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 gear pump include a noticeable decrease in oil pressure, often indicated by a dashboard warning light. If ignored, the engine may begin to exhibit increased mechanical noise due to insufficient lubrication. Continued operation without addressing the issue risks severe internal engine damage from excessive friction and heat.

Installation Tip

Before installing the new pump, ensure the oil pickup tube and screen are thoroughly cleaned to prevent any debris from entering the new component. Avoid overtightening the mounting bolts, as this can distort the pump housing and lead to premature failure.

Service Note

When replacing the gear pump, it is highly recommended to also inspect and clean the oil pickup screen and replace the engine oil and filter.
