Exact-Fit Replacement for the Kubota KX121-3SS Travel Motor

Replace the final drive on your Kubota KX121-3SS mini excavator with this component, which is built to OEM specifications. The OEM part number is RD138-61292 or RD138-61293. For added confirmation of fit, reach out to share your model and serial number with us. Our Precision Pros can verify that this component is right for you.

This part matches OEM performance for flow, pressure and torque. It also bolts directly to the factory frame and matches the original hose port locations and gear ratio. The drives have two case drain ports, similar to OEM parts, allowing for installation on either side of the machine. We sell a new and complete final drive motor assembly that's field-tested and ready to install. 

Why Precision Final Drives?

With us, you gain a limited lifetime warranty, promising freedom from defects in materials and work under regular use for up to two years. Our parts typically arrive within two to five business days at any location in the continental U.S. If you need to return the part, you can do so within 30 days of receipt, provided the motor is new and unused. 

We get our motors from the same factories that supply OEM motors to major brand machines. This approach provides a component with proven reliability at an aftermarket price that is often significantly lower.
