MG MGA - head studs
|I was tearing down a cylinder head yesterday and there is the number 22 stamped on the end of the studs. I seem to remember that this indicated a high strength stud, is that correct?|
|Thats what I thought George, but even Peter Burgess could not confirm it! He said they are all good!|
|George,drop Barney Gaylord an email. He will know the answer.|
|In the Haynes for my 73 midget it has drill dot or '22' at a higher torque setting but as the dot was on only 4 (or 5, I forget) out of 9 studs we ignored it.|
|Colin, I searched on Barney's web site and didn't find anything about those studs. Maybe I will send him an email.|
|From the Moss Europe catalogue, p 10 bottom right side under Cylinder Head Technical Information: |
"Start at 25 ft/Lbs., go to 40 ft/lbs and finish at 50 ft/LBS. Studs with a dot or a 22 on the end will take more torque than the unmarked studs. It is safe to torque these to 60 ft/lbs, but only if all studs are so marked."
My catalogue is dated March 2012.
|Thanks Dominic, that confirms my foggy recollection! I'll look at my Moss USA catalog to see if the same info is there. I did not know that the "dot" also indicated a high strength stud, more MG trivia to fill my head with...|
