Component Usage

The Cummins part 3863702, a Mounting Spacer, is designed to fit a variety of Cummins engines, ensuring proper alignment and stability during operation. This part is integral to the mounting systems of several engine models.

For the B6.7 CM2670 B164C and L8.9 CM2670 L134C engines, the Mounting Spacer 3863702 plays a role in maintaining the structural integrity of the engine assembly. It ensures that the engine is securely fastened to its mounting points, reducing vibrations and enhancing operational efficiency.

In the case of the QSB4.5 CM850 (CM2850) and QSB6.7 CM2250 engines, the Mounting Spacer 3863702 is used to maintain precise alignment between the engine and its mounting brackets. This precision is vital for the smooth operation of these engines, particularly in applications where vibration control is critical.

For the QSB6.7 CM2350 B105 and QSB6.7 CM850 (CM2850) engines, the Mounting Spacer 3863702 helps to ensure that the engine remains securely attached to the vehicle or machinery. This part helps to distribute the engine’s weight evenly, preventing undue stress on any single mounting point.

Lastly, for the QSB7 CM2880 B117 engine, the Mounting Spacer 3863702 is used to maintain the engine’s position relative to the vehicle’s chassis. This ensures that the engine operates smoothly and efficiently, with minimal vibration and noise.

Gauge and Oil Level System

In the gauge and oil level system, the Mounting Spacer ensures that the oil level sensor is correctly positioned relative to the oil pan. This precise alignment allows for accurate oil level readings, which are vital for maintaining optimal engine lubrication and preventing potential damage from low oil levels.

Harness and Electronic Control Module (ECM) Wiring

When integrating the harness with the ECM wiring, the Mounting Spacer plays a key role in maintaining the correct distance between the wiring components. This ensures that there is no undue stress on the wires, reducing the risk of damage or failure. Proper spacing also aids in managing heat dissipation, which is crucial for the longevity and reliability of the electronic components.

Sensor Alignment

For sensors such as the oil level sensor, the Mounting Spacer ensures that the sensor is installed at the correct height within the oil pan. This accurate placement is necessary for the sensor to provide reliable data to the ECM, allowing for precise control of the engine’s oil management system.

Conclusion

The Cummins 3863702 Mounting Spacer is integral to the proper functioning of various engine components by ensuring accurate alignment, spacing, and stress management. Its role in facilitating the efficient operation of gauges, wiring harnesses, and sensors underscores its importance in engine system integration.
