NOK EX220-3 Travel Motor Seal Kit Assembly

This travel motor seal kit is designed for the final drive units on Hitachi EX220-3 and EX220LC-3 hydraulic excavators. It provides a complete set of seals required to rebuild the hydraulic travel motor, including piston seals, wear rings, O-rings, and backup rings manufactured to OEM dimensions. The kit corresponds to travel motor assembly part numbers 9119377, 9120000, 9131678, and 9132405. It is compatible with machines powered by the Hino H06C-T diesel engine. The seal components are constructed from high-grade NBR, HNBR, and PTFE compounds to withstand high operating pressures and temperature extremes encountered in excavator propulsion systems. This aftermarket replacement kit restores internal sealing integrity, preventing hydraulic fluid leakage and maintaining final drive efficiency.
