161-4113 Oil Pump — Cat C15 C16

This is a high-quality oil pump, integral to the engine's lubrication system, responsible for circulating oil to reduce friction and dissipate heat. Manufactured to meet rigorous OEM specifications, it ensures consistent oil pressure and flow, unlike worn pumps that can lead to insufficient lubrication and increased engine wear. Operators may notice symptoms such as a drop in oil pressure warning light illumination, increased engine noise, or overheating if this oil pump is failing.

Failure Symptoms

The first sign of a failing oil pump is often a fluctuating or low oil pressure reading on the instrument panel. If ignored, this can lead to inadequate lubrication of engine bearings and other moving parts, causing increased friction and heat. Prolonged operation without proper lubrication can result in severe engine damage, including seized bearings or damaged crankshafts.

Installation Tip

Ensure the oil pickup tube and screen are clean and properly seated in the oil pan before installing the new pump. Do not reuse old gaskets or seals; always use new ones to prevent leaks.

Service Note

Replace the engine oil and oil filter simultaneously with the oil pump.
