This multi-rib belt transmits power from the engine to the drive system of the parent combine. It is a 6PK profile belt, meaning it has six longitudinal ribs that engage with corresponding pulleys to transfer torque without slipping. As the belt wears, it can lose tension and begin to slip, causing a loss of drive to the driven components and potential squealing. This Contitech belt is molded to the same cross-section and length as the original, so it maintains the correct tension range without requiring shimming or a different tensioner setting. When replacing, ensure the belt is routed correctly on all pulleys and that the tensioner is set to the manufacturer's specification.
