heat and wd40 do wonders.

or a bearing splitter and a hydraulic press.

Take the forks out, put the stem upside down in a vice. You should be able to get a punch onto the inside race of the bearing at the rear side of the triple clamp (you might have to go through the dust seal). Give it a good hit and it will drift off the stem.

just use a hydraulic press. they can be had for cheap from harbor freight. I wouldnt put a harbor freight on in a pro machine shop but they're fine for home. Put the lower triple on something that allows the stem to not be covered, then press the stem down from the top. POP! bearing pops right off. You can then press the stem back in from the bottom, or now you can get creative with fitting new forks to your bike.

Sorry but this idea doesnt work on that bearing. Its been on there for ten years and i gave it a million good hits cause i had this idea to but it didnt work...all i got out of it was a sore arm.

press the stem out with any basic press, or even a vice. You can get presses all over the place. Usually looks like a bottle jack for a car and a crossbeam with a table that's adjustable using pegs.

Pounding on it, heating it, etc. will just marr it and fuck it up.

The only good way is constant increase of pressure.... a press. :thumbup:

I've cut plenty of bearings off without fucking up what they were on. I use oxy/acy to cut them

It's definitely possible. I've blasted some bolts out of threaded holes that were rusted in using an oxy/acetylene cutting rig with some luck and a LOT of patience. ;)

You just need to have a steady hand.

With this though it's pretty easy to just pop the stem out (removing the bearing at the same time) and then repressing the stem.

Two ways to skin the proverbial cat so to speak. :rock:

Yea... I didnt get to take a stab at it today but tomorrow im gonna try and get it off with a dremel. First im gonna put some heat to it with a propane torch and then try to knock it off. But if that wont work im just gonna get out the dremel.
