Thank you for all the tips and links, they are all very helpful. I have managed to separate everything except for the 2 headstock bearings and spacer from the shaft assembly that sits behind the headstock pulley (see 1st image). I have used an inordinate amount of penetrating oil, but nada as far as any movement what so ever. Do you think the bearing puller that Harbor Freight sells would work to remove these bearings? Other than this the only part that is still not separated is the large nut and bolt that are on the tailstock that would hold the live tailstock center when using the Shopsmith as a lathe. I don't know if I'm explaining this well, so see the 2nd image with the arrow. Again a lot of penetrating oil with no result, any tips on separating that?
Thanks,
Joe

I ran into some of these same issues when restoring my 10ERs. The Harbor Freight bearing puller should work just fine. It's what I have and use and I wish I had it when I was first doing my restorations!
On my 10ER that I have dedicated as a lathe, I never could get the pulley off the shaft on the headstock. So I just left it there and worked around it the best I could. Last weekend I was working on turning a big chunk of wood (I've only recently gotten in to turning on the lathe) and the part kept catching and stopping. At first I was thinking it was a motor issue and it just didn't have enough power. Then I thought perhaps the belt was slipping. After investigation, I discovered the pulley had come loose on its shaft and it could slip on and off with ease. I took it off, cleaned up the shaft, redressed the flat, re-installed the pulley (using blue locktite on the set screws).
I remember the center holder on the tailstock required a good bit of elbow grease. A combination of Kroil, heat, good wrenches, and a little time.

Getting the pulley off took awhile but I finally got it off. Speaking of the pulley I have a question about that, there are large chips on both my motor and headstock pulleys so I
was going to get the upgrade ones that are 44.50 each on MKCTools.com but my pulleys appear different. My motor pulley is actually 2 parts and has 4 steps (the first 3 are identical to the headstock pulley, but the 4th is larger). The motor pulley on MKC tools's site only has 3 steps.

The 10ER manual describes a 4-step pulley as part of the Jointer Mounting Kit for mounting the jointer to the 10ER. But I don't know anything about it being 2 parts. How are the parts divided? Is one part the original 3-step pulley and someone possibly added a single larger pulley? Or is it two 2-step pulleys?

The picture shows the original Magna drive kit for the 4E jointer. The 3 step pulley is not the original. The original pulley bore is 5/8". The bore on the new pulley is 13/16 I think which is the same as the head stock pulley. That is required to accommodate the added diameter provided by the sleeve and the shaft extension needed to mount the jointer drive pulley. The shaft extension is required because the motor shaft is not long enough to add another pulley.

Here is a thread where I replaced my 10ER's bearings:

That is a very rare item. It took me years of watching eBay to get the set I have and it is the only complete set I have seen on eBay. Of course if you don't have the jointer and head rest it is not needed. The jointer and head rest are fairly rare also but they do come up on eBay from time to time.

No I don't have the jointer and the larger pulley has a chip missing. But I will save it, maybe I can weld a piece of aluminum to the gap and shape it, or cut a piece off the headstock pulley to weld to it since that pulley is chipped as well and needs replacing. Then if i find a jointer I'm good to go.
