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 hydraulic pump include a noticeable decrease in the speed and responsiveness of hydraulic functions. If ignored, the pump may begin to whine or cavitate, leading to intermittent loss of power and potential system overheating. The worst-case scenario is a complete loss of hydraulic power, rendering the machine inoperable.

Installation Tip

Thoroughly flush the hydraulic system to remove any contaminants before installing the new pump. Never run the pump dry; ensure it is fully primed with hydraulic fluid before initial startup.

Service Note

Inspect hydraulic filters, hoses, and cylinders for debris or signs of wear when replacing the hydraulic pump.
