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

A failing hydraulic pump may first manifest as a noticeable decrease in the speed or power of hydraulic functions. If operation continues, the system may become increasingly sluggish, with intermittent loss of hydraulic pressure. The ultimate risk is the inability to operate critical functions, leading to equipment downtime.

Installation Tip

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

Service Note

Inspect hydraulic fluid levels and condition, and check all hydraulic hoses and fittings for leaks or damage during pump replacement.
