This V-belt transmits power from the engine drive pulley to the driven components in the combine's drive system. It is a multi-rib belt that engages with matching pulleys to transfer torque without slippage under load. A worn or stretched belt causes speed loss at the driven assembly, leading to reduced throughput or inconsistent operation of downstream mechanisms. The belt is manufactured by Gates to match the original cross-section and pitch length, ensuring correct tension and pulley contact without requiring shimming or modification. On replacement, verify the belt routing matches the original path and adjust tension to the specified deflection.
