So I was torquing down my bolts for my flywheel on my black car and in the middle of it when I was damn near to full 74 ft lbs the bolt started getting easier and easier to turn. I'm pretty sure the threads are stripped, its still in there pretty good though, anybody got any advice?

Leave it in? And see if it'll stay or what?

There's no way I would leave it. Pull the bolt and inspect the damage. Its possible you broke the bolt, though not likely. At ABSOLUTE minimum loctite the hell out of that thing - I do not recommend it. Last thing you want is for that bolt to come completely loose!
What I do recommend is pulling the bolt and tapping the hole to the next size up. Maybe somebody else can chime in - I'm not sure if that would be enough to cause a balancing issue

Looks like the bolt almost broke off, here is some pics, It kinda looks like only a couple milimeters of threading are messed up actually inside the bolt hole though

Were you re-using the stock bolts? The stock bolts are torque to yield, 1 time use bolts.

Nah they were new stock bolts I bought from the dealership.
I tried ARP but they are too long for this twin disc clutch

X2...Chase them and you should be ok. The bolt looks like it failed before the hole did. the bolts should be softer than the crank.

Sorry but you are incorrect with your information.
The flywheel bolts are reusable they are not torque to yield, but new ones are cheap enough for good insurance and peace of mind.

I've had the torque wrench for 2 years and only used it like three times. Its a craftsman one, any idea where I can go to get it checked out?

They sell devices to check calibration but the easiest and cheapest way is to get another torque wrench and test it on bolt/nut... see if they both click at the same torque. Having a friend with a torque wrench would obviously be helpful.

Simple way to test.

Or take it back to Sears and exchange ?
