Adhering to recommended inspection intervals will help maintain the tube’s effectiveness ².

Cummins Engine Compatibility with Lubricating Oil Drain Tube Part 5333380

The Cummins part number 5333380, which is a Lubricating Oil Drain Tube, is designed to fit into several of Cummins’ engine models. This part is integral to the maintenance and operational efficiency of these engines by ensuring proper oil drainage and preventing oil contamination.

B6.7 CM2670 and B164C Engines

The B6.7 CM2670 and B164C engines are part of the Cummins B-Series engine family. These engines are known for their robust design and reliability, often used in various industrial and commercial applications. The lubricating oil drain tube part 5333380 is specifically engineered to fit these models, ensuring that the oil is efficiently drained from the engine’s sump, thereby maintaining optimal engine performance and longevity ².

QSB6.7 CM850 (CM2850) Engines

The QSB6.7 CM850 (also known as CM2850) engines are part of the Cummins QSB Series, which are designed for heavy-duty applications. These engines are widely used in agricultural, construction, and industrial machinery due to their durability and power. The lubricating oil drain tube part 5333380 is compatible with these engines, facilitating the removal of used oil and preventing the buildup of contaminants that could otherwise degrade engine performance ².

QSB7 CM2880 B117 Engines

The QSB7 CM2880 B117 engines are another variant within the Cummins QSB Series, known for their high torque and efficiency. These engines are typically used in heavy-duty applications such as mining, construction, and marine industries. The lubricating oil drain tube part 5333380 is designed to fit these engines, ensuring that the oil is effectively drained and the engine remains clean and well-lubricated ².

Role of Part 5333380 Lubricating Oil Drain Tube in Engine Systems

The 5333380 Lubricating Oil Drain Tube is a component in the maintenance and operation of engine systems, particularly in relation to the breather and crankcase components.

In the context of the breather system, the drain tube facilitates the removal of accumulated oil and contaminants that may enter the breather system. The breather allows air to enter and exit the crankcase, maintaining pressure equilibrium and preventing the buildup of harmful gases. Over time, oil vapors and other contaminants can accumulate within the breather system. The drain tube provides a pathway for this oil to be expelled, ensuring that the breather system operates efficiently and does not become clogged ⁴.

Regarding the crankcase, the drain tube plays a significant role in maintaining the integrity of the lubrication system. The crankcase houses the crankshaft and other moving parts that rely on a consistent supply of clean oil for lubrication. As oil circulates through the engine, it picks up contaminants and degrades over time. The drain tube allows for the periodic removal of this used oil, ensuring that fresh, clean oil can be introduced into the system. This helps in preserving the lubrication quality, reducing wear on engine components, and enhancing overall engine performance ³.

Conclusion

The 5333380 Lubricating Oil Drain Tube is integral to the efficient operation of both the breather and crankcase systems, contributing to the longevity and reliability of the engine. Proper installation, maintenance, and troubleshooting of this part are essential for ensuring optimal engine performance and longevity ²³⁴.
