Today I finished pressing out all the bearings of my three headstocks. I was on a roll after realizing I suffered a short misplacement of my head in thinking there was a carefully cut spacer on the two bearing quill.
So after separating the quill, I moved onto the control sheave. Of all the bearings I had pulled, the control sheave bearing seamed to be the driest. The control sheave bearing was simply pushed in & then hit with a pin punch either 7-8 times on the end on my older sheaves or 4 times on the side of the newer ones.
I found the bearing easily pushed out. Next I squeezed the ends of the piece which was in the center of the bearing & pushed that out. All in all a simple process. I'm not sure then why the control sheaves are considered non-reparable, unless it is because of the uniqueness of the swivel.
I'm going to order some 637Z or equivalent bearings and see what happens.

Control Sheave Bearing
The control sheave bearing is a Fafnir 35KDD 5mm ID, 19mm OD and 6mm width. I buy them from http://www.ebatmus.com
The 627Z is for the bandsaw auto-track roller bearings (2) and has been suggested as a replacement for the upper and lower blade guide roller bearings.
