Make sure you get grade 8 and not grade 5. It would be a pisser to break the bolt while attempting.

The key about this is that since I was working on the adjustable side not the fixed side, I had to loosen the cup in the normal counter clockwise fashion. Normally if you fix a bolt to the cup and try to remove it from outside the frame, you won't get anywhere because the tool will loosen before the cup loosens. So I put my socket and extension INSIDE the bb shell and then I used the breaker bar to tighten the bolt down which caused the adjustable cup to break free in the proper motion. Use logic and reason to understand that the tool is going to work best if it is tightening down the bolt and nut and washers in the direction that you want to remove the cup since as you tighten the tool more, its trying to loosen the cup at the same time.
