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 sign of failure is often a noticeable reduction in track speed or erratic movement of one track. If ignored, the gearbox may begin to make loud grinding noises, and the affected track could lose all power. The worst consequence is the inability to move the excavator, potentially stranding it on site.

Installation Tip

Before installing, ensure the mounting surfaces on the excavator frame are clean and free of old sealant or debris. Properly align the gearbox to avoid stressing the mounting bolts during installation.

Service Note

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