Role of Part 3964069 Oil Suction Connection in Engine Systems

The part 3964069 Oil Suction Connection is an essential component in the lubrication system of an engine, facilitating the efficient circulation of oil. This component interfaces directly with the oil pan kit, which is a comprehensive assembly designed to contain and manage the engine oil. The oil pan, a primary element within the oil pan kit, serves as the reservoir for the engine oil.

The Oil Suction Connection is strategically positioned to draw oil from the oil pan. It connects to the oil pump, which is responsible for circulating the oil throughout the engine. This connection ensures a consistent and reliable flow of oil from the pan to the pump, which is vital for maintaining proper lubrication of engine components.

As oil is suctioned from the pan, it passes through the Oil Suction Connection and into the oil pump. The pump then pressurizes the oil and distributes it to various engine parts, including bearings, pistons, and other moving components. This continuous circulation helps to reduce friction, dissipate heat, and remove contaminants from the engine, contributing to its overall performance and longevity.

In summary, the part 3964069 Oil Suction Connection plays a significant role in the engine’s lubrication system by ensuring a steady supply of oil is available for the pump, thereby supporting the efficient operation and maintenance of the engine.

Conclusion

The 3964069 Oil Suction Connection by Cummins is a critical component in the engine lubrication system, ensuring the efficient circulation of oil and contributing to the overall performance and reliability of heavy-duty trucks. Its durable construction, secure fit, and reliable operation make it an essential part for maintaining optimal engine health. Regular maintenance and prompt troubleshooting of common issues are recommended to ensure the longevity and efficiency of this component.
