Cummins Engine Oil Gauge Tube (Part 4942671)

The Cummins Oil Gauge Tube, part number 4942671, is a component in the oil monitoring system of certain Cummins engines. This part is designed to provide accurate readings of the engine’s oil pressure, ensuring that the engine operates within safe parameters.

Application in Cummins Engines

QSB4.5 Series Engines

• QSB4.5 CM2250 EC
• QSB4.5 CM850 (CM2850)

The Oil Gauge Tube is integral to the oil monitoring system in the QSB4.5 series engines, including the CM2250 EC and CM850 (CM2850) variants. These engines are known for their robust performance and reliability, often used in various applications such as agricultural machinery, generators, and industrial equipment.

In these engines, the Oil Gauge Tube connects to the oil pressure sensor, which measures the oil pressure and sends a signal to the engine’s control unit. This ensures that the engine’s oil pressure is continuously monitored, providing real-time data to the operator.

The installation of the Oil Gauge Tube is straightforward, requiring precise alignment to ensure accurate readings. It is typically mounted on the engine block, with the sensor end connected to the oil pressure sensor and the gauge end connected to the oil gauge on the dashboard.

Regular maintenance and inspection of the Oil Gauge Tube are essential to ensure it functions correctly. Any signs of wear, damage, or leaks should be addressed promptly to prevent potential engine damage due to inadequate oil pressure monitoring.

Role of Part 4942671 Oil Gauge Tube in Engine Systems

The 4942671 is an essential component in the accurate measurement and monitoring of oil levels within an engine system. This tube is integral to the functionality of the oil level gauge, which is a vital instrument for maintaining the health and performance of the engine.

Integration with the Oil Level Gauge

The Oil Gauge Tube is directly connected to the oil level gauge, facilitating the precise measurement of the oil level within the engine. The gauge relies on the tube to draw oil from the sump or oil pan, allowing the gauge to display the current oil level. This information is essential for ensuring that the engine is adequately lubricated, which is fundamental to its operation and longevity.

Ensuring Accurate Oil Level Readings

Accurate oil level readings are paramount for the proper functioning of the engine. The Oil Gauge Tube ensures that the oil level gauge provides consistent and reliable data. This is achieved through the tube’s design, which allows for the smooth and uninterrupted flow of oil to the gauge. Without this component, the gauge would be unable to provide accurate readings, potentially leading to engine damage due to insufficient lubrication.

Maintenance and Monitoring

Regular monitoring of the oil level is a key aspect of engine maintenance. The Oil Gauge Tube plays a significant role in this process by enabling the oil level gauge to function correctly. Engineers and mechanics must ensure that the tube is free from obstructions and damage, as any issues with the tube can affect the accuracy of the oil level readings. This, in turn, can impact the overall performance and reliability of the engine.

Supporting Engine Health

By ensuring that the oil level gauge operates accurately, the Oil Gauge Tube indirectly supports the health of the engine. Proper lubrication is essential for reducing friction and wear on engine components. The Oil Gauge Tube, therefore, contributes to the engine’s efficiency and durability by helping to maintain optimal oil levels.

Conclusion

In summary, the 4942671 Oil Gauge Tube is a fundamental component in the engine system, working in conjunction with the oil level gauge to provide accurate and reliable oil level readings. This ensures that the engine remains well-lubricated, supporting its performance and longevity.
