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 sign of a failing piston pump is often a sluggish or inconsistent response from hydraulic functions. If ignored, the system may lose significant power, leading to reduced productivity and potential overheating of the hydraulic fluid. Continued operation risks complete loss of hydraulic function, rendering the equipment inoperable.

Installation Tip

Ensure the hydraulic reservoir is filled with the correct type and amount of fluid before starting the pump. Never run the pump dry, as this can cause immediate internal damage.

Service Note

Inspect and replace the hydraulic filter and check the hydraulic fluid level and condition during pump replacement.
