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

The first indication of a failing piston pump is typically a noticeable decrease in hydraulic system performance, such as slower boom or bucket movements. If left unaddressed, this can progress to complete loss of hydraulic function and inability to operate the equipment. Operating with a compromised hydraulic pump risks damage to other system components.

Installation Tip

Ensure the hydraulic reservoir is filled with the correct type and level of fluid before starting the pump. Avoid running the pump dry, as this can quickly cause internal damage.

Service Note

Inspect and replace the hydraulic filter and check the hydraulic fluid for contamination when replacing the piston pump.
