Joe, that was one of John's first posts http://www.quiltingboard.com/vintage...s-t264590.html Since you asked specifically about the clutch and I know you have dial-up, I'll post the pertinent information here, too.

*** Clutch or Stop-Motion - When the clutch knob is removed, it exposes some unusual components, most notably three ball bearings in a ring carrier. I was fortunate enough to have read about these ball bearings somewhere and knew of them in advance. It is best to disassemble this with as close to a handwheel-up orientation as possible, so that the ball bearings don't fall out and get away from you.

The clutch assembly may be seen with the clutch knob removed. First the 3 ball bearings need to be removed, then the ball bearing carrier, then the clutch washer. After this, the handwheel can be removed.

It has the normal clutch washer, but with only one tab. The clutch or stop-motion knob turns almost a whole turn, in tightening and loosening, instead of the more common 120 degree range. The ball bearings give it a really smooth feel at the point of tightening. The ball bearings are each 0.187 inches in diameter.

Hopefully, this will help. I'm guessing that the 'White' assemblies that have ball bearings are the same. I'm sure John would be willing and better able to help if further info is needed.

Janey - Neat people never make the exciting discoveries I do.
