This V-belt transmits power from the engine or main drive to the cleaning system of a combine harvester. It connects the drive pulley to the fan or shaker assembly that moves air and sieves to separate grain from chaff. A worn or slipping belt reduces cleaning fan speed, leading to incomplete separation and increased grain loss over the sieves. As an original-manufacturer component, the belt is constructed to match the original cross-section and length, which ensures proper tension and pulley contact without requiring shimming or belt-tensioner adjustment. On installation, verify belt tension per the machine specification and replace any worn pulleys at the same time.
