20Y-30-12112 Spring Recoil Fits Komatsu Models

One New Aftermarket Replacement Spring Recoil for Komatsu Excavators

This recoil spring (also called an idler cushion spring or track adjuster spring) is a heavy-duty undercarriage component housed within the track adjuster and recoil group assembly. It acts as a shock absorber for the front idler, protecting the undercarriage from heavy impact and overload while maintaining proper track tension for reliable operation across rugged terrain. Part number 20Y-30-12112 is the current superseding number, replacing legacy OEM numbers 20Y-30-12110 and 20Y-30-12111.
