Steering stem bearing race removal

Sorry

If I could press it out I could treat any corrosion that's been working away for 35 years, especially between the dissimilar metals.

There should be room for a small bearing clamp remover? Then press or pull the bearing off using puller with threaded rods all the bearing clamps have two threaded holes.

I used to grind the cup race off with a power file or a dremel but now just take it to a bike shop and ask them to press out the stem and fit a new bearing. Way easier and no risk of damage. My 6 tonne press won't budge the stem from the lower triple clamp.

Press and heat. I call heat my 2,000 degree liquid wrench. From my years of heating things only half the diameter needs to be heated.

My point is by heating the whole diameter we put too much heat that will transfer into the shaft. Heat half the diameter will expand half the diameter more and release the bearing.
