Bottom Bracket Bearing Aggravation
I got my bottom bracket tool tonight and happily removed the bottom bracket. No problem. But when I realized it may not be very easy to repack the bearings, my heart sank. I searched the web for the bottom bracket - RPM BB 7420, and found many places that would happily sell me a new one for $22 to $25 bucks, but found no help at trying to clean and repack. Actually, http://maintainthatride.blogspot.com/2008/06/con-tent-thyself-get-it-its-supposed-to.html shows me how to repack the sealed bearings, but these bearings look like they are pressed onto the spindle. Lacking the knowledge to remove the bearings from the spindle and the BB housing (and lacking a press to put them back on) it looks like I am stuck with buying a new bottom bracket. Bummer - I was hoping to repack them and go. Does anyone know how I can repack these? I don't want to put this in the landfill, but I don't know if I can recycle it. How easy it would be to repack loose bearings.
