Application in Cummins Engines

QSC8.3 CM850 (CM2850)

The QSC8.3 CM850 (CM2850) engine benefits from the use of the 5255743 drain tube. This part ensures that the oil is effectively drained from the engine’s oil pan, which is crucial for maintaining the engine’s lubrication system and preventing oil contamination.

QSL8.9 CM2150 L141

In the QSL8.9 CM2150 L141 engine, the 5255743 drain tube plays a similar role. It is essential for the proper functioning of the engine’s lubrication system, ensuring that the oil is drained efficiently and that the engine is protected from the harmful effects of old or contaminated oil.

QSL9 CM850 (CM2850)

The QSL9 CM850 (CM2850) engine also utilizes the 5255743 drain tube. This part is integral to the engine’s maintenance routine, as it allows for the regular and effective drainage of oil, which is vital for maintaining the engine’s performance and longevity.

By ensuring that the oil is properly drained, the 5255743 drain tube helps to maintain the engine’s lubrication system, which is essential for the smooth operation of the engine and the prevention of engine wear and damage.

Role of Part 5255743 Lubricating Oil Drain Tube in Engine Systems

The lubricating oil drain tube, identified by part number 5255743, is integral to the efficient operation of engine systems, particularly in relation to the breather and crankcase components.

In the context of the breather system, the lubricating oil drain tube facilitates the removal of excess oil that may accumulate within the breather assembly. This is essential for maintaining optimal airflow and preventing oil contamination, which can adversely affect engine performance. The tube ensures that any oil that has been drawn into the breather system is efficiently drained away, thereby preserving the integrity of the air-oil separation process.

Regarding the crankcase, the lubricating oil drain tube plays a significant role in managing oil levels. The crankcase is a critical component where engine lubrication oil is stored and circulated. Over time, oil can accumulate due to various factors such as condensation or overfilling. The drain tube provides a reliable pathway for this excess oil to be removed, ensuring that the crankcase does not become overfilled. This helps in maintaining the correct oil level, which is vital for the lubrication of moving parts within the engine, reducing wear and tear, and enhancing overall engine longevity.

Additionally, the efficient drainage of oil via the lubricating oil drain tube contributes to the reduction of oil sludge formation. Sludge can build up over time and lead to decreased engine efficiency and potential damage. By ensuring that excess oil is consistently drained, the tube helps in keeping the engine clean and operating at peak performance.

Conclusion

In summary, the lubricating oil drain tube (part 5255743) is a vital component in the maintenance of both the breather and crankcase systems, ensuring that these elements function correctly and contribute to the overall reliability and efficiency of the engine.
