These engines, which are part of the higher power output range, require a belt that can maintain performance under increased load and stress. The 4900941 V-Belt is engineered to meet these requirements, providing a reliable connection between the engine’s components and ensuring efficient operation.

Grouping of Engines

When considering the compatibility of the V-Belt 4900941, it is useful to group the engines based on their power output and operational characteristics. The A1400 and A1700 engines, being in the lower power range, share similar design and operational parameters, making them suitable candidates for the same V-Belt. On the other hand, the A2000 and A2300 engines, with their higher power output, also benefit from the same V-Belt due to the shared engineering principles and performance needs.

This compatibility ensures that users can confidently select the V-Belt 4900941 for their Cummins engines, knowing it is designed to fit and perform optimally across the specified models.

Role of Part 4900941 V-Belt in Engine Systems

The part 4900941 V-Belt is integral to the efficient operation of various engine systems. It primarily functions to transmit power from the engine to auxiliary components, ensuring they operate in sync with the engine’s performance.

Interaction with the Belt System

The V-Belt, identified by part number 4900941, interfaces with the belt system to facilitate the transfer of rotational force. This interaction is essential for driving multiple engine accessories that rely on consistent power delivery. The V-Belt’s design allows it to grip the pulleys effectively, minimizing slippage and ensuring that power is transmitted efficiently across the belt system.

Connection to the Fan Drive

In engine systems, the V-Belt plays a significant role in the operation of the fan drive. The fan drive is responsible for regulating the engine’s temperature by controlling the speed of the cooling fan. The V-Belt connects to the fan drive pulley, allowing the engine to power the fan. As the engine runs, the V-Belt rotates the fan drive, which in turn adjusts the fan’s speed based on the engine’s thermal needs. This ensures that the engine maintains optimal operating temperatures, preventing overheating and potential damage.

Overall Functionality

By linking the engine to both the belt system and the fan drive, the part 4900941 V-Belt ensures that these components work harmoniously. Its reliable performance is key to the smooth operation of the engine, contributing to the durability and efficiency of the entire system.

Conclusion

The Cummins 4900941 V-Belt is a critical component in the operation of commercial trucks, ensuring efficient power transmission to various auxiliary systems.
