Failure Symptoms

The first signs of a failing travel gearbox often include unusual grinding or whining noises emanating from the drive area, or a noticeable reduction in track speed and power. If ignored, the gearbox may develop internal damage, leading to jerky or inconsistent movement, and potentially a complete loss of drive to one or both tracks. Continued operation risks severe damage to the gears, bearings, and final drive components, resulting in costly repairs and significant downtime.

Installation Tip

Ensure the drive motor and gearbox mounting surfaces are perfectly clean and free of old sealant or debris before assembly. Carefully align the gearbox input shaft with the drive motor output, ensuring it engages smoothly without forcing.

Service Note

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