If you are going to remove the flange, you need to go the entire route or risk problems.
My question is, can I just remove the nut at the center of the flange, and then spin and push on the shaft to check for smoothness and play of the IMSB and if removing the nut will allow me to check on the bearing, do I have to lock the cams if I am not disturbing the flange?
