Campagnolo Hub Renewal Kit

CheGuedara

Just a very short post which might be handy for anyone rolling on Campagnolo wheelsets and hubs.

If you've gotten to the point where despite maintaining your wheels and changing the bearings etc that you now need to replace the hub races and are looking for the HB-RE100 hub renewal kit (bearings, seals and races) and are having difficulty sourcing the kit [both Campag 'Pro shops' in Ireland are unable to source them] then I can recommend jimwalker.co.uk. It came in very reasonable in comparison to other online sites where it seems invariably out of stock and gets to you in ~10 days.

Was a PITA to source but thankfully easy to fit - hope this saves someone having to scour the web for the kit

Don't need it now but might come in handy at some stage - thanks.

On a similar vein, bought some speedplay bearings from some dude on ebay who specialises in speedplay spares and accessories (ti screws, axles and bowties for the super weight weenies) and much cheaper than the official kit.

Can't remember his name but if anyone needs to know drop me a PM.

Thanks for this just wondering does this kit for for Zondas ? Mine are 5 yrs old and i've never serviced them but they still run smooth and true. Think a bit of TLC wouldn't go a miss though.

As it happens I was replacing the bearings on a zonda wheelset - would have been bought in 06/07 but the differences between that and the 05 version are minor.

A quick glance at the campag site says the part numbers that make up the kit certainly havent changed since 2005. In fact it looks like the only difference between wheels like the Zondas and the top end shamal ultras is ceramic bearings - the rest of the kit is identical. I'll be fitting the excactly same kit to my Eurus wheels when the time comes for it.

Dissassembling the front hub is quite easy -

wrote:

• Take the qr out and put aside
• Get two 5mm allen keys and use them to unscrew the axle end, again putting it to one side
• Use a 3mm allen key to open the adjustment collar, unscrew and set to one side
• Remove silver split washer and the bearing cone under it - do not lose this washer you will need it later. The bearing cone will be replaced
• You should be able to push the axle out by hand now. When you do it will come out with an outer cover and the other cone attached to it.
• Now just pull out the white seals and the bearings.
• You'll need a flat ended 'something' to tap out the original bearing races and while the new races go in pretty easy (greasing them and thoroughly cleaning the bare hub before hand) having a bearing press (or something that'll do the same job) to make sure they're properly set could be handy.

After that it's a really simple job of

• sitting the new bearings into place, whacking a bit of grease in on them while you're at it
• fitting your new white seals (a little finnicky but not bad),
• replacing the old cone on the axle (just slide it off the free end and the new one on,
• sliding the axle back through the hub,
• setting the remaining cone and split washer,
• screwing on the adjustment collar (just needs to be finger tight - over do it and your hubs won't spin well)
• replacing axle end
• Fit qr's, whack on the bike and ride

The rear wheel is a little different but not much so -

• Remove cassette and follow the instructions above as far as having removed the adjustment collar and removing the split washer.
• Now using a 17mm cone spanner and a 5mm allen key to remove the cassette body locking collar
• Remove the cassette body (should come away easily) - clean and degrease. When reassembling use only a light oil to prevent the pawls getting sticky.
• Now you can remove the axle and as with the front hub remove the old components, clean the bare hub and set in the new races, bearings and seals.
• Replace the old drive side bearing race and reassemble the hub sliding the non-drive side of the axle through the hub first and then fitting the non-drive side race, split washer and adjustment collar tightening up to take play out of the hub.
• Once you've the axle in place and the bearings tightened up fit your cleaned and lightly oiled up cassette body (a little fiddly with the pawls), screw on and tighten cassette lockring, fit cassette and qr, whack onto bike and ride.

The wheels could last as long as you do with maintenance just replacing the hub parts and rims as needed so long as it stays cost efficient.

If you're anywhere near Tralee and need the job done I'm happy to do hub servicing/upgrading (campag, shimano, mavic) for few beans.

Thanks very much for the info Che will have a go at this job sometime in the near future, your instructions will make it a lot easier.
