2007 honda ricon rear brakes issue.

Seems I’m having hell with these brakes finaly got my 03 rancher brakes going now I’m working on my 07 Rincon and cant get the dam cover off the back that expsoes the inside of the drum! I took on the 2 big nuts and move them back and the washers but that dam plate wont come off it moves out and gets stuck it has some kinda ring in it that I cant get to slide out! it was seized up at first and I was able to get it to spin using a air chisel but it still wont slid off the shaft. any ideas on how to get it off? I was thinking maybe pulling the whole rear end off from left to right and putting it in a press or would that be a bad idea?
