Cummins®

The 3040661 V Ribbed Belt, manufactured by Cummins, is a component designed for use in commercial trucks. It plays a role in the operation of these vehicles by facilitating the transfer of power from the engine to various ancillary components. Cummins, a well-established name in the commercial vehicle industry, ensures that this belt meets the rigorous demands of heavy-duty applications.

Basic Concepts of V Ribbed Belts

V Ribbed Belts are characterized by their trapezoidal cross-section, which allows them to fit snugly into corresponding pulleys. This design enhances grip and reduces slippage compared to flat belts ¹. V Ribbed Belts are constructed from multiple layers, including a durable core and a flexible outer layer, which together provide strength and flexibility. They differ from other belt types, such as flat or timing belts, in their ability to transmit higher power with less belt width, making them ideal for applications requiring efficient power transfer.

Role of the 3040661 V Ribbed Belt in Truck Operation

In the context of a commercial truck’s engine system, the 3040661 V Ribbed Belt serves to drive several key components. It is responsible for powering the alternator, which generates electricity for the vehicle’s electrical systems. Additionally, it drives the water pump, which circulates coolant through the engine to manage temperature. The belt also operates the air conditioning compressor, ensuring the comfort of the vehicle’s occupants. By efficiently transferring power to these components, the belt contributes to the overall functionality and performance of the truck.

Key Features of the 3040661 V Ribbed Belt

The 3040661 V Ribbed Belt is designed with specific characteristics to enhance its performance in demanding environments.
