Everywhere I Iook says 58%. Also confusing is that the NOC says all are the same and lists the same individual part numbers for all pre-MK3 but that disagrees with the parts books, AN, and RGM. According to the NOC article, I can use it - found that after I asked here. Then, AN still lists the bolts but provides only studs in the kit that they say is good for 72-74; prior to that they list a kit with bolts. So, information on this is all over the place!
Thanks! I must be blind! I have a searchable database of the serivce releases on my web site, searched for crankshaft, and didn't see if before starting this thread. I see it now! I also see typos I need to fix in it.

Not that it matters to the mass inside the cases but isn't there a change to the crank output stub to accommodate the electric start mechanism? And a minor change from three fixings inner primary to the cases versus four on the E/S?750 vs 850 Commando Crankshaft
Does anyone know the difference between the 1971 - 1972 750 & 1973-1974 850 Crankshafts ? Can the 750 crankshaft be used in 1973 850 cases without problem ? Another question is, Why does the 1972 Combat engine have the extra Tabbed Thrust Washer on the Camshaft ? Thanks in anticipation...
