im pretty sure he understood that the cases had to be split. personally i wouldnt press a crank bearing out with the cases cold. have seen them crack in the past. if you heat the cases up either to take it out or to put it in, is alot safer. also i would put some 640 locktite around the left crank bearing( stator side). after time they will spin in the cases. if you do use the 640, you want to put a thing line. then wipe it about off. if you put too much, it will barely turn. makes it a really tight fit,and wont let the bearing spin in the case over time.
