Role of Part 3920179 Oil Suction Connection in Engine Systems

The part 3920179 Oil Suction Connection is an essential component in the lubrication system of an engine. It is specifically designed to interface with the oil pan and facilitate the efficient suction of oil.

Interaction with the Oil Pan

The Oil Suction Connection is mounted on the oil pan, which serves as the reservoir for the engine’s lubricant. The connection point allows for a secure and leak-proof attachment, ensuring that the oil can be drawn from the pan without any loss. This is important for maintaining the proper oil level and pressure within the engine ⁸.

Oil Suction Process

Once connected, the Oil Suction Connection works in tandem with the oil pump. The pump creates a vacuum that pulls oil through the connection and into the engine’s lubrication circuits. This process ensures that all moving parts within the engine receive a consistent supply of oil, which is vital for reducing friction and wear ⁹.

Maintenance and Efficiency

Regular inspection and maintenance of the Oil Suction Connection are important to ensure its efficiency. Any blockages or leaks at this connection point can lead to inadequate oil supply, potentially causing increased wear on engine components and reduced overall performance.

Conclusion

In summary, the Oil Suction Connection 3920179 plays a significant role in the engine’s lubrication system by providing a reliable interface between the oil pan and the oil pump, ensuring that the engine receives a steady supply of oil for optimal operation ¹⁰.
