Blower Snout Disassembly

I need to take apart the 7-inch snout off of my ssi. Single bearing, driveshaft is part of the pulley flange. Looks like maybe a spirolock type deal on the inside of the bearing? Other than that I'm guessing it's all pressed together??

 

Ok figured it out with a little help. Spirolock type thing has to come out from behind the bearing. I assume there is a tool for this but can't imagine what it looks like. Three screw drivers, an oring pick and a lot of tongue chewing works with some patience.
