This chain is part of the inclined conveyor assembly that moves harvested material upward from the feeder housing into the threshing mechanism. It engages with the drive sprocket at the bottom of the conveyor and the return sprocket near the top, pulling the slats that carry the crop mat. As the chain stretches from load and wear, the pitch increases, which can cause the chain to skip over the sprocket teeth or produce a slapping noise against the conveyor floor. The manufacturer machines the link pins and bushings to the original profile, so the chain maintains the correct pitch for the sprocket geometry and does not require additional take-up adjustment beyond the normal tensioner range.
