Connecting Rod Bearings
- Remove oil pan as previously described.
- Disconnect two connecting rods at a time from crankshaft. Inspect bearing and crankpin journals. While rotating crankshaft to bring rod journals to bottom, it is necessary to reconnect rods to crankshaft.
- If rod bearings are chipped or scored, they must be replaced. If bearings appear satisfactory, use Plastigage method to check clearance.
- If crankpin journals are scored or ridged, crankshaft has to be replaced. Minor imperfections may be eliminated by honing.
- Bearings are available in standard size and several under-sizes.
