The design and specifications of the Oil Gauge Tube are tailored to fit the unique requirements of these engines, ensuring a secure and reliable connection. This compatibility is crucial for maintaining the integrity of the engine’s lubrication system, which is vital for its overall performance and longevity.

Role of Part 3935440 Oil Gauge Tube in Engine Systems

The part 3935440 Oil Gauge Tube is an integral component in the accurate measurement and monitoring of oil levels within an engine system. It interfaces directly with the oil level gauge, facilitating the transmission of oil level data from the engine’s oil reservoir to the gauge. This ensures that the oil level gauge provides a precise reading, allowing for timely maintenance and preventing potential engine damage due to low oil levels.

In the context of engine systems, the Oil Gauge Tube works in conjunction with the oil pump, which circulates oil throughout the engine to lubricate moving parts. The tube is positioned to draw oil from the sump or oil pan, where the oil collects after lubricating the engine components. As the oil level changes, the tube ensures that the gauge reflects these variations accurately.

Additionally, the Oil Gauge Tube is designed to withstand the high temperatures and pressures within the engine compartment, ensuring reliable performance over the engine’s operational life. Its integration with the oil level gauge system is essential for maintaining optimal engine health, as it allows engineers and mechanics to monitor oil levels continuously and make informed decisions regarding oil changes and system maintenance.

Conclusion

The Cummins 3935440 Oil Gauge Tube is a vital component in the maintenance and operation of heavy-duty truck engines. Its accurate monitoring of oil levels and pressure contributes significantly to engine efficiency, reliability, and longevity. Regular maintenance and prompt troubleshooting of common issues are essential to ensure the optimal performance of this Cummins part.
