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 a failing hydraulic pump include a noticeable decrease in hydraulic system pressure and flow. If left unaddressed, the pump's performance will continue to degrade, leading to significantly slower and weaker machine functions. This can impede productivity and potentially cause delays in critical operations.

Installation Tip

Thoroughly flush the hydraulic system to remove any contaminants before installing the new pump. Avoid overtightening the mounting bolts, as this can distort the pump housing.

Service Note

Inspect the hydraulic fluid and filter for debris, and check the hydraulic lines for any signs of internal damage or collapse.
