Cummins®

The Cummins 3938060 Dipstick is a specialized component designed for use in commercial trucks equipped with Cummins engines. Its purpose is to facilitate the monitoring of engine oil levels and condition, which is vital for maintaining the engine’s performance and longevity. This part is integral to routine maintenance practices and ensures that the engine operates within optimal parameters.

Basic Concepts of a Dipstick

A dipstick is a simple yet essential tool used in internal combustion engines to measure the level and condition of engine oil. It consists of a long, slender rod with a handle at one end, typically made from metal or high-strength plastic. The rod is inserted into the engine’s oil sump through a tube, and when withdrawn, the oil level can be read from markings on the rod. Additionally, the oil’s condition can be assessed by observing its color and consistency on the dipstick ¹.

Purpose of the Cummins 3938060 Dipstick

The Cummins 3938060 Dipstick plays a role in the operation of a truck by providing a means to monitor engine oil levels and condition. Proper oil levels are necessary for lubricating engine components, reducing friction, and dissipating heat. This part allows for regular checks to ensure that the oil level remains within the manufacturer’s specified range. It also enables the operator to check the oil’s condition, which can indicate the need for an oil change or further investigation into engine health ².

Installation and Usage

To install and use the Cummins 3938060 Dipstick, follow these steps:

1. Ensure the engine is turned off and has had sufficient time to cool down.
2. Locate the dipstick tube, typically found on the side of the engine block.
3. Remove the dipstick by pulling it straight out of the tube.
4. Wipe the dipstick clean with a lint-free cloth.
5. Reinsert the dipstick fully into the tube and then remove it again to check the oil level.
6. Observe the oil level against the markings on the dipstick and assess the oil’s condition.
7. If the oil level is low, add the recommended type and amount of oil.
8. Replace the dipstick securely in the tube to prevent oil leaks.

Maintenance and Care

To ensure the longevity and reliable performance of the Cummins 3938060 Dipstick, regular maintenance is recommended. Clean the dipstick after each use with a lint-free cloth to remove any oil residue. Inspect the dipstick for signs of wear or damage, such as bent or corroded sections, and replace it if necessary. Proper storage in a clean, dry place will also help maintain its condition.

Troubleshooting Common Issues

Common issues with the Cummins 3938060 Dipstick may include inaccurate oil level readings or physical damage to the dipstick. Inaccurate readings can often be resolved by ensuring the dipstick is fully seated in the tube and by cleaning it thoroughly before each use. Physical damage, such as bends or cracks, may require replacement of the dipstick to ensure accurate readings and prevent potential oil leaks.

Compatibility with Cummins Engines

• 6C8.3: The Dipstick part 3938060 is compatible with the 6C8.3 engine. This engine is known for its reliability and performance, often used in various industrial applications. The dipstick ensures that the oil level is within the optimal range, preventing engine damage due to low oil.

• QSL9 CM850 (CM2850): The Dipstick part 3938060 also fits the QSL9 CM850 (CM2850) engine. This engine is part of the Cummins QSL series, which is designed for heavy-duty applications. The dipstick is essential for maintaining the oil level in this high-performance engine, ensuring longevity and efficiency.

Role of Part 3938060 Dipstick in Engine Systems

The part 3938060 dipstick is an essential component in the engine system, facilitating the accurate measurement and monitoring of the oil level within the engine.

When the dipstick is inserted into the engine’s oil filler tube, it provides a direct interface for the mechanic or engineer to assess the oil level. This is achieved by withdrawing the dipstick and observing the oil mark against the graduated scale printed on the dipstick.

In conjunction with the oil level gauge, the dipstick ensures that the engine maintains optimal lubrication. The gauge, often integrated into the vehicle’s dashboard, relies on the information obtained from the dipstick to display the current oil level to the driver.

Regular checks using the dipstick help in identifying any anomalies in oil consumption, potential leaks, or the need for an oil change. This proactive monitoring is key to maintaining engine health and performance.

Furthermore, the dipstick’s design allows for easy removal and reinsertion, ensuring that the oil level can be checked quickly during routine maintenance or before starting the engine. This simple yet effective tool plays a significant role in the overall maintenance and operational efficiency of the engine system.

Conclusion

The Cummins 3938060 Dipstick is a vital component for maintaining the health and performance of Cummins engines. By providing accurate and reliable oil level readings, this part ensures that engines operate within optimal parameters, reducing the risk of damage and extending engine life. Regular use and maintenance of the dipstick are essential practices for any vehicle equipped with a Cummins engine.
