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 pis-
ton pin grades can be selected. (Only “0” grade is available.)
 No second grade mark is available on piston.
HOW TO SELECT CONNECTING ROD BEARING
When New Connecting Rod and Crankshaft are Used:
Check pin diameter grade (“0”, “1” or “2”) on front of crankshaft, and
select connecting rod bearing of the same grade.
NOTE:
There is no grading for connecting rod big end diameter.
When Crankshaft and Connecting Rod are Reused:
1. Measure the connecting rod big end diameter. Refer to EM-256, "Inspection After Disassembly".
2. Make sure that the connecting rod big end diameter is within the standard value.
3. Measure the crankshaft pin journal diameter. Refer to EM-256, "
Inspection After Disassembly".
4. Determine the grade of crankshaft pin diameter grade by corresponding to the measured dimension in
“Crankshaft pin journal diameter” column of “Connecting Rod Bearing Selection Table”.
5. Select connecting rod bearing of the same grade.

Under Size Bearings Usage Guide
 When the specified connecting rod bearing oil clearance is not obtained with standard size connecting rod bearings, use undersize (US) bearings.
 When using undersize (US) bearing, measure the connecting rod bearing inner diameter with bearing
installed, and grind crankshaft pin so that the c onnecting rod bearing oil clearance satisfies the standard.

Use Undersize Bearing Usage Guide
 When the specified main bearing oil clearance is not obtained with standard size main bearings, use under-
side (US) bearing.
 When using undersize (US) bearing, measure the main bearing inner diameter with bearing installed, and
grind main journal so that the main bearing oil clearance satisfies the standard.
