Cummins Molded Hose Assembly Part 3638280 in Engine Applications

The Cummins Molded Hose Assembly part number 3638280 is a component in the engine systems of the QSK50 CM2150 MCRS and QSK50 CM2350 K108 engines. This part is integral to the engine’s operation, ensuring the efficient transfer of fluids and gases within the engine’s system.

QSK50 CM2150 MCRS Engine

In the QSK50 CM2150 MCRS engine, the molded hose assembly part 3638280 is designed to connect various fluid lines, ensuring that the engine’s hydraulic and cooling systems function optimally. This hose assembly is engineered to withstand the high pressures and temperatures typical of engine environments, providing a reliable seal that prevents leaks and maintains system integrity.

QSK50 CM2350 K108 Engine

Similarly, in the QSK50 CM2350 K108 engine, the molded hose assembly part 3638280 plays a role in the engine’s fluid management systems. This component is specifically designed to fit the unique layout and requirements of the QSK50 CM2350 K108 engine, ensuring that all fluid lines are securely connected and that the engine operates at peak efficiency. The durability and precision of the hose assembly are essential for maintaining the engine’s performance and longevity.

Both engines benefit from the use of this molded hose assembly, as it provides a seamless integration into the engine’s design, ensuring that all fluid pathways are properly sealed and maintained. This part is a testament to Cummins’ commitment to quality and reliability in engine components.

Role of Part 3638280 Molded Hose Assembly in Engine Systems

The molded hose assembly, part 3638280, is integral to the efficient operation of several engine systems. It facilitates the connection between the breather and the crankcase, ensuring that the ventilation and pressure equalization processes function smoothly.

In the breather system, the hose assembly allows for the release of excess pressure and the intake of fresh air. This is essential for maintaining optimal air-fuel ratios and preventing the buildup of harmful gases within the engine compartment.

When connected to the crankcase, the hose assembly plays a significant role in the crankcase ventilation system. It helps in evacuating blow-by gases—a mixture of air, fuel, and combustion byproducts that escape past the piston rings—from the crankcase. This not only reduces the risk of contamination in the engine oil but also minimizes the emission of pollutants into the atmosphere.

The seamless integration of part 3638280 within these systems underscores its importance in preserving engine health, enhancing performance, and ensuring compliance with environmental regulations.

Conclusion

The 3638280 Molded Hose Assembly is a critical component in the operation of commercial trucks and specific engine systems. Its robust construction, precise design, and reliable performance contribute to the efficient transfer of fluids, maintaining engine health, and ensuring compliance with environmental standards. Regular maintenance and proper installation are key to maximizing the benefits of this Cummins part.
