I'm rebuilding an old OS32F-H for my Kalt Baron and the rear bearing is rusted and locked in the crank case. Does anybody have a good method to remove it without damage the crank case?
I already used the traditional heat method and it worked for the front bearing but the rear one is really refusing to get out.

Thank you!!

Marco

350 degrees in a toaster oven for 12 minutes works for me. Add salt if you like.

To hover is divine, the alternative is rather PLANE.

I used 350 and left the engine in the oven for about 15 minutes.
Thank you for the replys.

I did it!! I was able to squeeze some thin washers behind the bearing race and press it out after heating the crank case!!
