Role of Part 3930682 Oil Filler Tube in Engine Systems

The Part 3930682 Oil Filler Tube is an essential component in the lubrication system of an engine, facilitating the proper flow and distribution of oil to various engine components.

When integrated into the engine arrangement, the Oil Filler Tube serves as a conduit for oil to be introduced into the system. It is typically connected to the oil fill port, which is a designated opening on the engine cover. This cover, often made of metal or composite material, protects the internal components of the engine while providing access points for maintenance procedures.

The Oil Filler Tube is part of a comprehensive Oil Filler Tube Kit, which may include additional components such as gaskets and seals to ensure a secure and leak-free connection. Once the tube is properly installed, it allows oil to be poured into the engine, traveling through the tube and into the cylinder block.

The cylinder block is the structural core of the engine, housing the cylinders, pistons, and other critical components. Adequate lubrication is necessary to reduce friction, wear, and heat generation within these moving parts. The Oil Filler Tube ensures that the oil reaches the cylinder block efficiently, contributing to the overall performance and longevity of the engine ³.

Conclusion

The Cummins 3930682 Oil Filler Tube is a vital component in the maintenance and operation of heavy-duty truck engines. Its robust design, ease of installation, and compatibility with specific engine models make it an essential part for ensuring efficient oil management and engine lubrication. Regular maintenance and proper installation are key to maximizing the benefits of this Cummins part, contributing to the engine’s performance and longevity.
