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 hydraulic system responsiveness or a slight increase in operating temperature. If ignored, the pump's output will continue to degrade, leading to sluggish or unpredictable machine movements. Continued operation with a failing pump can lead to overheating and potential damage to other hydraulic components.

Installation Tip

Thoroughly flush the hydraulic system to remove any contaminants before installing the new pump. Avoid overtightening hydraulic fittings, as this can damage the threads or the pump's ports.

Service Note

Inspect the hydraulic fluid and filter for signs of wear debris, and check hydraulic hoses for leaks or damage.
