HOW TO SELECT CONNECTING ROD BEARING
When Using a New Crankshaft and Connecting Rod
1. Identify the pin diameter grade (No. 0, 1, or 2) on front surface of
crankshaft.
2. Select the connecting rod bearings of the same grade.
●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 the connecting rod and make sure it is within the specified
range.
2. Measure the outer diameter of the crankshaft pin.
3. Determine the crankshaft pin grade by comparing the measurement with the values under the column
“Crankshaft pin outer diameter” of the table below.
4. Choose the bearings of the same grade.
