Greasing My Campy Hubs

Also, what about the bearing way out on the right, under the cassette?

What do the shop pros do?

There is a pdf file on the Campagnolo site that explains how to get the hub apart. It's very easy to
do and requires minimum tools. I use a fine piece of wire to hold the pawls together when
reassembling. It sounds harder than it is. Replace the balls and add grease. You don't grease the
front or rear by shooting grease into the hole in the center of the hub. That port is for show.

[going slightly OT here] When I pry the dustcaps out of the hubs, I usually end up distorting them a
bit, so I have to bash them around on the workbench to get them straight again. Is there a special
tool made, to get the caps out in a nice even fashion without bending them? Mine always have that
nice destroyed look but as long as they keep the crud out I don't mind all that much. But I'd like
to find a better way ... /Robert

mn robinson-<< No problem on the front hub. On the rear, grease comes out the left bearing, but
oozes into the freehub mechanism on the right. I have opened this up and cleaned it out, but getting
all the pawls & springs back in is tough. Can I leave the grease in the freehub? >><BR><BR>

1999 Record hubs have pawls held in place by a spring, much easier than older hubs. If you have
pawls that fly around, the hub isn't a 1999 model. Ya can leave grease on the pawls but too much and
they can stick down. Injecting grease into hubs should be viewed as an interim measure only and
should not be used as a substitute for a complete overhaul.

There is a little 2mm set screw in the freehub body, remove that to inject but the best is to
overhaul the hub, take apart completely, including freehub off, tapping out the top bearing,
cleaning and regreasing the two cart bearings in the freehub, removing the 5/32 balls, cleaning all
well, replacing balls and adding new grease.

I have '99 record hubs on by bike. When I service the hubs, I just inject grease into the port
until the old grease comes out through the bearing dust caps. No problem on the front hub. On the
rear, grease comes out the left bearing, but oozes into the freehub mechanism on the right. I have
opened this up and cleaned it out, but getting all the pawls & springs back in is tough. Can I
leave the grease in the freehub?

We just disassemble completely. We get a very thorough cleaning that way.

If you remove the sprockets you'll find a grease/oil port on the outside of the cassette body
between the two bearings.

If you plan on using that, you might leave out the inner seals of those two bearings as I think it's
going to be hard to get grease past the seal. And I'm not so hot on grease injection through the
pawls. You're risking a surprise some chilly morning.

Older campy freehubs come with a metal clip that holds the parts in place during removal and
assembly. Newer ones come with a plastic tool that works better for assembly but doesn't seem
useable in the other direction.

That doesn't work well.
