I don't usually remove the fixed cup during an overhaul, but I do always check if it's secure. This Sugino cup, from a '72 Torpado, came loose fairly easily with an adjustable wrench. So I removed it for cleaning. Now, how to secure it? What's your method? Just a little bit of grease? An ample supply of blue Loctite? Some combo? (Does that even make sense?) I can't remember the last time I did this for an Italian...
And, yeah, it has Sugino cups and crankset and a Campy spindle.
