Replace bearings on Roval front hub?

02gf74 · Aug 20, 2011

as title, any done or know how to do this?

looks to be the sealed bearings are pressed into the hub, and the inner race sits on a metal tube.

I am guessing that if the tube can be pressed out, then the bearings can be pulled or tapped out from the other side.

had a similar thing myself, so this old thread might be of some use

done it; ... now will take a look at your fred.

.... actually not that hard. using a length of 8 mm studding, different diameter washers, a socket I made a puller to pull out the central tube and bearing, and then the other bearing.

bearings are on order (from simply bearings) but does anyone know where I can get 6704 ceramic bearings?

photo shows the different bits and pieces used.

worth a try?

I can pick up if they won't post as very local to me.

thanks for the offer - I have bearings on order, will probably get them mid week.

I wish I could justify spending £ 120 for a pair of these:
6704 Ceramic Bearing
5.5 g
