Steering head bearings, the PO and alot of curses...

Hi Guys,

I have had my Berg since November. It is a 2003 400FE and has no more than 70 hours on the clocks...well thats the good bit. The engine in fine the electrics are repaired and every thing was good until...yesterday....
The headbearings were very tight so I got replacements. Knowing the history of the bike though I was apprehensive and rightly so.
Previously I had to get the axels unstuck as the PO was a right pillock and hadnt even greased them. His only interest was the butt plastics he put on.
So I undid the yoke, took out the forks and lower yoke and started at the bearing races. :evil: The effing things were having none of it. Took me 3 freaking hours of heating, cooling and wacking gently to get them both out. Right arm is the size of Arnold's right now and not because of lonelyness. So when I finally got the new races in I was left with the lower bearing. Well I go through the service manuals I have and all, no mention on getting the bearing off.
On ktm you press out the stem but on the bergs I have no clue. Through various other sites I finally find out that I can remove the steering axel from the clamp by removing the circlip. Slim chance. The clip broke, and the axle is stuck. Tried tapping the bearing off and the ridges of the inner race broke off. Tried hammering the axle and this is no good as the stainless steel used is cheese like in strength.

Now I am stuck... the axel won't come out, the bearing wont come off, and I dont want to spend £xxx on a new lower yoke and axle. anybody have any ideas?

Sorry about the long winded post but I am venting frustration.

:( :(
 
The bottom steering stem is not really designed to be removed to remove the bottom steering bearing.The circlip is used in the assembly process simply as a stop when press fitting the stem in the bottom yoke.
While it is benifical to heat in oil the bottom bearing to fit over the stem during the assembly process,heating the bottom race to fit in the frame is counterproductive.Also heating the bottom bearing to remove it from the stem has the effect of tightening its grip on the stem.A hammer and drift cold usually does the job.If it does not move a grinder works to remove the race.
You are now in a hard spot I am afraid,to remove the stem you will need to try a very hot oven to gain enough expansion in the alloy,a flame could easily take the temper from the bottom tree and render it unsafe.You will need a press as well to both remove and replace the stem,a new circlip should not be a problem..
Good luck.
 
To get the races to sit in the frame I had to stick them in the freezer and heat the frame with a heat gun. Replacing the circlip is not a problem but getting the lower bearing off is. If you heat the bearing localy, you will get it to expand just a tad. This owuld work nicely if the effing thing wasnt stuck. Guess I have to find an angle grinder. The metal of the bearing is really tough. Tried drilling it, tried milling it..nothing.
 
When I have done mine in the past I had my local shop do it. The mechanic used a press to push the stem out of the lower yoke to remove the lower bearing, and then used the press tor replace the stem, and then to press the lower bearing on the stem.
 
Pressed the stem out in the end. Had to apply some local heat to the yoke to get it to budge all sorted now.
