When Should the Bearing Be Replaced?
Inspection or replacement may be necessary if you notice:
- Abnormal knocking or grinding noise
- Increased engine vibration
- Excessive crankshaft movement or play
- Rough crankshaft rotation
- Bearing corrosion
- Pitting or wear on the bearing surface
- Damage found during engine overhaul
- Crankshaft repair or replacement
When rebuilding an engine, it is recommended to inspect the crankshaft, bearings, oil seals, connecting rods and related components together.
Installation Recommendations
- Disassemble the crankshaft assembly according to the correct service procedure.
- Inspect the crankshaft and bearing installation area for wear or damage.
- Keep all mating surfaces clean before installation.
- Do not install a bearing that has been dropped or damaged.
- Use suitable professional tools when pressing or installing the bearing.
- Avoid applying excessive force directly to the bearing rolling elements.
- Check crankshaft rotation after assembly.
- Replace related oil seals or worn components when necessary.
Professional engine installation is recommended.
