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

A failing hydraulic pump may initially cause a gradual decrease in the speed and power of hydraulic functions. If ignored, this can progress to intermittent loss of hydraulic pressure and control. The ultimate consequence is the inability to perform essential tasks, leading to significant operational disruption.

Installation Tip

Before installation, ensure the hydraulic reservoir is filled with the correct type and amount of fluid, and bleed air from the system after installation. Do not reuse old hydraulic fluid or filters, as contamination is a primary cause of pump failure.

Service Note

Inspect the hydraulic fluid and filter, and check all hydraulic lines and connections for leaks during the replacement of this pump.
