Damn! So this is a picture of my bike looking not well. I went to service my bottom bracket the other day after I noticed that it was a little loose.  It’s a three piece BB that I’ve rebuilt before so I really didn’t think anything of it. Everything was going well. I pulled the cranks, unscrewed the adjustment cup, pulled the bearings and spindle. I got everything cleaned up, repacked the bearings and started to put humpty dumpty back together again.

I noticed upon reassembly that the lock ring wouldn’t tighten down on the adjustment cup. I pulled the cup out and realized that it was cracked between two of the treads in the middle.  Shit!

It’s so damn frustrating when ya think everything is going fine and WAM, a cracked adjustment cup. So I’m gonna do what I should have done the first time I had trouble with this thing and get a cartridge BB. You live and learn.
