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 piston pump include a noticeable decrease in hydraulic system performance, such as slower boom or bucket movements. If ignored, the pump's efficiency will continue to degrade, potentially leading to intermittent loss of hydraulic pressure and inability to operate implements. The primary risk is the inability to perform essential work functions and potential damage to other hydraulic components due to debris.

Installation Tip

Thoroughly clean the hydraulic system and ensure all fluid lines are free of contaminants before connecting the new pump. Avoid rotating the pump shaft by hand before it is properly seated and connected to the drive system.

Service Note

Replace the hydraulic filter and inspect hydraulic fluid for contamination when installing a new piston pump.
