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

Initial signs of failure may include a noticeable decrease in the speed or power of hydraulic functions. If ignored, the motor's performance will continue to degrade, leading to intermittent operation and potential system overheating. Continued operation with a failing motor risks damage to other hydraulic components due to contamination or inconsistent pressure.

Installation Tip

Thoroughly flush the hydraulic system to remove any debris before installing the new motor. Avoid overtightening the mounting bolts, as this can distort the motor housing and cause internal binding.

Service Note

Inspect hydraulic fluid for contamination and check the hydraulic filter for debris during replacement.
