Campag Hub Rebuild-

I have a Zonda rear wheel that appears to need a rebuild. The bearing seats/cups press in. The manuals say that the correct tool should be used to remove them and a press to refit the new ones. Does anyone have experience of this job and do you really need the correct tools? I have rebuilt the freehub, replacing the bearing cartridges by bodging with sockets etc. The tools seem expensive and the LBS won't do the job, so I'd need to send it away if I didn't DIY it.The rebuild kit at £40 seems to be the only parts option.

    If not reusing then bearings then simply drifting them out is OK. Likewise, pressing new ones in using a soft mallet + socket on the outer periphery is accepted practise if you know what you're doing. You have to be a real bodger to damage the hub shell and replacement bearings are cheap.
    Make mine an Italian, with Campagnolo on the side..
  • The correct tools make romoval alot easier. The only way to drift out without the extractor is to use a screwdriver but you will only be able to tap on the inside of the cup and you may find it really hard to get the cups out that way.

    It is a bit fiddly but you can and as Monty says, a socket will suffice. I would in almost any event replace the cones at the same time even if they are even and smooth. Ribble are good for bits and bobs and peruse the Campagnolo Pdf files as they can give you serial numbers for parts. E.g RE-022:

    Keep assembly pristine so wait till the OH is out and do it in the kitchen! I have come across so many hubs that have been contaminated during assembly with terrible results and rapid deterioration.
    Take it apart. Clean up big time. Re-assemble and make sure the grease contains no contaminates.

    Probably a bit redundant and you may already have viewed this but here is the link anyway:-

    The bearing cup removal tool is probably the most difficult to replicate but I seem to remember another thread where they suggested bearing removal tools from other engineering spheres. For example a pilot bearing puller used in the automotive industry might do the job for around £20

    You may be able to find similar tools for less money

    The special bearing press used half way through is the expensive item that is not worth acquiring for a job that you unlikely to repeat for another couple of years. However if you can find a couple of sockets of the correct diameter then I'm sure you could mackle something together with some threaded rod and wing nuts or standard nuts
