V Ribbed Belt 3104420 Compatibility with Cummins Engines

The V Ribbed Belt part number 3104420 is designed for compatibility with several Cummins engine models, including the ISX15 CM2350 X101, QSX15 CM2250 ECF, and QSX15 CM2350 X105. It ensures the efficient operation of ancillary systems such as the alternator, water pump, and air conditioning compressor.

Role of Part 3104420 V Ribbed Belt in Engine Systems

The 3104420 V Ribbed Belt is integral to the operation of various engine components. It transfers power from the engine to peripheral systems, ensuring they function in harmony with the engine’s operation.

Interaction with the Fan Drive

This part drives the fan drive, maintaining optimal engine temperature by connecting the crankshaft to the fan. This ensures the fan rotates at a speed proportional to the engine’s RPM, enhancing airflow over the radiator and preventing overheating.

Contribution to the Fan Drive Belt System

In systems with a separate fan drive belt, the V Ribbed Belt powers a series of pulleys connected to engine accessories, including the water pump. The water pump circulates coolant through the engine and to the radiator, where it is cooled before being recirculated. The V Ribbed Belt’s role is to ensure the water pump operates efficiently, supporting the overall cooling process that the fan drive facilitates.

Conclusion

The Cummins 3104420 V Ribbed Belt is a vital component in the power transmission network of an engine, directly influencing the operation of the fan drive and indirectly supporting the cooling system through its interaction with other engine accessories. Regular maintenance and proper installation are key to ensuring its efficiency and reliability.
