Track adjuster cylinder seal kit for CAT 315D L series excavators — restores proper track tension and stops grease loss from the recoil cylinder.

Replacement seal set for the grease-loaded track tensioner cylinder (also called "track adjuster" or "recoil cylinder"). Worn adjuster seals cause loose tracks, accelerated undercarriage wear, and grease contamination of the track frame.

Kit contents:
- Rod seal (NBR/PU)
- Wiper / dust seal
- O-rings and back-up rings
- Grease nipple seal

Materials: NBR and PU compounds rated for grease and outdoor service across the full Canadian temperature range.

Fits CAT 315D L track adjusters.
