Connecting Rod Large End Bore

Tighten the bolts to specification, then measure the bore in two directions. The difference is the connecting rod bore out-of-round. Verify the out-of-round is within specification.
- Refer to the appropriate ENGINE article for the procedure.
- If out of specification, install new components as necessary.
