Tighten BB without removing crank?(7 posts)

Tighten BB without removing crank?Joe Nordic

I need to tighten my Veloce BB - the right side cup
is out about 1/4 inch. Can I do this without removing
the right crank? Looks possible with the right tool.

I am not aware of a tool that supports that. Park, Tacx, and Campy tools all require crank off. Plus you should have the right side really tight which means loosening the left side a bit, torquing down the right big-time and then re-tightening the left. Is this per chance an Italian BB? I just went through this problem a couple of weeks ago (posted here) and found that you have to use a surprising amount of torque on the right side to keep it put. (Campy says 50 ft.lbs). Teflon tape also helps.

Similar topic (kind of) - I need to remove my Italian BB for service. Before I start cranking away, to remove it, it's counter-clockwise on both right and left sides???

yes. Both cups threaded the same. Counter-clockwise removes

The Veloce cups use a series on external notches. These are 6 simple machined radius's. The fit of the Park Tool BBT-4 encloses all notches, so the arm must be pulled. Engaging less notches with full torque is likely to cause damage.

In anycase, both left and right side cups on Italian are right-hand threading.

You probably shouldn't be messing with bottom brackets.

You could probably come up with a way to do it with a special tool, but why? It's really a piece of cake (with the standard tools) and it takes more time to talk about it than it does to do it. If you don't have the tools, don't want to buy them and don't want to learn then drop the bike at the LBS.

BTW - having RHS cup out 1/4" is significant - you may have already trashed some threads.
