shaft completely inserts into the rear bearing in the rear of the hopper. The auger threads should be
accessible from the outside rear of the hopper.

hopper (this hopper only). * See below for wide hopper. For either hopper, turn coupling and make sure
pinwheel in properly installed and turns freely.
