I was putting the flywheel back on my yz426 when I snapped the threads off while tightening the flywheel nut. I was doing it by hand with a torque wrench, not an air ratchet. I did not have the flywheel holder, so I put the bike in gear and had my wife stand on the rear brake (this worked for taking the flywheel off). My torque wrench "clicked" at 40lbs, but when I reset it to the manual's recommended 48lbs the bolt snapped off before the wrench reached its set weight. Is there anything I can do, other than a complete tear-down and crankshaft replacement? Of course this happened three days before a hare scramble I had planned on racing. PS I am quite proud to be using my first ever post to TT to show off my immense mechanical knowledge and ability.
