Tap the main bearing cap into place with a
brass or leather mallet. Then install the bolts.
Tig h ten
• Bolts to specifications, in the following
sequence:
• Inner bolts: 150 N-m (110 ft. lbs.).
• Outer bolts: 135 N-m (100 ft. lbs.).
• Re-tighten all bolts in the same
sequence.
6. Numbers 1, 2, and 4 main bearing caps and bolts.
• Bolts to specifications. Refer to step 5.
7. Number 3 (center) main bearing cap and bolts.
Tighten the bolts temporarily to 14 N-m (10 ft. lbs.).
M easure (Figure 33)
Crankshaft end play, as follows:
• Tap the end of the crankshaft first rearward
then forward with a lead hammer. This will line
up the main bearing and crankshaft thrust
surfaces.
• T ig h te n th e m ain b e a rin g ca p b o lts to
specifications. Refer to step 5.
• With the crankshaft forced forward, measure
at the front end of the number 3 main bearing
with a feeler gage (figure 33). The proper
clearance is 0.10-0.25 mm.
Inspect
Crankshaft for binding. Try turning the crankshaft to
check for binding. If the crankshaft does not turn
freely, loosen the main bearing cap bolts, one pair at
a time, until the tight bearing is located. Burrs on the
bearing cap, foreign matter between the insert and
the block or the bearing cap, or a faulty insert could
cause a lack of clearance at the bearing.

• Bolts (141) to 90 N-m (65 ft. lbs.).
CONNECTING ROD AND
PISTON INSTALLATION
CONNECTING ROD BEARING SELECTION
Connecting rod bearings are of the precision insert type
and do not use shims for adjustment. DO NOT FILE
RODS OR ROD CAPS. If clearances are excessive install
a new bearing. Service bearings are available in standard
size and 0.026 mm (0.001-inch) undersizes.
Selective fitting of both rod and main bearing inserts is
necessary to obtain close tolerances. For this reason you
may use, for example, one half of a standard insert with

B. Second Compression Ring Gap
C. Centerline Of Piston Pin
D. Oil Control Ring Gap
E. Top Compression Ring Gap

one half of a 0.026 mm (0.001-inch) undersize insert which
will decrease the clearance 0.013 mm (0.0005-inch) from
using a full standard bearing.

oversize connecting rods are stamped “ O.S.” on the cap’s
lower end.

Tool Required:
J 8037 Ring Compressor
Make sure the cylinder walls are clean. Lubricate
the cylinder wall lightly with engine oil.
Make sure the piston is installed in the matching
cylinder. Install new pistons in the cylinders for
which they were fitted. Install used pistons in the
cylinder from which they were removed.
Connecting rod bearings.
• Be certain that the bearings are the proper
size.
• Install the bearings in the connecting rod and
connecting rod cap.
Piston and connecting rod to the proper bore.
• With the connecting rod cap rmeoved, install
two short pieces of 10 mm (3/s-inch) hose onto
the connecting rod studs.
• Locate the piston ring end gaps as shown in
figure 34. Lubricate the piston and rings with
engine oil.
