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 signs of a failing separator plate might include a subtle increase in hydraulic motor noise or a slight reduction in torque output. If left unaddressed, the compromised sealing and alignment can lead to significant power loss and internal leakage within the motor. Continued operation risks accelerated wear on other motor components and potential hydraulic system failure.

Installation Tip

Ensure all mating surfaces are perfectly clean and free of any debris or old gasket material before assembly. Avoid applying excessive force when seating the plate, as it should fit precisely.

Service Note

Inspect the hydraulic motor's pistons, cylinder block, and shaft seal for wear or damage when replacing the separator plate.
