2.On the forward side of the auger pulley is 1 or 2 set screws, depending on the model, which must be loosened. Use the square end of a 3/8” socket extention. Note: The pulley is keyed to the shaft and will be removed later (Figure 4).

3.In the center of each side plate are either two or four cap screws (depending on the model). These go into the bearing that supports each side of the auger. Remove the cap screws (Figure 5).
