Boy did I mess up today. I cleaned all the studs like directions said. Then used the ARP moly lube and torqued six studs into my spare motor with a head and gasket in place. I wasn't concerned about cracking an already cracked head. I torqued them up and down 6 times to stretch and set the stud material just like the directions state... But things gaulded. I have no idea why. What I did find was my sockets are not deep enough to clear the top threads on the stud. I rolled the threads on several studs but thats an easy fix with a belt sander too. I just don't know why the nuts grabbed the clean lubed threads. Some I got the nut off but you can see the thread damage so why go cheap. Tomorrow I will be driving the 70 miles to the factory and buy some "extras" just in case something else happens. The wife says "Bad charma out... Bad charma in..... I really thought I was a really nice guy....
Russ, I really don't know what you mean by checking my nuts. They threaded on very easily without any feeling of a problem. I'm using the ARP moly lube too. They only thing that seem to fit is I didn't use enough moly on the first 6. After that I really goobered them up and no other problems except the damn socket. The studs come thru the nut and hit inside the craftsman socket. It doesn't matter if its a deep or standard socket either. I checked it. So the top threads get ground down just a bit. The gaulded studs have the nut threaded down about half way of the fine threads. There shot. The ones that I was able to unthread shows the threads down deep all fuzzy and the black surface treatment is gone. I will be giving them back to ARP and they can inspect them. Maybe "they" did something wrong when they made them.
... They feel I didn't do anything wrong. Sometimes a small piece of dirt will cause this problem.... These nut to stud thread fit is called A3 or 3A.. I don't remember but its a higher grade than aircraft specs. Its the closest fit on the market. Way above Home depot or grade 8 but I already knew that much. Remember my almost 30 years working on the big steam generators and turbines plus the Pratt & Whitney jet engine peaker units...... We talked about the studs used in top fuel motors and they are 220,000 psi 9/16 so thats not much better than what we have. The only possible way we could use the 9/16 studs is to try it on a 6.9 motor because thats the only block that can handle the stud bore and tapping to 9/16th thread so maybe??? They do have some extrememly high alloy 260 to 270,000 psi studs but they cost around $1500.00 a set... Plus you can't touch them with your bare hands. The sweat will corrode them and cause a stress fracture and break. Not good. My Kens studs looked like maybe they had a corrosion problem at the threads or Nitrogen enbrittlement problem. Even having them tested they wouldn't show what really happened. So I take the responsibility for the corrosion problem and possible breakage. I really don't feel it was anything Kens supplier did wrong. As we were talking they asked about turbos. I told them yes, I boost to 12 lbs and no more... They kinda snickered because some guy had just called about all his psd intake manifold studs broke. They asked why and he didn't know.......
Geting old sucks.
The ring that has the number 1 thru 0 just spins around...... Damn it anyway. So off I go to get another one free from Sears.... Nope.... They have a 1 year warranty on torque wrenches. I argue this. I told this "kid" I've had this tool longer than he has been on the earth. And just maybe if he was alive when I bought it he might have been still shitten yellow...... Anyway I told them I wanted a new one and could prove when I bought it. I still had the sales reciete in my box. It was dated 1972. "Oh,, says the punk". They did have lifetime warrantys back then. So I take one look at what they say is the replacement tool.... What a piece o crap. Plastic and no way as good as what I have. So I paid $69.00 for a piece-o-crap to get my job done. No to try and fix my good old trusty wrench... Kinda figures that something would go wrong and keep me from finishing my work. Some of you guys know me from my posts. I have learned not to say what next because sure enough something is fixen to happen and it will only happen to me. Nobody has my lack of luck thats for sure....
