I have an early Campy freehub wheelset that I got off eBay a few years ago. I haven't used them much, but I finally decided to repack the bearings. I started on the rear, with no real problem disassembling the hub. However, as I got around to reassembling the hub, I noticed that I have 19 balls, nine 1/4" balls and ten 7/32" balls. Of course, I didn't notice the difference in size when I took the hub apart. The cones and races all appear to be in good shape. I thought that all Campy hubs used 1/4" balls. Anyone have any idea what's going on?

Here is a link to Campy's spare parts cat. (Part B) from '94. If you scroll down to the hubs, you will see exactly what you're describing.

"early" is rather imprecise.. 70's Freewheel Campagnolo hubs were 1/4" ball filled races, as the PDF shows the later freehubs are not,

I expect, the driver itself has another set of bearings ..

Thank you! I couldn't find that anywhere on the internet but here!
