Anyone ever have one of these apart? Rather than the cantilevered motor rotor like on an oliver this has a rear motor bearing. Normally not great engineering practice to have 3 bearings in a row like this. Anyway, I need to remove the rotor so I can tap a small bit of blade out the motor end of the cutter head before I restore this machine. Cutterhead side end bell and motor side bearing housing are one piece, I can't find a picture of the motor rotor but it must be hollow I think. Anyone take one of these apart?
