have you tried putting a long punch down through the top and tapping them out, might throw some penetrating oil on them first or just let the whole stem down into a bucket of oil to soak.

Diddo on the long punch. I had a similar problem getting bearing races out of my Husky. Use a moderately heavy, like a small 3lb, one handed sledge. Don't hit in the same place twice in a row. Keep moving the punch in a star pattern around the bearing.

You have to use a moderate hit. Hit too soft and you will just marr up the frame and bearing, but nothing will happen. Hit Too hard and the bearing will come out but you will marr up the frame and bearing.

Patience and Persevence.

Sounds like you want to remove the bottom race off the stem, right? Best thing I've seen is a hydro press tp push the stem down thru the botom clamp. This will pop it loose. Then flip it over and press the steerer stem back in to the right place.

Head bearing replacement goes easy with the right tools but is a pain without them. A pipe of the right size can be used to re-seat the new bottom bearing on the stem. The top and bottom races going into the frame can be done with a punch, but better done with a piece of bar stock turned to the right diameter.

I just did my first set, and wow what a difference the right tools make.
