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 symptoms of a failing piston pump include a noticeable slowdown in hydraulic functions and a decrease in lifting or digging power. If ignored, the pump may start to make whining or groaning noises, and hydraulic system responsiveness will continue to degrade. Continued operation risks complete loss of hydraulic power, rendering the equipment inoperable.

Installation Tip

Ensure the hydraulic fluid reservoir is clean and that no contaminants enter the system during the replacement process. Always prime the new pump with clean hydraulic fluid before connecting it to the system to prevent initial dry running.

Service Note

Flush the hydraulic system and replace the hydraulic filter element when installing a new piston pump.
