ZAX70 barely moving or only one track driving? A failed 9224123 travel motor assembly loses the hydraulic-to-mechanical conversion that propels the machine. Whether it is the motor section leaking internally or the gearbox losing reduction ratio, RITO supplies this complete travel motor assembly to restore full bilateral tractive effort on your ZAX70.

In Stock9224123 Travel Motor Assembly for Hitachi ZAX70 excavator. This complete unit integrates the hydraulic piston travel motor and the multi-stage planetary final drive gearbox. The motor converts high-pressure hydraulic flow into shaft torque; the gearbox multiplies that torque to drive the sprocket at working track speed. Replacing the complete assembly eliminates the installation risk of mixing worn and new components.

Hydraulic port size, port orientation and mounting flange bolt pattern confirmed for ZAX70 for direct swap without hose rerouting or adaptor flanges.
FAQ
Q: How do I diagnose whether the motor or gearbox section of the 9224123 assembly has failed?
A: Test motor case-drain flow: above OEM spec (typically 5-8 L/min) confirms motor internal wear. Gear noise or metal chips in gearbox oil with normal motor drain flow indicates gearbox failure. Both sections are included in the complete assembly replacement.
Q: Is it necessary to replace both travel motor assemblies at the same time?
A: Not required, but if total machine hours are high and one assembly has failed, inspecting the other side for comparable wear is worthwhile. Replacing both at the same time avoids a second major disassembly within a short period.
Q: What hydraulic oil should I use with the 9224123 travel motor?
A: Use the hydraulic oil grade specified in the ZAX70 operator manual (typically ISO VG 46 or 68 anti-wear hydraulic oil). Flush the travel circuit before connecting the new assembly to remove debris from the failed unit.
Q: How to confirm 9224123 fits my ZAX70?
A: Match hydraulic port sizes, motor case mounting bolt pattern and sprocket shaft dimensions. Provide the ZAX70 serial number to our team for confirmation.
Q: What quality options are available?
A: We provide original, OEM and high-quality aftermarket versions with stable supply capability.
