campagnolo freehub bearing change

[molou...@gmail.com]

wondering if anyone has done a bearing change in a Campagnolo Freehub, the outer bearing is easy to get at but the inner one is behind a snapping/circlip.

Do you need this retainer? I have got it out, but it isn't reusable...

Thanks Martin

Yes, I think you could probably run without it, but frankly
that snap ring is not as difficult as other aspects can be.

Next time, get the right tool first. Saves time money and
anguish.

I replaced it once with a slightly modified internal circlip.
The time I spent and the money I spent on the bearings made me decide not doing it again. Next time I buy a new freewheel body including the bearings.

Can you tell us what the right tool is to remove the retaining clip without damaging it Andrew?

BE aware if you do go the replace route that there are 3? patterns for Campagnolo Freehub bodies. Two are based on the c17mm aluminium axle and one for the steel c10mm axle.

IT seems that the older large diameter freehub is discontinued and the almost identical new version will not fit as the axle has been tweaked. If your hub is 2000-2007 Daytona/Centaur/Chorus/Record it needs the discontinued body, if it is the new record hub your ok for spares.

I have been told that the new axle will fit in the old hubs so if you want to change the freehub body you also need to change the axle!

As i don't really want to change the axle and the freehub body, thought i would ask if anyone knew if you needed the clip.

As for the correct tool. There isn't one, the freehub is sold as non-servicable by Campagnolo, which is fine until they no longer make spares!

Micro snap ring pliers. Squeeze to open the shaped end out
from the body, lift the edge out of the groove. This can be
done with a jeweler sized 2mm screwdriver less elegantly but
still without damage.

Lock ring pliers. Heh! It rhymes with... Err...

Of course having the right tool for the job does not mean it will be easy
there is a reason the British refer to spring lock rings etc as "ping
fuckits!"

your assuming the circlip has holes for the pliers to fit into.

For reasons known to Campag, there aren't any.

It just has an angled relief at the end.

When you look at it you only see parallel ends 0.5 mm apart.

Yes I can twist one end out of the grove with a small screwdriver. Then
I needed a second screwdriver to massage the rest out of the groove in a
very limited space with no sight on what you are doing. I asked my
mechanic at the LBS how he does it. He answered: with a lot of patience
and some cursing when no one is in the shop. I really would like to see
a picture of the pliers you use.

After consulting with my employee, the current aluminum
bodies indeed have parallel flush ends on the snap ring. I
can see where that would be difficult! I've only ever
replaced those for cracked body. The older Campagnolo steel
bodies have a 45-degree angled end to the snap ring. I
change quite a few bearings in those (without much trouble)
because no one else here will do them.

[Lou Holtman]

Ah, I thought I missed something. I just remembered that out of frustration
I drilled a small 2 mm hole in the aluminum body at the lockring position
so I could push the lockring inwards from the outside. The lockring gets
damaged when you pull it out. These bearings are to not meant to be
replaced. I paid 20 euro's for the replacement bearings and a frustrating
amount of time. Next time I buy a new body including the bearings. Only 40
euro's more.

read my earlier comment, check which freehub you need because some can not be replaced as no longer made.

I wonder why that might be.

(And yeah - spring circlips are wicked.)

There are no rings in the shimano circlip holding the cog on to the IGH
it's a ring of spring steel. You just have to carefully spread it with a
small screwdriver enough to get the ring pliers in then they enable you
to spread it enough to get it off. There are many different shapes of
pliers you just need to get one that is useful for the task at hand.

Lock rings are not an easy task even with the pliers though. Good luck. ;)

You know we are talking about a aluminum Campy freehub body yes? If so
your explanation doesn't make sense to me. It is an internal clip. You
don't spread them to get them out. You have to pry it out of the groove
in a 40 mm or so deep hole with a diameter of about 30 mm Mr Muzi got
it right in his second post and admitted he only replaced a bearing in
the old style Campy freehub body.

I have a power steering pump that is disassembled like that. The hole
is already in the body of the pump though.
