I have a spring guage to test preload and everythings good until I go to torque the lock nut. I'll get the adjusting nut set and my preload will read 10 to 12lb on the spring scale, but when I go to torque the lock nut down to 57 ftlb or whaterver Hayes says, my preload increases to 15lb. If I loosen the lock net a bit I can get the preload back to the upper end of the spec of 12lb.
So my question is what's more important to have in spec, the preload or the torque on the lock nut? Hopefully that makes sense.
