Role of Part 4015803 Lubricating Oil Supply Tube in Engine Systems

The lubricating oil supply tube, identified by part number 4015803, is an essential component in the lubrication system of an engine. Its primary function is to deliver lubricating oil from the oil pan to various engine components that require lubrication.

In the engine design, the lubricating oil supply tube is strategically positioned to ensure a consistent and reliable flow of oil. It connects to the oil pan, where the oil is stored, and extends to critical engine parts such as the crankshaft, camshaft, and valve train. This ensures that these components receive a steady supply of oil, which is vital for reducing friction and wear ⁴.

An alternative application of the lubricating oil supply tube is in systems where the oil is circulated through a lubricating oil suction mechanism. In such designs, the tube plays a role in drawing oil from the pan and directing it to the suction pump, which then distributes the oil throughout the engine.

Overall, the lubricating oil supply tube is a fundamental part of the engine’s lubrication system, ensuring that all moving components are adequately lubricated to operate efficiently and prolong the engine’s lifespan.

Conclusion

The 4015803 Lubricating Oil Supply Tube by Cummins is a critical component in the lubrication system of heavy-duty truck engines. Its role in delivering lubricating oil to critical engine components ensures reduced friction, wear, and enhanced engine performance and longevity.
