This V-belt transmits power from the drive pulley to the driven pulley in the parent combine’s drive system. It is a three-rib belt with a wedge profile that engages matching grooves on both pulleys, providing positive traction without slippage under varying load. A worn or stretched belt causes speed loss at the driven component, leading to uneven material flow or reduced throughput. The belt is manufactured to the original cross-section and length specifications so that it maintains the correct tension range without requiring shimming or pulley adjustment. On installation, verify that the belt seats fully in each pulley groove and that the tensioner is set to the manufacturer’s specification.
