Compatibility with Cummins Engines

This part is a critical component in the engine cooling system. It is designed to securely hold water tubes in place, ensuring efficient heat transfer and maintaining optimal engine temperature.

QSK19 and CM850 Engines

The QSK19 and CM850 engines, both part of Cummins’ QSK series, are high-performance engines designed for heavy-duty applications. The Water Tube Bracket fits seamlessly into these engines, providing a robust mounting solution that withstands the rigors of demanding environments. Its precision engineering ensures that the water tubes remain aligned and secure, contributing to the overall reliability and longevity of the engine.

MCRS Engines

The MCRS engines, another variant within Cummins’ lineup, are engineered for marine applications. The Water Tube Bracket is specifically designed to meet the unique requirements of these marine engines. Its durability and resistance to corrosion make it an ideal choice for environments where exposure to saltwater and other harsh conditions is common. This bracket ensures that the water tubes are properly positioned, facilitating efficient cooling and protecting the engine from overheating.

Grouping of Engines

The QSK19, CM850, and MCRS engines share common design principles and engineering standards, which allows the Water Tube Bracket to be used across these models. This compatibility simplifies maintenance and repair processes, as technicians can use a single part for multiple engine types, reducing inventory costs and ensuring consistent performance.

Role of Part 4959403 in Engine Systems

This Cummins part is an essential component in the integration and functionality of various engine systems, particularly in the context of plumbing and aftercooler water systems.

Integration with Plumbing Systems

In plumbing systems associated with engine operations, the Water Tube Bracket secures and supports water tubes that facilitate the flow of coolant or water. This bracket ensures that the tubes are held firmly in place, minimizing the risk of vibrations or movements that could lead to leaks or inefficiencies in the coolant flow. Its role is significant in maintaining the structural integrity of the plumbing system, allowing for consistent and reliable coolant distribution throughout the engine.

Function in Aftercooler Water Systems

In aftercooler water systems, the Water Tube Bracket plays a key role in supporting the water tubes that are integral to the cooling process of compressed air. After the air has been compressed, it is typically very hot, and the aftercooler is designed to reduce its temperature before it enters the engine. The Water Tube Bracket ensures that the water tubes within the aftercooler are properly aligned and secured. This alignment is vital for the efficient transfer of heat from the compressed air to the water, enhancing the overall performance and efficiency of the engine.

By securing the water tubes, the Water Tube Bracket contributes to the stability and effectiveness of both the plumbing and aftercooler water systems. It ensures that these systems operate smoothly, with minimal risk of component failure or performance degradation.

Conclusion

The Water Tube Bracket (Part #4959403) by Cummins is a testament to the company’s dedication to providing reliable and efficient solutions for the commercial trucking sector. Its role in the engine cooling system, combined with its durable construction and precise engineering, underscores the value of using genuine Cummins parts for optimal engine performance and longevity ²³.
