The interference fit...not torque.
I have a leaking thru stud and decided to try SI 1290. It is very explicit that the interference fit between the stud and for should be .000 to .0035, any less and there's no seal and any more you can crack the webbing driving in the stud.
With the P02 stud I bought I have .003 interference (bore is .5008 and stud is .5038)...this seems like a lot for a 1/2" bolt, but within the .0035 allowance.
It went in, but it took a lot more effort than I was expecting. It could be I wasn't driving it as hard as I thought because I'm hammering around the other cylinder and being careful not to hit anything else.
All the research I've found online says that studs in new cases, which I essentially have with an oversized stud, can take some elbow grease. I just want to make sure I not jacking something up.
Seeking input from the overhaul gurus...
