I'm a newbie working on pumps and have only done a couple smaller projects. One I'm working on needs new numbers on the price wheels. I have the number stickers, but can't figure out how you get access to the entire wheel to put them on. Before I start pulling every screw and pin in an effort to get to them, is there a trick or efficient way to get the wheels off or where they can rotate freely?

Thanks!
