Awesome Brian! Glad I could help. There is a treasure trove of info on here if you know how to find it. I figured I would post pics for reference for myself and anyone else "new" like myself to look back on. i will do my best to keep going with the pictures. As you can see alot of people are very helpful with any questions or problems you may have.
Good luck with your rebuild!!

Out of curiousity, what happens if you do not turn your Shopsmith up to full speed before working on it? Is it just difficult to calibrate otherwise after?

It's a serious pain in the backside to get the belts off.

X2 on that! My switch died in the off position and I was on the low speed for drilling operations. It took me an hour to get the belts off. (My speed control is a bit dodgy and I couldn't get the sheaves to open up by spinning by hand) I wound up removing the eccentric bushing from the idler shaft and pulling that to release the tension from the pulleys so I could get the belts off to get the motor out of the way, to get at the switch.

Thanks Terry for the info! I had a quick question. Should the floating sheath just pull right off. Mine seems to be getting stuck at the lip where the stop ring seats. I don't want to force it and break it. Oh and anyone know the size of the stop ring? Mine went for a ride in the garage and I didn't see where it landed haha.

9/16" The type without the 'ears' works best.

Check for any burrs around the ring groove that may be snagging the sheave.

Sometimes the key is bent and makes removal 'less easy'.

BTW Did the spring go air born also?

:D

I also had one that the key wasn't bent but it was a little stuck in the sheave and slid nice in the shaft groove. When I pulled on the sheave the key acme with it and kept sticking a the end in just about the same area as your talking about. If this is it lube up the key in the sheave and hold the key in place while pulling on the sheave (yeah I know you need a third hand:rolleyes: )

If you leave the fan sheave set screw holding the key, it will not move with the floating sheave as it is removed.

Oh sure, just do it the easy way. Like the third hand is hard to grow or something.
