I've seen a few threads here from folks who've replaced the auger motor on the enviro empress. Could someone walk me through it. It looks as though there is simply a collar with a locking screw on the shaft, but loosening the screw has little effect. There is also a framework with some padding to keep the motor from making too much noise. This is attached through the hopper with 4 screws. The motor is not visibly attached to this, but I am thinking that there may be a second collar & that I need to remove this entire assembly? On the other hand, I don't want to accidentally pull out the auger so I'd like to know what I'm doing before I begin!
