I have a situation here that's kinda bugging me...
I have a (NOS) Italian, aluminum, road frameset that I can EASILY hand-thread my old Campy Nuovo Record bottom bracket cups into, BUT when I changed course and put in a (new) Phil Wood BB using their aluminum cups, they require a wrench to install.
This is a dry-fit run, so I'm not installing the cartridge just yet...
Anyway, I can readily hand turn the first few threads of these aluminum cups and see that I'm properly engaged and not cross-threading, with no problem, but it becomes significantly harder fairly soon, to where I require said wrench.
I proceeded and fully threaded the two cups (both sides are acting this same way) into the shell and then promptly backed them out to inspect all the related threads (both cups and shell) and they appear quite normal. No cross-threading nor flattening of any threads.
I reinserted the cups and now have them awaiting in the frame for eventual disassembly and reinstallation with the cartridge, once I get some feedback here...
BTW, If I had to guess what force was needed to run these cups into the shell, I'd say about 10ft lbs. I never had to force anything, but I did use a longish wrench to aid in turning the Phil installation tool.
So, my question is, is this an unusual situation and did I potentially damage or compromise the threads on either the cups or the shell, or am I simply fretting over nothing?
Are the Phil cup threads simply 'taller' and are as a result much more snug than the Campy was in the shell? What gives?!
Thanks.
