I have every thing off the front of the naa, but I can't remember how to get the flange on the end of crank off (the flange that the belt pulley bolts to), I can't tell if it's pressed on or if there is a threaded nut of some kind that holds it on, there is something there that looks like a big star washer or could it be the splined end of the crank? I don't see any sholders like a nut but there is a grove in the end of the crank almost like a grove for a very large screw driver. I put my large gear puller on it and put a tremendous amount of tourque on it and it didn't move, so I stopped before I broke something. I remember there was something odd about this when I rebuilt the engine but that was 13 years ago and for the life of I can't figure out what it was. Ron and Mary will be doing this in the spring also so any advice will help them also. Thanks and God Bless, B&A.
