When installing, align the connecting rod bearing stopper pro-
trusion with the cutout of connecting rod and connecting rod
bearing cap to install.

Ensure the oil holes on connecting rod and that on the corre-
sponding bearing are aligned.
13. Install piston and connecting rod assembly to crankshaft.

Position the crankshaft pin corresponding to connecting rod to be installed onto the bottom dead center.

Apply engine oil sufficiently to the cylinder bore, piston and crankshaft pin journal.

Match the cylinder position with the cylinder No. on connecting rod to install.

Be sure that front mark on piston head is facing front of engine.

Using piston ring compressor [SST: EM03470000 (J8037)],
install piston with the front mark on the piston head facing the
front of engine.
CAUTION:
Be careful not to damage cylinder wall and crankshaft pin,
resulting from an interference of the connecting rod big
end.
14. Install connecting rod bearing cap.

Match the stamped cylinder number marks on connecting rod
with those on cap to install.
15. Tighten connecting rod nuts as follows:
a. Apply new engine oil to the threads and seats of connecting rod bolts and nuts.
b. Tighten connecting rod nuts.
c. Then tighten all connecting rod nuts 60 degrees clockwise. (Angle tightening)
CAUTION:
Use angle wrench (SST) to check tightening angle. Do not
make judgment by visual inspection.

After tightening connecting rod nuts, make sure that crank-
shaft rotates smoothly.

Check the connecting rod side clearance. Refer to EM-265,
"CONNECTING ROD SIDE CLEARANCE" .

When replacing piston and piston pin assembly, refer to EM-259, "HOW TO SELECT PISTON" .
NOTE:

Piston is available together with piston pin as assembly.

Piston pin (piston pin hole) grade is provided only for the parts installed at the plant. For service parts,
no piston pin grades can be selected. (Only “0” grade is available.)
PISTON RING SIDE CLEARANCE

Measure the side clearance of piston ring and piston ring groove
with feeler gauge.

If the measured value exceeds the limit, replace piston ring, and measure again. If it still exceeds the limit,
replace piston also.
PISTON RING END GAP

Make sure that the cylinder bore inner diameter is within the
specification. Refer to EM-269, "
Cylinder Bore Inner Diameter" .

Lubricate with new engine oil to piston and piston ring, and then
insert piston ring until middle of cylinder with piston, and mea-
sure the piston ring end gap with feeler gauge.

If the measured value exceeds the limit, replace piston ring, and measure again. If it still exceeds the limit,
re-bore cylinder and use oversize piston and piston rings. Standard:
Top ring : 0.045 - 0.080 mm (0.0018 - 0.0031 in)
2nd ring : 0.030 - 0.070 mm (0.0012 - 0.0028 in)
Oil ring : 0.065 - 0.135 mm (0.0026 - 0.0053 in)
Limit:

Top ring : 0.11 mm (0.0043 in)

2nd ring : 0.1 mm (0.004 in)

Piston Pin Outer Diameter
Measure the outer diameter of piston pin with micrometer.
Connecting Rod Bushing Oil Clearance
(Connecting rod bushing oil clearance) = (Connecting rod bushing inner diameter) – (Piston pin outer diame-
ter)

If the calculated value exceeds the limit, replace connecting rod assembly and/or piston and piston pin
assembly.

If replacing piston and piston pin assembly, refer to EM-259, "HOW TO SELECT PISTON" .

If replacing connecting rod assembly, refer to EM-272, "CON-
NECTING ROD BEARING OIL CLEARANCE" to select the con-
necting rod bearing.

PRECAUTIONS
Revision: 2006 July 2007 FX35/FX45
PRECAUTIONSPFP:00001
CautionNES000FK

When installing rubber bushings, final tightening must be carried out under unladen conditions with tires
on ground. Oil will shorten the life of rubber bushings. Be sure to wipe off any spilled oil.

Unladen conditions mean that fuel, engine coolant and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.

After servicing suspension parts, be sure to check wheel alignment.

Caulking nuts are not reusable. Always use new ones when installing. Since new caulking nuts are pre-
oiled, tighten as they are.

Avoid burden to front cross bar.
