Mark 5 "greenie" mid 1950's Franklin Electric motor work

I recently got my hands on an old Shopsmith Mark 5 "greenie" and have been slowly disassembling it. I've run into a stopping point with the Franklin Electric motor where I am just not sure at all what to do. I did search around and found the this reference useful, but that's about it.

First question is, how do I get the sheaves off the motor? There's a large bolt holding the spring down which is different than all of the motors I've seen disassembly instructions for. Pictures for reference:

Second question: when I originally bought the Shopsmith, it would start up just fine but once up to speed it'd trip the breaker and shut off. After getting the motor on it's own, it made a high pitched squealing noise (like metal rubbing on metal). After trying to run it again to get a video of it, it stopped making this noise. I have no idea what's going on with this guy! Youtube video for reference: https://www.youtube.com/watch?v=Evaci8DmZ4A

Any insights on how to get the sheaves off and what may be going on with my motor would really be appreciated. Let me know if there's any extra information I can give!

Thanks!

Mine made the high pitched squealing noise, it was the bearings inside the motor that were shot.

Mine did the exact same thing though. Once I got the drive belt off from it it squeaked a little, but stopped when there wasn't a load on the sheaves.

Once I replaced the motor bearings, it ran smooth. Unfortunately, my motor was a GE and just a retaining clip / washer holding the sheaves on so I can't help you there.

A guy named Jacob Anderson sells DVD's on Ebay. I bought his DVD's and they were a great help when rebuilding my headstock / motor. He walks you through all the steps. They aren't too expensive either.

Between the videos and emailing Bill Mayo for advice / parts the job was super easy.

My first guess re the squeal would be bearings.

Re the spring/nut, be aware it has a left hand thread. Be careful, provide a way for the spring to expand gradually(under control). Getting it back on will be 'fun'. I set the motor on a wooden platform placed on the way tubes, and used the quill with a socket wrench in a chuck to remove/reinstall the nut.
