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 indicators of a failing hydraulic piston pump include a noticeable decrease in the speed and power of hydraulic functions. If ignored, the system may become increasingly sluggish, and the pump may start to produce whining or groaning noises. Continued operation risks overheating the hydraulic fluid and potential damage to other system components.

Installation Tip

Thoroughly flush the hydraulic system and replace the hydraulic filter before installing the new pump to prevent contamination. Ensure the pump shaft is properly aligned with the drive coupling to avoid premature wear.

Service Note

When replacing the hydraulic pump, always change the hydraulic filter and inspect the hydraulic fluid for contamination.
