Quite possibly, as I started by taking them all to 20 ft-lbs, then went to 38 on all and did my first stretch measurement.
Typically they came in between 0.0060 and 0.0075 at 38.
With the exception of the one bolt that hit the mark at only 38 ft-lbs. I'm now wondering if that bolt is weak and should be replaced.
However, on the ones that are high, like 50 & 52, I backed off a quarter turn and re-torqued to the amount shown to get adequate stretch.
This was the third tightening of the bolts.
1st was when the rod ends were resized by the machine shop.
I measured them before I loosened them, then again after they were undone.
2nd was when I was measuring my bearings with a dial gauge.
I took them to the recommended stretch at that time. Highest torque required at that time was 47
Then measured them again loose to ensure they had no permanent deformation.
3rd was going on the crank last night.
