446-5395 Oil Pump — Cat 54B 68B

This is a high-performance oil pump responsible for circulating lubricating oil throughout the engine to reduce friction and dissipate heat. It is built to meet demanding OEM specifications, ensuring consistent oil pressure and flow, which is vital for engine longevity, unlike a worn pump that may deliver insufficient lubrication. Operators may notice a drop in oil pressure gauge readings, increased engine noise, or overheating when this oil 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

The first indication of a failing oil pump is often a reduction in oil pressure, indicated by the dashboard gauge. If ignored, this can lead to increased friction and heat within the engine, causing audible knocking or grinding noises. Prolonged operation with a faulty oil pump can result in severe internal engine damage and seizure.

Installation Tip

Ensure the oil pickup tube and screen are thoroughly cleaned and properly seated before installing the new pump to prevent immediate clogging. Do not reuse the old gasket; always install a new one.

Service Note

Clean or replace the oil suction strainer and inspect the engine oil pan for any debris when servicing the oil pump.
