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 slight decrease in hydraulic system responsiveness. If left unaddressed, this can progress to intermittent loss of hydraulic power and increased operating temperatures. Continued operation with a compromised 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 hydraulic filters and check hydraulic fluid level and condition when servicing the hydraulic pump.
