I'm suspecting the tool being used on this bottom bracket is like one of the old Var tools that clamped down on the cup and then the pressure of the tool allowed the cup to be turned. I see it as now wasted and should be replaced. but to remove what is left would require a Campy, Var or even the 36mm wrench clamped down with BK's kit. and some added leverage like a big pipe. The 4 foot pipe has always worked for me. Smiles, MH
