225-8329 Oil Pump — Cat 312D2 315C

This oil pump is essential for the engine's lubrication system, drawing oil from the sump and delivering it under pressure to all critical engine components. Manufactured to meet stringent OEM quality standards, it provides reliable oil flow and pressure, unlike a worn pump that may exhibit reduced output. Operators may observe a fluctuating or low oil pressure reading, increased engine noise, or the oil pressure warning light illuminating when this pump is failing.

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 drop in oil pressure, often indicated by the dashboard warning light or gauge, is the first sign of an oil pump issue. If ignored, this can lead to increased friction, overheating, and severe internal engine damage due to lack of lubrication.

Installation Tip

Ensure the oil pickup tube and screen are clean and properly sealed to prevent oil starvation. Prime the new oil pump with clean engine oil before installation to ensure immediate lubrication upon startup.

Service Note

Inspect the oil pickup screen and oil pan for sludge or debris, and check the engine's oil filter for signs of excessive wear or contamination.
