Main & Connecting Rod Bearings: Notes
- Inspect each bearing for peeling, melting, seizure or improper contact. Replace defective bearings. Measure outside diameter of crankshaft and connecting rod journals to determine if out-of-round or tapered.
- Use Plastigage method to measure bearing clearance. If clearance exceeds limits, bearing should be replaced or undersize bearing installed. Undersize bearings are available in.25 mm.50 mm, and.75 mm undersizes.
