I was looking for a tool as well, Ultimately I ended up making my own. I used a bolt that was 1/2" cut the head off and came in just from the end and machined it down to 12mm, on the threaded end I drilled a 3/16" hole almost all the way through the bolt, from the other end I drilled a 1/16" hole till it met up with the other, then I slit the bolt so I had 4 slits. then I took a 1/8" rod pointed one end and slipped it into the 3/16" holeand left a little extending out the bolt. I made a collar that would fit a old slide hammer and the bolt. So you push the bolt through the bearing till the little lip has passed through the bearing, then when you tighten the slide hammer, collar, bolt it pushes the rod down through the bolt causing the split end to expand, then I heated up the area around the bearing and used the slide hammer to remove the bearing. Worked like a charm.
