This feeder house guide assembly positions and guides the moving components of the material feeding system as crop material enters the threshing mechanism. It mounts within the feeder house structure, maintaining alignment between the feed chain or slats and the surrounding housing panels. Wear in this guide allows lateral movement of the feed mechanism, which can cause uneven feeding, chain slap against the housing, and accelerated wear on adjacent wear strips and sprockets. This assembly is manufactured to the original geometry so that it maintains the correct clearance between the moving feed components and the stationary housing without requiring shimming or modification during installation.
