(Figure 3).

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).

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).
Figure 5
Many models have side plates that are attached
by cap screws and lock nuts. Removing or at least
loosening one side plate will ease removal of the
auger assembly (Figure 6).
