Is the book correct on this 101-115 ft/lbs on the left hand flywheel nut the reason i ask is cause cam sprocket shattered while trying to get it there and was only at 60+ ft/lbs when it shattered......i just got my 3rd sprocket and want to get back riding soon so please help lol am i missing something? ive checked and rechecked all gear and cam chain alignments im stumped

by the size of the nut, the torque spec is about right(actually very conservative)...  are you sure your torque wrench isnt in need of calibration?  got your hardware stacked correctly on the shaft? any burrs or such on splines? a 1 ton compressive load shouldnt even phase a steel gear that's mounted correctly....

can you post a decent pic of the remains? preferably both sides, and edge shots of the break?  about the only reasonable explanation (assuming all parts were installed correctly) is the gear was defective... if the steel was burnt during the tempering process,or if it was hardened but never drawn(glass hard thoughout), it could conceivably shatter under torquing.... if the shaft hole was improperly machined, torquing could split or crack the gear....  i guess if you immobilized the shaft by using one of the gear teeth to lock it, you could maybe have gotten it to "cant" on the shaft while torquing....
