Introduction To V Ribbed Belts

V ribbed belts, also known as cogged belts, are a type of belt drive that uses a series of ridges or “cogs” along the inner surface of the belt to increase the grip between the belt and the pulley ¹. This design allows for efficient power transmission from the engine to various components within the vehicle. V ribbed belts are commonly used in modern automotive and heavy-duty truck engines due to their durability, efficiency, and ability to handle high loads.

The Role Of Cummins Part #3288689 V Ribbed Belt In Truck Engines

This Cummins part is a crucial component in the operation of commercial truck engines.
