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 the first sign of a failing piston pump. If ignored, this can lead to increased friction and heat within the engine, potentially causing component wear. Continued operation without addressing the issue risks severe internal engine damage due to inadequate lubrication.

Installation Tip

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

Service Note

Inspect the engine oil pickup screen and oil pan for debris and sludge during replacement.
