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 pump failure include slow or erratic hydraulic operation and a noticeable drop in system pressure. If left unaddressed, the pump may begin to make loud whining or grinding noises, and hydraulic functions could cease entirely. This can lead to a complete loss of operational capability for the machine.

Installation Tip

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

Service Note

Inspect the hydraulic fluid for contamination and replace the hydraulic filter element when installing a new pump.
