This chain is the drive element for the inclined conveyor, which moves crop material from the header into the threshing mechanism. It transmits power from the drive sprocket to the conveyor slats, maintaining the correct tension and timing to keep the material flow consistent. A worn or stretched chain causes slat misalignment, leading to uneven feeding and potential blockages at the transition point. The original chain is manufactured to the same pitch and link geometry as the factory assembly, so it engages the sprockets without requiring shimming or modification. On installation, ensure the chain tension is set to the specified deflection and that the sprockets are aligned in the same plane.
