Let me first state, this was the perfect way to end a shitty day. So I get my block back from machine shop, fresh hone. I go to install the ARP Studs, torque 2 down. Third one, just stopped spinning, the force behind the wrench and the little allen hole got stripped. But it gets better. It stopped because the stud stopped turning. It seems to be over torqued from a piece of **** harbor freight torque wrench. Ok to my question... Can a machine shop get this bolt out, and re thread the hole in the block to accept another stud ? One with a larger bottom diameter due to retapping ?

 

i dont know if im right or wrong but u could allways fix it with a timesert they are not cheap at all.

an im sure an good machine shop could get it out

 

Are you trying to torque the studs into the block?? Or are you sayings that its stripping when you are tightening the nut with the head on?

 

Trying to torque the studs in the block. When the allen key stripped, it was because the stud just gave out and it felt like the bottom of the stud just got stripped out in the block. Since the allen is stripped, I can't do anything with the stud to get it out. And Fist, its so hard to explain fully what happened, but that seems like a wise answer. Either way I know its going to cost money, so I'm off to the machine shop in a bit to find out. Thanks

 

Well, since the stud head allen is stripped you can say the stud is trashed. I'd suggest drilling the stud and using an easy out to extract that bitch. Or I'm sure a pair of vise grips will grip enough to turn it out by hand. Just be careful of the block and you should be good.

Why in the world would you use a HF torque wrench? You'd get a better feeling by hand. lol

 

The arp studs are suppose to go in by hand and should never be torqued into the block. If the threads are clean and lightly oiled then you should be able to install all of the studs hand tight into the block with ease.

 

the studs are supposed to be hand tightened, for the record.

the stud is stripped out in the block too? yikes.

 

I had to torque my AEBS studs in the block.... It's something low.... I want to say 10ft\lbs

Then once the head is on I torque nuts to 35ft\lbs.... THEN to 70ft\lbs

It's important that you preload the studs otherwise they don't all work the same and or correctly.

 

Ditto. When you get your block back from the machine shop, you should check the main all of your threads and clean them out before installing them. Possibly blow them out with air and check to make sure there is no debris in there. Finger tight on the arp studs, You should feel them bottom out in the block, not tighten them down till they bottom out and strip the allen head out.

 

You should read the ARP instructions manual next time.

 

can arp headstuds go in either way i.e upside down?

 

no they can't. one way and one way only
