Failure Symptoms

Early indicators of a failing piston motor group include sluggish movement, reduced tractive effort, or intermittent loss of power. If ignored, the motor can seize or leak excessively, leading to a complete loss of drive on one side of the machine. This can result in uncontrolled movement and potential damage to the final drive components.

Installation Tip

Thoroughly flush the hydraulic lines and clean the motor mounting area before installation to prevent contamination. Avoid using excessive force when aligning the motor shaft with the drive train, as this can damage the splines.

Service Note

Inspect the hydraulic pump and final drive gears for wear or damage when replacing the piston motor group.
