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

Early indications of a failing hydraulic piston motor include a gradual loss of drive power and slower response times. If ignored, the motor may begin to make grinding noises and exhibit erratic movement, potentially leading to a complete loss of drive. Continued operation risks severe damage to the drive train and immobilization of the equipment.

Installation Tip

Ensure the hydraulic system is thoroughly flushed and clean before installing the new motor to prevent contamination. Avoid overtightening the mounting bolts, as this can distort the motor housing or damage the mounting surface.

Service Note

Inspect hydraulic lines, drive shafts, and final drive components for wear or damage when replacing the hydraulic piston motor.
