161-4110 Oil Pump — Cat 3408

This oil pump is a critical component of the engine's lubrication system, responsible for circulating engine oil to reduce friction and dissipate heat. It is manufactured to meet stringent OEM quality standards, ensuring superior performance compared to a worn pump that may exhibit reduced flow or internal leakage. Operators may notice a drop in oil pressure, increased engine noise, or the illumination of the oil pressure warning light when this pump begins to fail.

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 oil pump may initially present as intermittent low oil pressure readings, especially at idle or under load. If left unaddressed, this can lead to increased engine noise, overheating, and accelerated wear on critical internal components. Continued operation with a compromised lubrication system risks severe engine damage.

Installation Tip

Ensure the oil pickup tube and screen are thoroughly cleaned and free of any debris before installation. Avoid overtightening the mounting bolts, as this can distort the pump housing and cause premature failure.

Service Note

Always inspect the oil pickup screen and oil pan for sludge or debris when replacing the oil pump.
