Bearings
Inspect- Bearings for smooth rotation after oiling them.
- Bearing rollers for wear.
- Bearing cups for wear, cracks, brinelling and scoring.
- When replacing worn or cracked bearings and cups, make sure to replace bearings in sets.
- Low mileage bearings may have very small scratches and pits on the rollers and the bearing cups from the initial preload. Do not replace a bearing for this reason.
