Components of Cummins Water Pump Kit 5473174

Rectangular Ring Seal (3906698)

The rectangular ring seal, identified by the part number 3906698, is a critical component within the Water Pump Kit. This seal is designed to provide a tight and reliable connection between various parts of the water pump assembly. Its primary role is to prevent coolant leaks, ensuring that the cooling system maintains optimal efficiency. The rectangular shape of the seal allows it to fit snugly into the designated grooves or channels within the pump housing and impeller, thereby creating a barrier that keeps the coolant contained within the system. The material of the seal is typically chosen for its durability and resistance to the corrosive effects of coolant, ensuring long-term reliability and performance.

Water Pump (5477735)

The water pump, designated by the part number 5477735, is the central component of the Water Pump Kit. This pump is responsible for circulating coolant throughout the engine’s cooling system. It operates by using an impeller driven by a belt connected to the engine’s crankshaft. As the impeller rotates, it creates a flow of coolant that is directed through the engine block and cylinder head, absorbing heat generated by the combustion process. The efficient circulation of coolant is essential for maintaining the engine’s operating temperature within a safe range, preventing overheating and potential damage. The water pump’s design ensures that it can handle the pressures and temperatures within the cooling system, providing consistent performance over the engine’s lifespan.

Conclusion

The Cummins 5473174 Water Pump Kit is a vital component for maintaining the efficiency and reliability of heavy-duty truck engines. Its design, featuring robust construction and precision-engineered components, ensures optimal coolant circulation and engine temperature management. Regular maintenance and timely troubleshooting are essential for maximizing the kit’s performance and longevity, contributing to the overall operational efficiency of commercial trucks.
