This wedge is a replaceable wear component in the cleaning system of a self-propelled forage harvester or combine. It is positioned to guide material flow and protect the underlying structure from abrasion. As the wedge wears, the gap it controls increases, reducing cleaning efficiency and allowing crop residue to bypass the intended path. The manufacturer machines this wedge to match the original profile so it seats correctly in the mounting pocket without requiring shimming. On installation, ensure the wedge is fully seated and the retaining hardware is tightened to the specified torque.
