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 piston pump may initially cause intermittent low oil pressure warnings or a slight increase in engine operating temperature. If left unaddressed, oil pressure will continue to drop, leading to increased friction and potential internal engine damage. Continued operation without adequate lubrication risks severe engine component wear and seizure.

Installation Tip

Ensure the oil pickup screen is thoroughly cleaned and free of any debris before installation to prevent immediate clogging of the new pump. Avoid overtightening the mounting bolts, as this can distort the pump housing and cause premature failure.

Service Note

Inspect the engine oil filter and oil pickup screen for any signs of wear or debris when replacing the piston pump.
