Role of Part 3959100 Lubricating Oil Suction Tube in Engine Systems

The Part 3959100 Lubricating Oil Suction Tube is an integral component in the lubrication system of an engine, facilitating the efficient circulation of oil to various engine parts. This tube is responsible for drawing oil from the oil pan and transporting it to the oil pump.

In the lubrication system, the oil pan serves as the reservoir for the engine oil. As the engine operates, the lubricating oil suction tube extends into the oil pan to draw oil. This oil is then pumped through the oil pump, which pressurizes it before distribution to critical engine components such as the crankshaft, camshaft, pistons, and bearings.

The efficient functioning of the lubricating oil suction tube ensures a consistent supply of oil, which is essential for maintaining proper lubrication. This, in turn, reduces friction and wear on moving parts, contributing to the overall longevity and performance of the engine ³.

Conclusion

The Lubricating Oil Suction Tube (Part 3959100) is a critical component in the engine lubrication system, ensuring efficient oil circulation and maintaining engine health. Its robust design, compatibility with various Cummins engines, and the benefits it provides in terms of engine longevity and performance make it a valuable part for any Cummins engine system.
