You can see the shims in the pictures. They're on the shaft slid all the way to the back. Yes I am wanting to reduce the air gap, just can't seem to get them to slide off. Thanks,

I hate to ask complete noob and dumb questions, but can someone tell me why I can't get the shims to slide off this compressor shaft? Short of taking it off and trying to shake them out?
