Complete Track Adjuster Recoil Assembly (fits JCB) - AM JLA0329
High-quality complete track adjuster recoil assembly by AM (Aftermarket) for JCB JS and JZ Series tracked excavators. The track adjuster recoil unit serves two critical functions: maintaining correct track tension to prevent the track from de-railing, and absorbing shocks and overloads transmitted through the track to the idler wheel and undercarriage when working on hard or rocky ground. The complete set includes the hydraulic adjuster cylinder, recoil spring and idler yoke. AM Aftermarket grade — full interchangeability with the OEM part, precise fit without modification.

⚠ Important — verify before ordering: Always verify the part number of the adjuster fitted to your machine before ordering — different machine variants may require a different adjuster version. If in doubt, please contact us with your machine serial number.
Workshop Technical Tip: The track adjuster directly affects the safety and service life of the entire undercarriage. A track that is too loose will de-rail during sharp turns or in mud — one that is over-tensioned will rapidly wear rollers, sprockets and track link bushings. Check track sag regularly to the service manual specification. Exercise extreme caution when replacing the recoil assembly — the recoil spring operates under enormous pre-load. Always follow the correct service procedure and use a hydraulic press for disassembly. Never release the adjuster by loosening the valve without first de-loading the spring — this can cause a serious accident.
