Google is a good place to get a million different answers. I was hoping to cut through the BS and get suggestions from people who've already figured out the best answer. That's what forums are supposed to be for, after all.

God, $197 for a torque driver? That's insane. I could buy 10 big torque wrenches for that price -- they wouldn't do me any good, but I could buy them anyway. What makes the Sturtevant Richmont torque driver worth $197?

Wiha sold one back when Schumacher was in the states. It cost like $29.99 and went to like 25 in/lbs. Couldn't tell you more beyond that, sorry

Don't think I've ever seen anything published specifically for the flywheel nut, but I have seen in a chart Grade 8 Hex bolt torque spec for 1/4-28 thread is 14 NM.
