Exploded view for Campagnolo Record 10 Freehub body, 2009 or so

I'm trying to help a friend replace the bearings in a 2009 or so Record 10 speed freehub body. The inside sealed bearing completely self destructed and I'm having trouble seeing what's left and where it seats.

So far I've pulled the outer bearing, the spacer, and a spring steel retainer out of the body. I'm assuming the outer portion of the destroyed bearing is still in place but it's hard to see a spot to knock it out, and I do not want to be hammering on the body if it is not in there.

I'd really like to see an exploded view to see what is supposed to be in there and how it all lines up. It was already disassembled once before I saw it so I'm not sure how much shrapnel was gone already, and that's why I'm not sure if there's anything left of the bearing.

I'm assuming it's comprised of a sealed bearing seated all the way in, then the spring steel retainer, then the spacer, then the outer bearing, but?? Anybody have experience with this job that could help out?

Exploded diagrams are usually available on Campagnolo's web site as PDF's under the spare parts listings:

Exploded drawings will be of no help, because Campy considers the cassette body to be nonrepairable. There are two identical bearings at the end and the retaining clip, as you've found. If you can't see the edge of an outer race to knock out the inner bearing, I think you're out of luck. Normally, you'd remove the circlip and knock the inner bearing out, by applying force to the inner race.

Yes, I finally checked it with a magnet and could locate what was leftover race, and was able to knock it out. And it looks like two identical sealed bearings, which hopefully I can buy at the the local bearing house.

It is pretty obvious that they did not intend for this to be "serviceable", but I think it will work out. Worth a try at least, it's only time, and hopefully some cheap bearings........

Yo are correct. Campagnolo sells the freehub body and bearings as one part. I have not done it, but others have successfully replaced them for a few dollars at their local supplier.

Could you do me (us) a favor by reporting back with bearing numbers?

The inner bearing's not a super-tight fit. You got the hardest part done, removing that darn retaining clip. I've resorted to drilling a hole through the wall of the freehub body to push the clip out of its groove a couple times now.

Tip: if you need something to press on the outer edge of the new bearing without exerting force on the inner race, take the outer shell of the old bearing and slice a slot in it with a hacksaw or Dremel. It's the perfect size to press on a bearing of its type, yet it won't press-fit since you've slotted it.

Yeah, that clip was not designed to come out. There was a little notch on one end and I was able to pry it out of the slot enough to push it down with a screwdriver. Drilling a hole through is a good idea though!

Found a cheap-o socket that is the perfect size to drive in the bearings and cut a square face on it in the lathe so that's covered. Just hope the bearings aere easy to find tomorrow.

I'll post the numbers when I get them.
