Role of Part 3935619 Oil Filler Tube in Engine Systems

The 3935619 Oil Filler Tube is an essential component in the lubrication system of an engine, facilitating the proper arrangement and function of several key components.

Integration with the Oil Fill System

The Oil Filler Tube, designated as part 3935619, is directly connected to the oil fill system. Its primary function is to provide a conduit for oil to be introduced into the engine. This tube is typically threaded into the engine cover, ensuring a secure fit that prevents oil leaks during operation. The design of the tube often includes a gasket or O-ring to enhance the seal, maintaining the integrity of the oil fill process.

Connection to the Engine Cover

The engine cover, which encases the top of the cylinder block, is another component that interacts closely with the Oil Filler Tube. The tube is usually mounted on the cover, allowing for easy access during oil changes. The cover itself is designed to protect the internal components of the engine while providing necessary access points for maintenance, such as the oil filler cap that sits atop the tube.

Relationship with the Cylinder Block

Ultimately, the Oil Filler Tube plays a supporting role in the lubrication of the cylinder block. Once oil is introduced through the tube, it flows into the crankcase, where it is distributed throughout the engine. The cylinder block houses the cylinders, pistons, and other moving parts that require consistent lubrication to operate efficiently and endure prolonged use. The Oil Filler Tube ensures that the lubrication system remains topped up, allowing the engine to maintain optimal performance and longevity ³.

Conclusion

The Cummins 3935619 Oil Filler Tube is a vital component in the engine’s lubrication system, ensuring that the engine remains properly lubricated for optimal performance and longevity. Its robust design, compatibility with various engine models, and ease of maintenance make it a reliable choice for commercial truck applications.
