I took the BB apart again. I measured the spindle diameter adjacent to the spacer and it measured 16.97mm!! The other side is 17mm on the nose. I presume that the spindle needs to be 17mm for a good solid press fit. THe bearing measures 17mm on the ID. It just slides in and out of spindle and has slight detectable play. I cant believe that I "wore out" my spindle. It has been 10 years.
Might be a good opportunity to "upgrade" to Ti spindle. I seems that universal has the best price on these BBs - $108 SS version and $170 for Ti. Any other cheap sources? Of course, square taper is "dying" so maybe just go with SS and go Ultratorque sometime down the road.
In the meantime, to get the bike back on the road, Im thinking of using loctite to "fill the gap" at the spindle. Any other temporary ideas until I get a new spindle?
