Hitachi 9303132 Track Adjuster Assembly

The 9303132 track adjuster assembly is a critical undercarriage component designed for Hitachi 20-25 metric ton class hydraulic excavators. It combines the hydraulic adjuster cylinder and the recoil spring into a single unit responsible for maintaining proper track tension and absorbing shock loads during operation. This assembly fits Hitachi models ZH200-A, ZH200LC-A, ZX200-5G, ZX200LC-5G, ZX210H-5G, ZX210K-5G, ZX210LCH-5G, ZX210LCK-5G, ZAXIS200LC-3, ZAXIS245USLC-5N, and ZAXIS245USLC-6N. It also cross-references to John Deere 245G, 245GLC, 245P excavators. The unit is manufactured to OEM dimensions using high-strength alloy steel for the cylinder body and spring steel for the recoil spring, ensuring durability in heavy construction and mining environments. Regular inspection and seal replacement are recommended to prevent hydraulic leakage and tension loss.
