This wedge is a locating and alignment component for the feeder house assembly on a forage harvester or combine. It sits between the feeder housing and the machine frame, providing a precise interface that maintains the correct angle and position of the material feeding unit relative to the cutting or pickup attachment. A worn or missing wedge allows the feeder house to shift, causing misalignment that leads to accelerated wear on the drive chains, sprockets, and the feed-roll bearings. The original wedge is machined to the same thickness and taper as the factory assembly, so no shimming or additional adjustment is needed during installation. On reinstall, clean the mating surfaces and torque the mounting bolts to the specified value.
