Komatsu Excavator Final Drive Motors & Travel Motors

Komatsu excavators range from compact machines to much larger construction equipment, making the exact model and available part-number information important for drive identification. Use the Komatsu selector above to reach the final drive listed for your machine. If you are starting with an old motor tag or a number that does not match the current listing, our team can help cross-reference the application.

Komatsu owners commonly need help with part-number lookup, weak or slow travel, and gear-oil or hydraulic-fluid leakage. Those details can help narrow the correct replacement and give useful context when diagnosing the machine. We supply brand-new OEM-equivalent, highly durable replacement drives, provide fitment assistance before shipment, and support the unit with fast U.S. delivery and our Lifetime Limited Warranty.

Popular Komatsu final drive applications include PC35MR-2, PC35MR-3, PC40-7, PC50UU-1, and PC45R-8. The model selector above includes the full Komatsu listing.

Komatsu Part-Number Lookup & Travel Motor Diagnosis

A Komatsu excavator that travels slowly or feels weak on one side may have a drive issue, but hydraulic causes should be considered before replacing the motor. Check for visible leakage, compare track behavior in both directions and note whether the problem changes as the machine warms up.

If you already have a Komatsu part number, include it when contacting us. If you do not, the machine model and the identification from the old drive are usually the best starting points. Our team can help compare those details and narrow the correct replacement.
