This lower housing encloses the lower section of the grain elevator on a combine harvester. It sits at the base of the vertical elevator leg, directing grain flow from the clean grain auger into the elevator chain and paddles. The housing provides a sealed path that prevents grain loss and protects the chain and sprocket from debris. Over time, the housing can develop cracks or wear at the mounting points due to vibration, leading to grain spillage and misalignment of the elevator chain. The manufacturer machines the housing to match the original geometry, ensuring proper alignment with the elevator boot shaft and the clean grain auger outlet. On replacement, transfer the existing seals and gaskets to the new housing, and tighten the mounting bolts to the specified torque.
