head bearings

[(RIP) Tibs]

It does seem a really extraordinary bit of design doesn't it...
They must have realised how succesful it was at making life hell for amateur mechanics and then decided to take it up a level and invent canbus!

Is the bearing that close to the steering tube. Is there no lip at all/ Surely there must be some lip?

There is a lip, but it's impossible to reach it from the upside with a straight tool. I have removed some wit a slightly bend tire-iron but if they are really stuck the tire-iron will flex.
I don't see how the above mentioned modification will help, the problem is that the frame is narrow in the middle and long.

A puller is far better, I've bought the tool from Cycleworks but not tested it. I guess a slidehammer can work if you fabricate something that fits above the race.

Heat can help a lot, the race might be locktited.

Hello

I already solve my problem!!

I had to cut the race with the dremel and after I had to force the race out. I used a tyre plier from my land rover! (to use in 750x16 tyres and strong enough not to bent)
One of the ends of the plier is curved and after a bit of reshaping I manage to insert it in the small lip. So I remove the bottom race hitting from above and the top one hitting from below.
Aprox 3 hours work to remove to bearings!


thanks to all!

So if there is a lip of sorts then this tool should work. It's such a simple idea. You push it in from the opposit end and when it drops into the lip you hit it with a hammer and knock out the bearing. I made one out of a piece of steel tubing to use on push bikes years ago.

Before you fit the new bearings, file a couple on indents to expose the bearing edge in the future.

Yes, that tool might do the job.
