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 hydraulic pump is often a noticeable reduction in the speed and power of hydraulic-driven functions. If the issue progresses, the pump may start to make unusual noises, and the hydraulic oil temperature can rise significantly due to internal leakage. Continued operation risks complete loss of hydraulic power, rendering the equipment inoperable and potentially causing damage to other hydraulic components.

Installation Tip

Ensure the pump shaft and mounting surfaces are clean and free of any debris before installation to prevent seal damage. Do not use excessive force when aligning the pump to the drive, as this can damage the shaft or coupling.

Service Note

When replacing a hydraulic pump, it is crucial to inspect and replace the hydraulic filter, and check the hydraulic fluid for signs of contamination.
