Hammer & punch

Did mine last week, a feker of job without a vice, and nobody to help hold the yoke while you hit it Eventually got the bottom race off using a hammer and cold chisel (not too sharp) between the ally of the bottom yoke and the base of the race to get it started, then as Knackered said, a hammer and punch to finish the job. Just take your time and work around the stem, gradually, if that makes sense

Dremel or some heat applied quickly just to bearing [interference fit ] then sharp crack with chisel and twatting mer.

i realy cant get it off
bearing has just feel apart iner part left stuck right on
will get some heat on it tommorow maybe
can i remove yoke from axle if so how put in vice and twist it off ?
then i could put some round bar over and plonker the bearing one!!

[Jonorow]

do as mike says, use a dremel or similar. it's the best way i know of. and if you do it right you can keep the old race to use as a drift ( with suitable tube) to drive the new bearing home.

Now that the bearing is broken away, try getting a small sharp cold chisel and with the yoke on a hard surface and the center tube facing up ( as on the bike) strike a cut into the top of the bearing ring, and it should break in two as it is so hard it's brittle, if you have a dremmel try grinding a starter cut first.

Nabz..dont try to part the stem from the bottom yoke!! That lot was assembled by Mr Hondas finest, with the idea that it didnt come apart again!
Sorry mate, but it MUST be easier to drift whats left of the bearing up the stem, in the fashion advised by the other replies.

Well for the case in question the bit your left trying to drift off is the inner portion of the race.
The bit that's already fallen /been hammered off is the outer race.
The bit that was in between the rollers are sometimes round and sometimes cylindrical .

ball bearings round.
cup bearings cylindrical

taper bearings angled race.These are the adjustable type used in most car hubs and steering heads .

ah i would have called em bearing tracks
cheers m8

nick if you still struggle to shift the race,try an angle grinder and gently remove material from the inner race,being very carefull not to go through the race and damage the stem.i've done this twice now on very problematic ones and both times the heat generated by the grinding combined with the removal of material loosens the inner race.
this is a last resort and taking your time is vital so damage to the stem isn't caused

ok so..when i get it off and put new one on is there a good method so it comes off easy next time?

[NaBz]

yay i got it off!!!!
put it in vice and gave it a right plonker came strait off near enough
just needed the vice yaaaaaaaay!
rear caliper piston was just another story tho man !!!
was seized like shite!
in the end after lots of wd40 i plastic peice of pipe a wood screw and a air tool + blow tourch
