A question on the results of adjusting the spool end play/centering on Abu conventionals with dual knobbies and part #23500 speed bushing on the inside of the left side plate. This would be the brass bushing with the collar about midpoint on itself. When fully inserted, this collar "rests" on the rim of the cavity inside the left end plate. For this discussion, let's presume the manufacturing tolerances inside the reel are ok, and that the customary and usual spool centering/adjustment has been done so that the spool is resting where we want it. With the spool in this position, does anyone know if it's appropriate for the speed bushing collar to be absolutely flush with the rim, or somewhat away from it?

Less resistance on the spool, and less pressure on the bearings, were the reasons for the question. Even with some side to side (back and forth) spool movement, appears there is no cushion to the left side bearing when the collar is resting firmly on rim, thus possibly relaying more resistance, albeit very little, and maybe not discernable. With the collar away from the rim, both left side pressure and resistance is somewhat cushioned by the point of the bearing resting on the flexible brass spacers inside the knobby. When you compare this to reels which have the collarless brass bushing coupled with the toothed plastic spacer, which exerts no pressure on the bearing, but exerts some pressure/resistance on the spool, makes me wonder if anybody has actually noticed any difference in spool performance with the collared bushing adjustments. Hope this makes sense.
