Failure Symptoms

Early signs of a failing piston motor group might include a gradual reduction in travel speed or a noticeable decrease in tractive effort. If the issue is not addressed, the motor can begin to leak hydraulic fluid or lose its ability to provide consistent power, potentially leading to immobilization of the machine. This can result in significant operational delays and the need for extensive repairs.

Installation Tip

Before installation, ensure all hydraulic lines connected to the motor are clean and free of debris to prevent contamination. Avoid overtightening mounting bolts, as this can warp the motor housing and lead to leaks or premature failure.

Service Note

Inspect the hydraulic pump, final drive, and hydraulic fluid for signs of wear or contamination when replacing the piston motor group.
