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 hydraulic pump cartridge is typically a noticeable decrease in the speed or power of hydraulic functions. If ignored, this can progress to erratic or jerky movements, and the pump may start to make loud whining or groaning noises. Severe failure can result in a complete loss of hydraulic pressure, rendering the equipment inoperable.

Installation Tip

Thoroughly flush the hydraulic system and clean the reservoir before installing the new cartridge to remove any metal particles or debris. Ensure all seals on the new cartridge are properly lubricated with clean hydraulic fluid before assembly.

Service Note

Inspect the hydraulic system's filter, fluid level, and reservoir for contamination when replacing the pump cartridge.
