Revision: 2006 December 2006 FX35/FX45

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)

Oil ring : 0.20 - 0.50 mm (0.0079 - 0.0197 in)
Limit:


Top ring : 0.56 mm (0.0220 in)


2nd ring : 0.56 mm (0.0220 in)
Oil ring : 0.96 mm (0.0378 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.
Factory installed parts grading:

Service parts apply only to grade “0”.

CYLINDER BLOCK DISTORTION

Using scraper, remove gasket on the cylinder block surface, and also remove engine oil, scale, carbon, or
other contamination.
CAUTION:
Be careful not to allow gasket flakes to enter engine oil or engine coolant passages. Standard : 21.989 - 22.001 mm (0.8657 - 0.8662 in)
