Bearings Size - Campag Hub

Anybody know the correct size of bearing on the drive side of a 9 speed campag hub? I've dismantled and found a strange mix of bearings. When I try 1/4 balls the hb stands proud of the f/w housing , when I use 3/16th the hub passes too far inside, and the seal binds with the housing (if you can visualise from my rantings !). I've tried so far without including the pawls and springs, but they should make no difference. I think.

Anyone?

Hello.

If you try on this link, it goes to a PDF doc on Campas website.

Atleast it has a number on the bearings, maby it can be of help. If not get back on this and i see what else i can do.

Thanks Humlebaek.
I found the site etc, but the detailed drawings do not include ball sizes (if you'll forgive the expression) - I'm unsure whether Imperial or Metric is appropriate. I could try the Derby site (for campag) tomorrow.

thanks for your help.

Campagnolo freehubs use 1/4 inch ball bearings on the non drive side (9 of them) and use 7/32 ball bearings on the drive side (10 of them) You should always keep an old ball to size it and count the number of balls when dis-assembling a hub.

many thanks for that. My local shop advised 1/4 on both sides ! But I shall ensure next time I do this I will follow your advice.
