 and 20 finger tight. Tighten these bolts
down together until the bedplate contacts the cylin-
der block.
(9) To ensure correct thrust bearing alignment,
perform the following steps:
²Step 1: Rotate crankshaft until number 4 piston
is at TDC.
²Step 2: Move crankshaft rearward to limits of
travel.
²Step 3: Then, move crankshaft forward to limits
of travel.
²Step 4: Wedge an appropriate tool between the
rear of the cylinder block(NOT BED PLATE)and
the rear crankshaft counterweight. This will hold the
crankshaft in it's furthest forward position.
²Step 5: Install and tighten bolts (1±10) in
sequence shown in (Fig. 57) to 41 N´m (30 ft. lbs.).
²Step 6: Remove wedge tool used to hold crank-
shaft.
(10) Tighten bolts (1±10) again to 41 N´m (30 ft.
lbs.)PLUS1/4 turn in sequence shown in (Fig. 57).
(11) Install main bearing bedplate to engine block
bolts (11±20), and torque each bolt to 28 N´m (20 ft.
lbs.) in sequence shown in (Fig. 57).
(12) After the main bearing bedplate is installed,
check the crankshaft turning torque. The turning
torque should not exceed 5.6 N´m (50 in. lbs.).

CRANKSHAFT MAIN
BEARINGS
STANDARD PROCEDURE - MAIN BEARING
FITTING
Bearing caps are not interchangeable and should
be marked at removal to insure correct assembly
(Fig. 56). Upper and lower bearing halves are NOT
interchangeable. Lower main bearing halves of 1, 3
and 4 are interchangeable. Upper main bearing
halves of 1, 3 and 4 are interchangeable.
Upper and lower number 2 bearing halves are
flanged to carry the crankshaft thrust loads and are
NOT interchangeable with any other bearing halves
in the engine (Fig. 57). All bearing cap bolts removed
during service procedures are to be cleaned and
lubricated with engine oil before installation. Bearing
shells are available in standard and the following
undersizes: 0.025 mm (0.001 in.) and 0.254 mm
(0.010 in). Never install an undersize bearing that
will reduce clearance below specifications.
CRANKSHAFT BEARING OIL CLEARANCE
Inspect the crankshaft bearing journals. (Refer to 9
- ENGINE/ENGINE BLOCK/CRANKSHAFT -
INSPECTION)
Engine crankshaft bearing clearances can be deter-
mined by use of Plastigage or the equivalent. The fol-
lowing is the recommended procedures for the use of
Plastigage with the engine in the vehicle or engine
on a repair stand.PLASTIGAGE METHODÐENGINE IN-VEHICLE
NOTE: The total clearance of the main bearings can
only be determined with the engine in the vehicle
by removing the weight of the crankshaft. This can
be accomplished by either of two following meth-
ods:
(1) Preferred method:
²Shim the bearings adjacent to the bearing to be
checked in order to remove the clearance between
upper bearing shell and the crankshaft. This can be
accomplished by placing a minimum of 0.254 mm
(0.010 in.) shim (e. g. cardboard, matchbook cover,
etc.) between the bearing shell and the bearing cap
on the adjacent bearings and tightening bolts to
14±20 N´m (10±15 ft. lbs.).
²When checking #1 main bearing shim #2 main
bearing.
²When checking #2 main bearing shim #1 & #3
main bearing.
²When checking #3 main bearing shim #2 & #4
main bearing.
²When checking #4 main bearing shim #3 main
bearing.
NOTE: Remove all shims before reassembling
engine.

