When to replace track rollers
- Tread diameter worn down, or a flange worn thin or sharp
- Oil leaking from the seal at the end of the roller
- A roller that no longer turns and has a flat spot on the tread
- Play in the shaft when the roller is levered
What to confirm before ordering
- OEM number on the old roller or in the parts book
- Single-flange or double-flange: many machines use both
- Quantity per side: long-track (LC) machines often carry more rollers
- Machine model and serial number
