163cc case half bearing race removal

I am freshening up 163cc rotax. I need to remove the inner race's from the case half's but they are being stubborn. Tried by the book heat the case and tap case half on a wood block, but to no avail. Any input on this? I have removed this type of bearing years ago but can't remember how I did it. It did not seem this difficult. Thanks, Rick

If you have a welder run a bead around the inside of the bearing race. As it cools it will shrink and should just fall out.

I forgot to state that I was saving the race. I got it to pop out. Was not getting it hot enough!
