PC55MR-5 Track Adjuster Kit Description
YNF16434 is a complete seal kit for the track adjuster (recoil cylinder) of Komatsu PC55MR-5 mini excavators. Track adjusters maintain proper track tension by using a grease-filled hydraulic cylinder system, and seal failure can lead to loss of tension, track derailment, or damage. This kit contains high-quality seals—dust wipers, piston seals, O-rings, and support rings—manufactured from PU, PTFE, and NBR to ensure long-lasting performance in tight, high-pressure environments. Suitable for compact construction machines, this kit is trusted by repair shops and part resellers globally.
