Getting ready to install the tail feathers for the last time . I searched but could not find the torque specs for the jam nuts on the heim bearings.
Vans service bulletin does not specify a torque setting ( as far as I can see )

Jam nuts AN316 use same torque as shear nut application..
..even though you would think they are a "tension" application the thin nut uses "shear" torque.
AN316-6 (3/8x24) = 110 in lbs.
AN316-5 (5/16x24) = 80 in lbs.
Straight from Robinson helicopter R44 maintenance manual for jam nut torques. That's good enough for me.....

That's the same as 43.13 shows , works for me . I made a compact 9/16 crowfoot wrench to to it properly.
