HOW TO SELECT CONNECTING ROD BEARING
When Using New Crankshaft and Connecting Rod
1. Identify the pin diameter grade (No. 0, 1, or 2) on front surface of
crankshaft.
2. Select connecting rod bearings of the same grade.
NOTE:
There is no grading for the inner diameter of the big end of the
connecting rod.
When Re-using the Removed Crankshaft and Connecting Rod
1. Measure the inner diameter of the big end of connecting rod and make sure it is within the specified
range. Refer to EM-228, "
CONNECTING ROD BIG END INNER DIAMETER" .
2. Measure the outer diameter of the crankshaft pin. Refer to EM-231, "
CRANKSHAFT PIN OUTER DIAME-
TER" .
3. Determine the crankshaft pin grade by comparing the measurement with the values under the column
“Crankshaft pin outer diameter” in “Selection Table of connecting Rod Bearing”.
4. Choose bearings of the same grade.

Under Size Bearing Usage
If bearing clearance is out of the specifications for connecting rod bearings in standard size, use under
size bearings.
When using under size bearings, measure bearing inner diameter with bearing installed, and grind crank-
shaft pins to adjust clearance to specification.