(2) Alternative Method:
²Support the weight of the crankshaft with a jack
under the counterweight adjacent to the bearing
being checked.
(3) Remove oil film from surface to be checked.
Plastigage is soluble in oil.
(4) Place a piece of Plastigage across the entire
width of the bearing shell in the cap approximately
6.35 mm (1/4 in.) off center and away from the oil
holes (Fig. 58). (In addition, suspected areas can be
checked by placing the Plastigage in the suspected
area). Torque the bearing cap bolts of the bearing
being checked to the proper specifications.
(5) Remove the bearing cap and compare the width
of the flattened Plastigage (Fig. 59) with the scale
provided on the package. Locate the band closest to
the same width. This band shows the amount of
clearance in thousandths. Differences in readings
between the ends indicate the amount of taper
present. Record all readings taken. (Refer to 9 -
ENGINE - SPECIFICATIONS)Plastigage gener-
ally is accompanied by two scales. One scale is
in inches, the other is a metric scale.
NOTE: Plastigage is available in a variety of clear-
ance ranges. Use the most appropriate range for
the specifications you are checking.PLASTIGAGE METHODÐENGINE OUT-OF-VEHICLE
(1) With engine in the inverted position (crank-
shaft up) and mounted on a repair stand, remove
main journal cap.
(2) Remove oil from journal and bearing shell.
(3) Cut Plastigage to same length as width of the
bearing and place it in parallel with the journal axis
(Fig. 58).
(4) Carefully install the main bearing cap and
tighten the bolts to specified torque.
CAUTION: Do not rotate crankshaft or the Plasti-
gage will be smeared.
(5) Carefully remove the bearing cap and measure
the width of the Plastigage at the widest part using
the scale on the Plastigage package (Fig. 59). Refer
to Engine Specifications for proper clearances (Refer
to 9 - ENGINE - SPECIFICATIONS). If the clearance
exceeds the specified limits, replace the main bear-
ing(s) with the appropriate size, and if necessary,
have the crankshaft machined to next undersize.
REMOVAL - CRANKSHAFT MAIN BEARINGS
(1) Remove the oil pan. (Refer to 9 - ENGINE/LU-
BRICATION/OIL PAN - REMOVAL)
(2) Identify main bearing caps before removal.
(3) Remove bearing caps one at a time. Remove
upper half of bearing by inserting Special Main Bear-
ing Tool C-3059 (Fig. 60) into the oil hole of crank-
shaft.
(4) Slowly rotate crankshaft clockwise, forcing out
upper half of bearing shell.

INSTALLATION - CRANKSHAFT MAIN
BEARINGS
NOTE: One main bearing should be selectively fit-
ted while all other main bearing caps are properly
tightened.
(1) For main bearing fitting procedure, (Refer to 9
- ENGINE/ENGINE BLOCK/CRANKSHAFT MAIN
BEARINGS - STANDARD PROCEDURE)
(2) Start bearing in place, and insert Main Bearing
Tool C-3059 into oil hole of crankshaft (Fig. 60).
(3) Slowly rotate crankshaft counterclockwise slid-
ing the bearing into position. Remove Special Main
Bearing Tool C-3059.
(4) Inspect main cap bolts for stretching (Fig. 61).
Replace bolts that are stretched.
NOTE: The main cap bolts should be examined
before reuse. Bolt stretch can be checked by hold-
ing a scale or straight edge against the threads. If
all the threads do not contact the scale the bolt
must be replaced (Fig. 61).
(5) Install each main cap and tighten bolts finger
tight.
(6) Tighten number 1, 3 and 4 main cap bolts to 41
N´m + 1/4 Turn (30 ft. lbs.+ 1/4 Turn).
(7) Rotate the crankshaft until the number 6 pis-
ton is at TDC.
(8) To ensure correct thrust bearing alignment the
following procedure must be done:
²Move crankshaft all the way to the rear of its
travel.
²Then, move crankshaft all the way to the front
of its travel.
²Wedge an appropriate tool between the rear of
the cylinder block and rear crankshaft counter-
weight. This will hold the crankshaft in it's most for-
ward position.²Tighten the #2 Thrust Bearing cap bolts to 41
N´m + 1/4 Turn (30 ft. lbs.+ 1/4 Turn). Remove the
holding tool.
(9) Install oil pan. (Refer to 9 - ENGINE/LUBRI-
CATION/OIL PAN - INSTALLATION)
(10) Fill engine crankcase with proper oil to cor-
rect level.

(.0025-.0032 in.).
(6) Make sure the weight of the pistons does not
differ by more than 5 g.
CONNECTING RODS
(1) Assemble bearing shells and bearing caps to
their respective connecting rods ensuring that the
serrations on the cap and reference marks are
aligned.
(2) Tighten bearing cap bolts to 29 N´m (21 ft. lbs.)
plus 60É.
(3) Check and record internal diameter of crank
end of connecting rod.
NOTE: When changing connecting rods, all four
must have the same weight and be stamped with
the same number. Replacement connecting rods
will only be supplied in sets of four.
Connecting rods are supplied in sets of four since
they all must be of the same weight category. Max
allowable weight difference is 18 gr.
NOTE: On one side of the big end of the con-rod
there is a two-digit number which refers to the
weight category. On the other side of the big end
there is a four digit number on both the rod and the
cap. These numbers must both face the injection
pump side of the block. Lightly heat the piston in
oven. Insert piston pin in position and secure it
with provided snap rings.
The Four digit numbers marked on con rod
big end and rod cap must be on the same side
as the injection pump.After having coated threads
with Molyguard, tighten con rod bolts to 29 N´m (21
ft. lbs.) plus 60É.
