Having done all this, the auger shaft will not move. I have even used a heavy hammer with a block of wood so as not to damage the shaft, and it will not budge. The shaft does move side to side in the bearing, moving the auger assembly from the front. So it appears to be loose, but will not move out of the bearing. Being a machine repair man for over 30 years, this should be very easy. The only thing I can figure out is to heat the shaft and or bearing with a torch and see if it will move. I can always replace the bearing. I just want to make sure there is nothing else holding in that shaft.
