Does anyone know the spec? The wiki says 89in/lbs but the bolt I tried that on snapped right off; never even got close. Yes, I’m using new bolts (well I’m using all new except that one now).

7-8 foot pounds will work fine on a 6mm thread bolt

7-8 ft/lbs is 84-96in/lbs. Maybe for steel fasteners, but these are aluminum. And I tried 89 in/lbs already, that’s what snapped it off.

Maybe you had a dud

It is 10 N-m or 89 in-Lbs. Maybe try chasing the threads with a tap.

Did you use 89 ft/lbs?????? 89 in/lbs is finger tight.

Nope. 89in/lb is what I did with my 1/4” click wrench. That will snap them every time. The fasteners are torque to yield, because they’re aluminum. Here’s what I found:

That’s for an 8HP70, like in the 392s, not the 8HP90 in the Hellcat

Oops, you're right. Manual says for 8HP90:

Who can update the wiki on this? Because that’s where I got 89 from.

I know this is an old thread, but always good to replace any torque to yield bolts with steel bolts if you can. Torque to yield are single use only. This way you don’t have to worry about breaking them, and you can reuse steel bolts so you don’t have to get new ones if you have to get back in there.
