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

Initial signs of a failing hydraulic pump cartridge include a noticeable decrease in system pressure and slower response times for hydraulic functions. If left unaddressed, the pump may begin to cavitate or overheat, leading to intermittent loss of hydraulic power. Continued operation with a degraded cartridge risks damage to other critical hydraulic components.

Installation Tip

Ensure the hydraulic system is properly flushed and clean before installing the new cartridge to prevent immediate contamination. Avoid overtightening the cartridge retaining bolts, as this can distort the housing and cause leaks.

Service Note

When replacing a hydraulic pump cartridge, it is recommended to inspect and replace the hydraulic filter and check the hydraulic fluid level and condition.
