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 include a gradual loss of hydraulic system power and slower implement speeds. If left unaddressed, the pump's performance will continue to degrade, leading to increased cycle times and potential overheating of the hydraulic fluid. Continued operation with a failing pump risks damage to other critical hydraulic components.

Installation Tip

Ensure the hydraulic reservoir is completely drained and flushed before installing a new pump to prevent contamination. Avoid overtightening the mounting bolts, as this can distort the pump housing and lead to premature failure.

Service Note

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