After I got it apart I could see that there was no way it was going to come off the way it should.The pin and the shaft had that much rust on it.I still have to clean a bit more rust of the shaft.So I guess it was the only way of getting it off.I was happy that the flywheel wasn't that good.Didn't have no problems in breaking it.I did when I had to do the same with a Model 2 Rotomo.That was very sad.A very good flywheel that one was.
