Interesting! Both my spacer rings are 40 mm od.

Your last drawings are much different from what I have.

Yes, interesting, I don't have the small ring at all. I wonder if others have the small ring spacer?

Mike -

[Edit] I'm not positive there is an inner ring and an outer ring that make up the spacer as shown on my sketch, but there is a definite shoulder (ridge) on both sides. After seeing yours with no shoulder, maybe mine is only there due to wear, bearing spinning in the eccentric.
