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 gradual decrease in engine oil pressure is often the first sign of a failing piston pump. If left unaddressed, this can lead to increased engine noise and potential overheating. Continued operation with a compromised pump risks severe internal engine damage due to inadequate lubrication.

Installation Tip

Thoroughly clean the oil pan and pickup tube screen before installing the new pump to prevent immediate contamination. Ensure the pump shaft engages correctly with the drive mechanism without forcing it.

Service Note

Inspect the engine oil filter and oil cooler for any signs of blockage or debris when replacing the piston pump.
