Compatibility with Cummins Engines

The Water Transfer Hose, identified by the part number 4936792, is compatible with various Cummins engines, including the K38 and K50 engine series. This hose is designed to facilitate the transfer of water within the engine’s cooling system, ensuring efficient heat dissipation and maintaining optimal operating temperatures ².

K38 Engine Series

In the K38 engine series, the Water Transfer Hose (4936792) is engineered to withstand the high pressures and temperatures typical of the K38 engine, ensuring durability and reliability. It connects various points within the engine’s cooling system, allowing for the smooth circulation of coolant and preventing overheating ².

K50 Engine Series

Similarly, in the K50 engine series, the Water Transfer Hose (4936792) is integral to the engine’s cooling system. The K50 engines, known for their robust performance, require a hose that can handle the demanding conditions of their operation. The part 4936792 is specifically designed to fit seamlessly into the K50 engine’s cooling pathways, ensuring that the coolant flows efficiently and the engine operates within its optimal temperature range ².

Role of Part 4936792 Water Transfer Hose in Engine Systems

The 4936792 Water Transfer Hose is an essential component in marine engine systems, facilitating the efficient transfer of water between various parts of the engine. This hose is integral to the operation of the raw water pump and the seawater pump, ensuring a consistent and reliable flow of water for cooling and other essential functions ³.

Integration with Raw Water Pump

The raw water pump relies on the 4936792 Water Transfer Hose to draw water from the surrounding environment, whether it be seawater or freshwater, and circulate it through the engine’s cooling system. The hose connects the intake side of the raw water pump to the seawater pipe mount, creating a sealed pathway for water to travel. This ensures that the pump can effectively draw in water and deliver it to the engine components that require cooling ³.

Connection to Seawater Pipe Mount

The seawater pipe mount serves as the entry point for water into the engine system. The 4936792 Water Transfer Hose is connected to this mount, allowing for a direct and unobstructed flow of seawater into the raw water pump. This connection is vital for maintaining the integrity of the water transfer process, as any leaks or disruptions in the hose can lead to inefficient cooling and potential engine damage ³.

Supporting Seawater Pump Functionality

In systems where a seawater pump is used in conjunction with the raw water pump, the 4936792 Water Transfer Hose plays a supporting role. It ensures that the seawater pump can effectively transfer water to areas of the engine that require additional cooling. This might include the heat exchanger, where the transferred water helps to dissipate heat from the engine’s lubricants and other fluids ³.

Ensuring Efficient Water Transfer

The efficient transfer of water is paramount in marine engine systems to prevent overheating and ensure optimal performance. The 4936792 Water Transfer Hose is designed to withstand the pressures and temperatures associated with engine operation, providing a durable and reliable connection between the raw water pump, seawater pump, and seawater pipe mount. Its role in maintaining a consistent water flow is fundamental to the overall efficiency and longevity of the engine system ³.

Conclusion

The Cummins 4936792 Water Transfer Hose is a critical component in the cooling systems of heavy-duty trucks and marine engines. Its durable construction, efficient design, and compatibility with various Cummins engines make it an essential part for maintaining optimal engine performance and longevity. Regular maintenance and proper installation are key to ensuring the continued reliability of this Cummins part.
