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 cartridge is often a sluggish response in hydraulic functions or a noticeable drop in system pressure. If ignored, internal leaks within the cartridge will worsen, leading to significantly reduced performance and potential overheating of the hydraulic fluid. Continued operation risks complete hydraulic system failure, immobilizing the equipment.

Installation Tip

Thoroughly flush the hydraulic system and replace the hydraulic filter before installing the new cartridge to prevent contamination. Ensure all O-rings and seals are properly lubricated and seated to prevent leaks.

Service Note

Always replace the hydraulic fluid and filter when servicing the hydraulic pump cartridge.
