Im attaching the bell crank brackets, W-823PP. The AN3-6A bolt threads into a K1000-3 nutplate.
The bolts are threading in smoothly and gets stiffer as I get closer to the bracket that I'm bolting on. I get the bolts to the point where they and the washers are just touching the bracket. When I get my torque wrench (set for 23" lbs) out for the final fit it "clicks" immediately without tightening it any further. The bolt appears to be tighter than 23" lbs even before I get to the bracket. I've even backed the bolt out to where the washer could freely spin and the torque wrench does the same thing. Obviously having a tight nutplate is good, but isn't this over-tight? Have you run into this before?
