buy a flywheel puller for blasters. its a 20 dollar tool that you thread into the threads on the inside of the flywheel and turn the other bolt it presses it off. if there nice, just bring it to them on your trailer or whatever, with that cover off and the nut off and just ask em if they have a sec to do it. maybe they have the tool, who knows. if they do im sure they got the time for 2 mins to pull it off. i know the shop im at wouldnt charge for that.
