Caterpillar Excavator Final Drive Motors & Travel Motors

Caterpillar excavators cover a broad range of machine sizes and model generations, making accurate drive identification especially important. Use the CAT model selector above to reach the final drive listed for your machine, or contact us with the excavator model, existing part number and motor-tag information when the match is uncertain. Our team can help compare specifications rather than relying on appearance alone.

Common Caterpillar final-drive problems include worn main bearings, damaged gear teeth or gear bearings, upper or lower shaft wear, and oil or hydraulic-fluid leakage from aging seals. We supply brand-new OEM-equivalent, highly durable replacement drives for CAT applications and back them with fast U.S. shipping and our Lifetime Limited Warranty.

Popular Caterpillar final drive applications include 304CR, 303.5, 305CR (9 bolt sprocket), 303.5CCR, and 307C. The model selector above includes the full Caterpillar listing.

Caterpillar Final Drive Bearings, Gears, Shafts & Seals

Older or heavily used CAT final drives can develop several mechanical problems before complete failure. Main-bearing wear may show up as looseness or noise; damaged gear teeth or bearings can produce rough operation; shaft wear can affect alignment; and worn seals can allow gear oil or hydraulic fluid to escape. A machine that travels slowly or lacks power should also be checked for hydraulic causes before the final drive is blamed.

Routine service can delay avoidable damage. See our bearing-failure information and final drive maintenance guidance. If replacement is necessary, send us the CAT model and part-number information so we can help confirm the correct drive.
