Role of Part 3035028 Sending Unit in Engine Systems

The Part 3035028 Sending Unit is an integral component in various engine systems, particularly those involving oil management and cooling. It works in conjunction with several key components to ensure optimal engine performance and longevity.

Integration with Oil Coolers and Lubricating Systems

1. Engine Oil Cooler and Lubricating Oil Cooler: The Sending Unit monitors the temperature of the engine oil as it passes through the cooler. This data is vital for maintaining the oil within its optimal temperature range, ensuring efficient lubrication and cooling.

2. Full Flow Oil Filter and Lubricating Oil Filter: In systems where a full flow oil filter or a lubricating oil filter is employed, the Sending Unit provides real-time data on oil pressure and temperature. This information helps in assessing the filter’s condition and efficiency, allowing for timely maintenance or replacement.

3. Filter/Cooler Lub Oil and Lub Oil Filter Cooler: When integrated with a filter/cooler lub oil setup, the Sending Unit plays a dual role. It not only monitors the oil’s temperature but also its pressure, providing comprehensive data for the management of both filtration and cooling processes.

Pressure Sensing and Switch Functionality

The Sending Unit often incorporates a pressure sensing switch. This switch is designed to activate or deactivate certain engine functions based on the oil pressure readings. For instance, if the oil pressure drops below a certain threshold, the switch can trigger a warning signal or even shut down the engine to prevent damage.

Assembly and Conversion Kits

In more complex setups, such as a lubricating oil cooler (top-level assembly) or a lubricating oil cooler conversion kit, the Sending Unit offers detailed insights into the system’s performance. It helps in fine-tuning the assembly or conversion process, ensuring that all components work in harmony.

Comprehensive Monitoring in Filter & Cooler Assy

When part of a filter & cooler assembly, the Sending Unit offers a holistic view of the system’s health. It monitors both the filtration efficiency and the cooling effectiveness, providing a comprehensive dataset for system diagnostics and maintenance planning.

Conclusion

In summary, the Cummins 3035028 Sending Unit is a versatile component that enhances the functionality of various engine systems by providing real-time data on oil pressure and temperature.
