I have the service manual and I’m going to be attempting my first right crank seal replacement and also figured I’d rebuild the water pump while I’m in there. I’ve been searching the site for posts with tips and was wondering if I have to remove the impeller nut before I can get the clutch cover off or is the impeller shaft not locked onto anything behind the cover besides mating with the CB? I’m asking because I don’t have a impeller holder and don’t want to break it trying to wedge something in to hold it. I read once it’s out I can use a flat blade to hold the shaft from turning while torquing the nut down. Will I need to remove the clutch basket to get to the crank seal? I didn’t order a new locking tab washer for behind the main basket nut.
