This bracket is part of the cleaning unit on a combine harvester. It provides a mounting point for the cleaning-shoe components, maintaining the correct geometry between the sieve frame and the oscillating drive linkage. A bent or cracked bracket alters the sieve stroke, reducing cleaning efficiency and allowing material to carry over the sieves. This original part is formed to the same gauge and hole spacing as the factory assembly, so no shimming or re-drilling is needed during replacement.
