PISTON AND CONNECTING ROD

TSB Revision

ENGINE OVERHAUL <3.0L ENGINE>

>>E<< CONNECTING ROD CAP INSTALLATION
1. Mate the correct bearing cap with the correct connecting rod

by checking with the alignment marks marked during
disassembly. If a new connecting rod is used which has no
alignment mark, position the notches for locking the bearing
on the same side.

2. Check if the thrust clearance in the connecting rod big end is

correct.

Standard value: 0.10

−

0.25 mm (0.004

−

0.009 inch)

Limit: 0.4 mm (0.02 inch)

INSPECTION

M1113008500042

PISTON
Replace the piston if scratches or seizure is evident on its
surfaces (especially the thrust surface). Replace the piston if it
is cracked.

PISTON PIN
1. Insert the piston pin into the piston pin hole with your thumb.

You should feel a slight resistance. Replace the piston pin if
it can be easily inserted or there is an excessive play.

2. The piston and piston pin must be replaced as an assembly.

PISTON RING
1. Check the piston ring for damage, excessive wear, and

breakage. Replace if defects are evident. If the piston has
been replaced, the piston rings must also be replaced.

2. Check for clearance between the piston ring and ring

groove. If it exceeds the limit, replace the ring or piston, or
both.

Standard value:

Number 1 0.03

−

0.07 mm (0.0012

−

0.0027 inch)

Number 2 0.02

−

0.06 mm (0.0008

−

0.0023 inch)

Limit: 0.1 mm (0.003 inch)

3. Insert the piston ring into the cylinder bore. Force the ring

down with a piston, the piston crown being in contact with
the ring, to correctly position it at right angles to the cylinder
wall. Then, measure the end gap with a feeler gauge.
If the ring gap is excessive, replace the piston ring.

Standard value:

Number 1: 0.30

Number 1, Number 2: 0.8 mm (0.03 inch)
Oil: 1.0 mm (0.03 inch)

CRANKSHAFT PIN OIL CLEARANCE (PLASTIC GAUGING
MATERIAL METHOD)
1. Remove oil from the crankshaft pin and the connecting rod

bearing.

2. Cut plastic gauging material to the same length as the width

of the bearing and place it on the pin in parallel with its axis.

3. Install the connecting rod cap carefully and tighten the nuts

to the specified torque.

4. Carefully remove the connecting rod cap.

5. Measure the width of the plastic gauging material at its

widest part by using a scale printed on the plastic gauging
material package.

Standard value: 0.02

−

0.05 mm (0.0008

−

0.0019 inch)

Limit: 0.1 mm (0.003 inch)

CAUTION

On the flexible flywheel equipped engines, do not remove any of the bolts "A" of the flywheel shown
in the illustration. The balance of the flexible flywheel is adjusted in an assembled condition.
Removing the bolt, therefore, can cause the flexible flywheel to be out of balance and result in
damage.
