I have a question regarding Campy hubs. I just got a pair of wheels with
Daytona hubs for winter training and I would like to service the hubs before
I put them on the road. How do I disassemble the hubs to get into the
bearings? I tried putting a 5mm hex wrench on both ends of the skewer hole,
but I broke one of the 5 mm hex keys and I couldn't turn it loose. How do I
Happy Holidays, Robert. I've attached 2 files from Campagnolo's website tech
pages http://www.campagnolo.com/techinfo.php?did=f that should get you
going. One is a pdf doc showing an exploded view of the 2001 Daytona hubs.
The other one is the instructions for working on 2007 Record hubs. I haven't
worked on the Daytona hubs but from comparing the diagrams I believe these
instructions should explain the steps to take those hubs apart because
they're similar in design, not identical but similar enough, I think. It
looks like you were right to use 2 5mm Allen wrenches. Since one broke maybe
the parts have gotten a little frozen. Try again but use Allens that are
higher quality and have longer handles to give you more leverage. The
directions don't say to do this until the next step but maybe try loosening
the screw in the lockring first, too. Maybe that will help.
I'm assuming you have Adobe Reader installed on our computer to read these
but most people do. Or you can download it for free.
I hope this helps,
