Cummins Lubricating Oil Supply Tube Part 4010891 Compatibility

The Cummins Lubricating Oil Supply Tube part number 4010891 is designed to fit seamlessly within the engine systems of the QSV81G and QSV91G engines. This part is integral to the proper functioning of these engines, ensuring that the lubricating oil is efficiently distributed throughout the engine components.

QSV81G and QSV91G Engines

The QSV81G and QSV91G engines are part of Cummins’ robust lineup, known for their reliability and performance. The lubricating oil supply tube part 4010891 is engineered to meet the specific requirements of these engines, providing a critical function in maintaining engine health and longevity.

In these engines, the oil supply tube is responsible for channeling oil from the oil reservoir to various parts of the engine, ensuring that all moving components are adequately lubricated. This helps in reducing friction, preventing wear and tear, and maintaining optimal engine performance.

The design of the part ensures that it fits precisely within the engine’s architecture, allowing for smooth operation and easy installation. This compatibility is crucial for maintaining the engine’s efficiency and reliability, as any misalignment or improper fit can lead to significant performance issues.

Role of Part 4010891 Lubricating Oil Supply Tube in Engine Systems

The 4010891 Lubricating Oil Supply Tube is an essential component in the efficient operation of various engine systems. It is responsible for delivering a consistent flow of lubricating oil to key components, ensuring their smooth and prolonged functionality.

Integration with Cam Assembly and Follower

In the cam assembly, the lubricating oil supply tube plays a significant role by providing necessary lubrication to the cam and its follower. This lubrication reduces friction between the cam and follower, which are in constant motion against each other. Proper lubrication ensures that the cam can rotate smoothly, minimizing wear and tear on both the cam and the follower. This, in turn, contributes to the overall efficiency and longevity of the engine 2.

Contribution to Oil Assembly Plumbing

The lubricating oil supply tube is also a vital part of the oil assembly plumbing system. It connects various components within the oil assembly, facilitating the circulation of oil throughout the engine. This continuous flow of oil is essential for maintaining optimal temperature and pressure levels within the engine, which are vital for its performance and durability.

Ensuring Smooth Operation of the Follower

The follower, which is a component that interacts directly with the cam, relies on a steady supply of lubricating oil to function effectively. The 4010891 tube ensures that the follower receives the necessary lubrication, which is crucial for its operation. This lubrication helps in reducing the noise and vibration that can occur due to metal-on-metal contact, leading to a smoother and more reliable engine operation.

Supporting the Cam’s Performance

The cam, a rotating component that controls the timing of the engine’s valves, also benefits from the lubrication provided by the 4010891 tube. Consistent lubrication helps in maintaining the cam’s shape and surface, which is essential for its precise operation. This precision is key to the engine’s performance, as it directly affects the timing and efficiency of the valve operations.

Conclusion

In summary, the 4010891 Lubricating Oil Supply Tube is a fundamental component in the lubrication system of an engine. Its role in supplying oil to the cam assembly, follower, and other critical components ensures that these parts operate smoothly and efficiently, contributing to the overall performance and longevity of the engine.
