Campagnolo Freehub O Ring

[Halla]

Hello All.

Just discovered that the O ring at the back of the free hub is broken, also the pawl springs are bent. The hub is 1998/1999 - 9 speed Veloce, I cannot find a model number for the hub or freehub

I think that the O ring part number might be FH RE012.

The bike has covered about 10000 miles in it's 20 year life.

I have found Campagnolo spares on the Mercian website, are they the only suppliers in the UK?

Should I just obtain and change the O Ring and Pawl Springs, or should I cover myself by doing more work to prevent further problems.

Also what is the best grease to use when replacing the parts.

Many thanks for your help.

I am still using a 97 Veloce rear hub. The O ring has become oversize but is still in one piece. I have not replaced the springs as they were not bent. I did have to replace both internal sealed bearings in the freehub and both axle cones (and balls of course). Re lubrication I'm currently using a Castrol EP grease available from RS. https://uk.rs-online.com/web/p/greases/1983186/

p.s. you'll need a special clip or bent coat hanger to keep the pawls compressed while you re-assemble. I find it very fiddly. Beware of everything flying across the room. Good luck.

This one?

Mercian is my first port of call.

Grease?
Clean the bearings out regularly and use a good quality normal grease. Do it lots, and do it frequently.
You need the knack with those silly pawls and springs. The Chorus and Record versions are easy peasy.
