This cover plate sits on the inclined conveyor of the parent combine, protecting the feed chain and slats from wear as crop material enters the threshing mechanism. It is the replaceable wear surface that absorbs abrasion from the moving crop mat, preventing damage to the underlying conveyor structure. When the plate thins or develops grooves, the feed chain can contact the conveyor frame, causing accelerated wear and reduced feeding efficiency. The manufacturer machines this part to the original profile so it seats flush against the conveyor rail without requiring additional shimming. On installation, use new fasteners and tighten them evenly to prevent the plate from lifting during operation.
