replace motor shaft sleeve on Kitchenaid food processer

I have a Kitchen Aid KFP 670 food processor. Motor shaft sleeve is stripped out. I need to replace it, but cannot figure out how to remove it from the motor shaft. Afraid I’ll break the housing or flanges on the housing if I try to pry it up.
The food processor works great otherwise. I realize this is a blender forum, but didn’t find a food processor forum-thought this was closest fit. Any help available would be greatly appreciated.
