Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first indication of a failing final drive gearbox is often a noticeable decrease in travel speed or power, accompanied by unusual noises like grinding or whining. If ignored, this can lead to complete loss of drive capability and potential damage to the drive motor or planetary gears. Continued operation risks immobilizing the equipment.

Installation Tip

Thoroughly clean the mounting surfaces and inspect the drive sprocket for wear before installing the new gearbox. Ensure the correct type and amount of hydraulic oil is used during filling to prevent internal damage.

Service Note

Inspect the hydraulic drive motor, planetary gears, and track chains for wear or damage when replacing the final drive travel gearbox.
