(7) Remove each piston and connecting rod assem-
bly out of the cylinder bore.
NOTE: Be careful not to nick crankshaft journals.
(8) After removal, install bearing cap on the mat-
ing rod.
INSTALLATION
(1) Before installing pistons and connecting rod
assemblies into the bore, ensure that compression
ring gaps are staggered so that neither is in line with
oil ring rail gap (Fig. 58).(2) Before installing the ring compressor, ensure
the oil ring expander ends are butted and the rail
gaps located as shown in (Fig. 58).
(3) Lubricate the piston and rings with clean
engine oil. Position a ring compressor over the piston
and rings, and tighten the compressor (Fig. 59).Be
sure position of rings does not change during
this operation.
(4) Position upper bearing onto connecting rod.
Lubricate bearing with oil.
(5) Install connecting rod bolt protectors (rubber
hose or equivalent) on the connecting rod bolts (Fig.
59).
(6) The pistons are marked with a ªFº located near
the piston pin. Install piston with this mark posi-
tioned to front of engine on both cylinder banks. The
connecting rod oil squirt hole faces the major thrust
(right) side of the engine block (Fig. 60).
(7) Rotate crankshaft until the connecting rod
journal is located in the center of the cylinder bore.
Insert connecting rod and piston into cylinder bore.
Carefully guide connecting rod over the crankshaft
journal (Fig. 59).
(8) Tap the piston down in cylinder bore, using a
hammer handle. At the same time, guide connecting
rod into position on connecting rod journal.
(9) Install lower bearing shell and connecting rod
cap (Fig. 59). Install nuts on cleaned and oiled rod
bolts and tighten to 54 N´m (40 ft. lbs.) PLUS

turn.
(10) Repeat procedure for each piston and connect-
ing rod installation.
(11) Install the cylinder heads. (Refer to 9 -
ENGINE/CYLINDER HEAD - INSTALLATION)
(12) Install the oil pan. (Refer to 9 - ENGINE/LU-
BRICATION/OIL PAN - INSTALLATION)
(13) Fill engine crankcase with proper oil to cor-
rect level.
(14) Connect negative cable to battery.

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. 69). 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 ofPlastigage 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:
a. Shim 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:
a. Support 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. 70). (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. 71) 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.

ance ranges. Use the most appropriate range for
the specifications you are checking.

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. 70).
(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. 71). 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. 72) 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. 72).
(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. 73).
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. 73).
(5) Install each main cap and tighten bolts finger
tight.
