Fork tree bearing removal

What is the best and easiest way to remove the pressed on upper bearing off a fork tree. I tried my bearing speader but it doesn't get on it enough to pop it off and I am not about to beat on it with a hammer.

 

Get something comfortable to sit on for awhile.
Push some damp wads of Kleenex in your ears.
Gloves.
Load-up the Dremel Tool with a wafer-thin Cut-Off wheel and let the cutting through that sumbidge commence.
Have the TV remote, coffee, cigarettes, spare cut-off wheels and the little screwdriver all lined-up before getting cozy!

Bingo.
Good-bye.

 

I like the your train of thinking but now for the horrible news. I am trying to get it off in one piece. Kavey was attempting to ride his bike with no bearings in the head. I told him I would give him the set off this spare tree I had so he wouldn't kill himself.

 

You might be able to get a garage with a press to let you use it!?

Are you using a fairly large bearing seperator?

Then there is the possibility of freezing the shaft away from the bearing with some co2, you'll need a fairly large tank of C02 or you could go to the paintball shop where they fill tanks.
If you freeze the shaft a couple of inches away from the bearing sometimes the extreme cold will cause the shaft to shrink enough to release the bearing. You'll have to work real fast because the bearing will try to cool down and shrink too.
Have something to tap with and some good insulated gloves. and some prying type tools/things.

Maybe you can do it!!

Good Luck

The other trick is to "Nut-up" the threads on top. Protect them. Thread-on one big nut ... followed by a washer ... and then ANOTHER big nut and tighten the two nuts ... leaving JUST ENOUGH "Headroom" on the Top Nut for applying some IMPACT down that shaft.

The Upper Nut does take a beating ... that's it's role ... take the beating and protect the threads.

Someone needs to apply opposing force on the bearing when the spindle is struck. Sometimes you get very lucky and it only takes a few whacks.

Be sure to leave room so that the threads are NOT damaged.

 

Find yourself a friend with an air compressor and air hammer. Put a dull flat bit into the hammer, then regulate the pressure down to about 50 psi. Put the bit on the outer edge of the race and start the air hammer. Use as low a pressure as you can get away with, and move it around the periphery of the race to even out the force so as not to cock the bearing to one side. I used to do this to take bearings off of compressor cranks and it works very well, but you have to be careful if you want to save the bearings.

 

This is the bearing on the bottom of the tree set.The one on the opposite end of the threads. I managed to get it about 1/32" away from the fork clamps with the bearing speader but cant get it to budge any more. I can only access about a 3rd of the bearing face to remove.I have trie da wedge but can not get access to the other side. I can post a pic in my gallery if that will help anyone.

 

Got it. Used a tie rod end tuning fork to get a little distance from the brace and then used it as a chisel to hammer it down the shaft. The seal didn't make it but the bearing came off in good condition. Thanks for all the input.
