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 travel gearbox is often a whining or grinding noise during operation, accompanied by a loss of drive power. If ignored, the gearbox can seize or lose significant torque, severely limiting or preventing machine movement. Continued operation risks damage to the final drive components and potential immobility of the equipment.

Installation Tip

Ensure the mounting surfaces are perfectly clean and that the drive shaft splines are properly lubricated before installation. Do not attempt to force the gearbox into position; it should align and slide into place smoothly.

Service Note

Inspect the hydraulic drive motor, planetary gears, and seals for wear or leaks when replacing the travel gearbox.
