Doosan / Develon Excavator Final Drive Motors & Travel Motors

Doosan and Develon excavators range from compact machines to much larger equipment, and the correct travel motor depends on the exact model and configuration. Use the Doosan model selector above to find the final drive listed for your excavator. If the existing unit has a motor tag or part number that does not match the machine listing cleanly, our parts specialists can help compare the information.

Common Doosan final-drive symptoms include leaking gear oil or hydraulic fluid, a track drive that becomes weak or slow, and a motor that is nearly locked up. These symptoms can help determine whether the Doosan travel motor is approaching failure and whether complete replacement is appropriate. Brand-new OEM-equivalent, highly durable replacement units are supported by fast U.S. shipping and our Lifetime Limited Warranty.

Popular Doosan and Develon final drive applications include DX55, DH60-7, DX30Z, DX35Z, and DX85R-3. The model selector above includes the full Doosan and Develon listing.

Doosan Final Drive Symptoms: Leaks, Weak Travel & Lockup

A Doosan drive that slows down progressively can have a different problem from one that suddenly locks, so the symptom history matters. Look for gear-oil leakage at the gearbox, hydraulic-fluid leakage around the motor, abnormal noise, excess heat and whether the opposite travel side remains normal. Those observations can help separate a drive problem from a broader hydraulic issue.

If you are still diagnosing the machine, our final-drive troubleshooting guide provides a useful starting point. When replacement is appropriate, send us the Doosan model and identification numbers so we can help confirm the correct motor.
