Cummins Oil Gauge Tube (Part 3948613) Compatibility

The Cummins Oil Gauge Tube, identified by part number 3948613, is a component in the engine’s lubrication system. This part is designed to provide accurate readings of the oil pressure, ensuring the engine operates within safe parameters. Below is a detailed description of how this part fits within various Cummins engines, grouped by their series and applications.

ISC CM554 Series

The ISC CM554 engine is a part of the Cummins ISC series, known for its robust performance and reliability in heavy-duty applications. The Oil Gauge Tube (3948613) in this engine series is installed to monitor the oil pressure directly from the oil system. It connects to the oil pressure sensor, which then sends the data to the engine control unit (ECU). This ensures that the driver is immediately informed of any fluctuations in oil pressure, which could indicate potential engine issues ².

QSK Series

In the QSK series, the Oil Gauge Tube (3948613) plays a similar role. This series is designed for high-performance applications, often found in marine and industrial settings. The installation process involves threading the tube into the oil pressure port on the engine block. The tube must be securely fitted to prevent leaks and ensure accurate readings. The connection point is typically located near the oil filter or oil pressure sensor, ensuring that the gauge can effectively monitor the oil pressure ².

L10 Series

The L10 engine series, another robust Cummins offering, also utilizes the Oil Gauge Tube (3948613). This part is essential for maintaining the integrity of the engine’s lubrication system. The installation involves connecting the tube to the oil pressure sensor, which is usually mounted on the engine block. The tube’s design allows for a precise measurement of oil pressure, which is crucial for the engine’s longevity and performance ².

K Series

In the K series engines, the Oil Gauge Tube (3948613) is integral to the engine’s diagnostic and monitoring systems. This series is widely used in various applications, including agricultural and construction equipment.

Role of Part 3948613 Oil Gauge Tube in Engine Systems

The 3948613 Oil Gauge Tube is a component in the accurate measurement and monitoring of oil levels within an engine system. It works in conjunction with the oil level sensor to provide precise readings that are displayed on the gauge.

When the engine is operational, oil is circulated through various components to ensure lubrication and cooling. The oil gauge tube facilitates the passage of oil to the oil level sensor, which detects the height of the oil within the sump. This sensor then sends a signal to the gauge, allowing the driver or operator to monitor the oil level in real-time.

Maintaining the correct oil level is important for the longevity and performance of the engine. If the oil level is too low, it can lead to insufficient lubrication, increased friction, and potential engine damage. Conversely, if the oil level is too high, it can cause foaming, which reduces the oil’s effectiveness and can lead to engine issues.

The oil gauge tube ensures that the oil level sensor receives an accurate representation of the oil level, enabling the gauge to provide reliable readings. This, in turn, allows for timely maintenance and oil top-ups, contributing to the overall efficiency and reliability of the engine system ².

Conclusion

The Cummins 3948613 Oil Gauge Tube is a critical component for maintaining the efficiency and reliability of Cummins engines.
