Sumitomo excavators include older machines that often remain in service long after the original final drive has accumulated substantial wear. Use the Sumitomo model selector below to see the OEM-equivalent, highly durable replacement drives currently listed. If the existing unit has a tag or part number that does not match the model cleanly, our team can help compare the application.
Common Sumitomo final-drive concerns include weak or slow travel, hydraulic-fluid leakage and the difficulty of rebuilding an older drive. These symptoms can help determine whether the drive needs further diagnosis or whether a complete replacement is the more practical option. We offer complete brand-new OEM-equivalent, highly durable replacement units with fitment assistance, fast U.S. shipping and Lifetime Limited Warranty coverage.
Popular Sumitomo final drive applications include S160 and SH40JX. The model selector above includes the full Sumitomo listing.
A Sumitomo travel drive that becomes weak under load should be evaluated alongside the machine's hydraulic system. Compare both travel sides and inspect the motor and gearbox for leakage or abnormal noise before deciding the final drive alone is at fault.
If the old assembly has extensive internal wear, a complete new unit can be more predictable than a partial rebuild. Save the motor tag and machine information and contact us if you need help confirming the replacement.
