 So, I was putting this all together, feeling pretty good as it was going smoothly. Was torquing the head bolts (i think that is what they're called) to 18 foot pounds (216 inch pounds) as was suggested in a previous thread - and snap. see picture. So I don't know if I just don't know how to use a torque wrench or if the torque wrench is broken . . . i'll confirm that with someone . . but in the mean time, anyone know how i get the stub out and replace? thanks!

I had that happen when torquing the head bolt to 15ft lbs a few years ago. Not sure if it was my fault, the wrench, or the bolt. I had much more bolt to work with after it snapped, and painfully used 2 wrenches at once until it finally came loose. Unfortunately, you don't have the luxury of that much length of the bolt left to work with. I would think, that if done properly, that a screw extractor would have to be ONE of your options.

It looks like there is still enough left to cut a slot in it and use a screw driver or old school impact driver with a flat screw driver blade...

it should come out easily with a pair locking vise grips. finding a new part might be more challenging.

This is why I spend $15 extra for new ones. They probably stretched when originally assembled and they couldn't take the retorque. Also what are you using for a TQ wrench?
I would try to grab it with vice grips, should come out fairly easy, if not heat around it a little with a torch and try again.

Tried vice grips, no go - the bit sticking out is connical in shape, so they slip off.
Tonight i'll try cutting a slit with my dremmel and then using a screwdriver - if that doesn't work, does one heat the case with just a propane torch?
also, thanks Devo for the website, i'll see if i can find em.
if these bolts are really too crappy to torque accuratly, should i just tighten them "nice and tight"?

When you torque them you can actually feel them start to twist,,you need to stop there...no twisting allowed  |

Yes, a propane torch should be enough. If you have access to a welder you can weld a nut to the stud then just wrench it out.

I can tell you when I pulled mine, three came out easy and one needed two pair of vice grips to get to get our. Double nutting didn't didn't budge it, and one would just slip so they can be in there. You could look at a bolt extractor for stripped bolts.

The one that snapped on me was pretty tough to get out. It wasn't to where it busted loose to where you could just turn it out easily afterwards. It was twist twist and twist most of the way.
