Piston Pin Outer Diameter
Measure the outer diameter of piston pin with a 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-135, "HOW TO SELECT PISTON" .
If replacing connecting rod assembly, refer to EM-146, "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 a 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)
