Thank you for the video. I have a SB 75 with both armature bearings seizing. Never pulled one apart before, so very unsure about how to do it. From your video I learned that the armature fan unscrews anticlockwise, and the pulley at the other end of the armature unscrews clockwise. I copied your actions to disassemble and remove the bearings
