When to replace track adjusters
- Track that will not hold tension after greasing
- Grease leaking at the cylinder seal or valve
- A broken or sagging recoil spring
- A bent or scored rod
What to confirm before ordering
- OEM number on the old assembly or in the parts book
- Complete assembly, cylinder only or spring only
- Overall length and spring dimensions

Safety: a recoil spring is under very high load. Have a trained technician remove and fit it.
