Many thanks! I just took my sheave to the hardware store and picked out a piece of plumbing tubing and cut it to length. It seems to work well, and the main spring fits over it nicely.

I got the motor housing all reassembled, and I'm astounded how well it runs now all cleaned ...

I like the sleeve idea. If I can't find the right dimensions for it at the hardware store, I'll try the JB Weld technique.
Thanks!

After cleaning away the grease on the bottom fan blade sheave I found the set screw. It must have gotten loose to cause the scraping against the housing, as I didn't have to loosen it to remove the sheave. I'll be sure to tighten it when I reinstall the sheave.

DLB, you're right about spring ...

Ok, thanks. The key is actually straight and not bent. In the photo it's riding high and coming out of its slot. I'm wondering if a thin hose clamp would hold up and keep that key from sliding out like that over time. I thought about a zip tie, but I'd like to honor this 65 year old machine and not ...

Not understanding about the key stock or 2nd retaining ring. There's no groove at the base of the axle for a retaining ring.

Well, it was penetrating oil to the rescue! Plus vice grips and persistence (and a little harsh language to boot). Once the hub came off and I CAREFULLY let the spring go, I can see there's a groove for a snap ring, so it's back to Ace Hardware to get one. The collet is cracked from the key weigh ...

Thanks for clarifications and the diagram. Very helpful.

Yes, I've compared it to ones on my bandsaw and scrollsaw and it's the same. I assume a previous owner put it on. I'd like to replace it with a proper fitting, so I've been scanning photos to find one. There's no spring clip behind it to hold the spring on as far as I can tell. I'll try some ...

This is all great info. I've continually had problems when I restart my Mark V 500 when set at high speed. I thought I was supposed to shut it off set to high speed so as to not stretch the belts too much while it sits idle. Since my belts are still in good shape, (and I'm getting more adept at ...

Be careful. I can tell you from experience that hub on the end might come shooting off at any moment.


Yes indeed, I'm being very careful with it. I can tell the strenth in that spring when I press it down. FYI, I used a couple of wire loops around the end of my press-down board wrapped around ...
