Main Function
The 161-4112 engine oil pump draws lubricating oil from the engine oil supply and circulates it through the lubrication system at the required pressure.
Reliable oil circulation is essential for protecting internal engine components during high-load and continuous-duty operation. A properly functioning oil pump helps support:
Stable Oil Pressure • Continuous Lubrication • Reduced Friction • Improved Component Protection • Reliable Engine Operation
A worn or damaged oil pump may contribute to symptoms such as:
- Low engine oil pressure
- Oil pressure warning
- Abnormal engine noise
- Insufficient lubrication
- Increased internal component wear
- Excessive engine temperature
- Unstable oil pressure at different engine speeds
- Premature bearing or engine component damage
If low oil pressure is detected, the complete lubrication system should be inspected before replacing the pump.
