I loosened the set-screw and the larger friction screw came out easily. Looking into the opening, there is no evidence of dirt or corrosion. But, immediately to the rear of the collar is a ring about 3/8" wide that seems to be pushed against the collar. This ring looks as though it was intentionally fitted close to the collar ring using some tool which I do not have. I think the retaining ring is fitted too tightly and will not permit the collar to move.
