I don't have any experience with Shopsmith before this, so I don't recognize whether this pulley is something unique or if that item in the center is part of a mechanism that holds the pulley to the headstock shaft.
Thanks for any insight anyone has for me.

I can't remember where I bought this one, but Harbor Freight sells pullers, as do other places like Graingers, McMaster.
If you own a Shopsmith or any machinery at all, you will find future uses for a puller.

The machined portion of the drive sleeve in the first photo is where the bearings go. There is a spacer between them that the set screw in the head stock engages to hold the whole assembly in the head stock.
A good soak with penetrating oil and a puller should work. The pulley is cast and fairly fragile so be careful of the force applied.

and I agree with John. Patience can be the key here to a good outcome. Allow the penetrating oil to do its job before trying to use a puller. If your pulley had two set screws holding it on, which is not common, it could be the extra set screw "digging" into the Drive Sleeve that could be keeping it from coming off.A good soak with penetrating oil and a puller should work. The pulley is cast and fairly fragile so be careful of the force applied.
The puller SteveMaryland showed in his post may work fine but I prefer one like the set shown below. Again, these pulleys can be fragile and this type of puller can distribute the pressure all around the pulley edge instead of just three spots. You will also need something to push against since the Drive Sleeve itself has the splined bore. A piece of wood doweling can be helpful here as it will avoid metal to metal contact on the Drive Sleeve and possible damage to the splined bore.
_ The above Gear Puller set is an example and you may need a larger puller set than shown to accommodate the 4" step of the Drive Pulley.

Model 10ER S/N R64000 first one I restored on bench w/ metal ends & retractable casters.
Has Speed Changer, 4E Jointer, Jig Saw with lamp, a complete set of original accessories & much more.
Model 10E S/N 1077 oldest one I have restored. Mark 2 S/N 85959 restored. 10E S/N 1076 & others to be restored.
The last picture in John's post makes it clear what I am seeing in the center of the pulley-the shaft has that six-sided star pattern. I'll buy a gear puller and start soaking the assembly with some oil.
I'm guessing that this pulley on the headstock is the original. The pulley on the motor appears much newer and it must be an upgrade. It feels and looks finely machined. It has on the inside of the back of the pulley a small blob of what looks like epoxy (?), which I assume was used to balance the pulley.
My 10ER does have two set screws holding this pulley on to the shaft. Both have been removed (in the picture above). Now that you mentioned that two set screws (vs one set screw) is unusual, I will take a look at the other 10E I have that awaits restoration.
I have to say, now that I have spent some time on these two Magna Engineering tools, just how impressed I am with the simplicity of the engineering.
Having said that, it is not 100% correct. They are not an off the shelf item but, Skip Campbell of MKC Tools ( www.mkctools.com ) does custom make them. They are currently listed on his web site for $46.50 each.

Next project is learning what to do about the quill return spring. The spring on my 10ER is pretty weak and sloppy so I need to figure out what to do with that.

However weak does not compute. Insufficient tension does. It may just require adjusting. (another turn or two)
What do you mean by 'sloppy' ?
