His bearings already fell out, he was/is just removing the outer ring. Joes engine was also brand new so everything was nice and fresh, that counts for something, I think?? I had an old OS 1.20 I was rebuilding this year and the bearing was so fused into the case that when it did finally come out A part of the case was fused onto the bearing itself. I just happened to have another case but it was the first time I have ever seen anything like that in A model engine. The engine had years and years of hard use and had never been rebuilt before. I bought it used and know the fellow I got it from thought removing the price tag from the prop was ballancing it. Not sure if that would have hammered the bearing in or not but it was sure pounded in??
