The jamb nut broke from the ground shield at 36ft.lbs then the torque wrench clicked. It broke but it had not completely separated. It took 38 ft.lbs for it to completely separate and come apart.
One thing I noticed is that the porcelain piece that broke off and stayed in the ground shield came right out when I turned it over. Obviously you can't turn it over when it's stuck in the head but I wonder if it could be sucked out with a shop vac instead of having to break it up to get it out. Then you could easily tap the ground shield so it can be removed.
I may do another later and record it for the heck of it.
