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 noticeable slowdown in hydraulic system response and reduced power. If ignored, this can progress to inconsistent operation and potential overheating of the hydraulic fluid. Continued use with a faulty pump can lead to increased wear on other hydraulic system components.

Installation Tip

Prime the new pump by filling its inlet port with clean hydraulic fluid before connecting it to the system to prevent air entrapment. Ensure all mounting bolts are tightened evenly to avoid stressing the pump housing.

Service Note

When replacing the hydraulic pump, it is recommended to inspect and replace hydraulic filters and check the hydraulic fluid for signs of contamination.
