[QUOTE]140 lb and leave it there?/QUOTE]

Gary I must be mixing my english and my hickaneese. The 100-140 lbs torque is on the jamb nut not the bearing adjusting nut. The first nut (adjusting nut) is like you said tightened to seat the bearing and then backed off(no preload) a notch (as you do) or 45 degrees or 1/8th of a turn. Then the jamb nut is torqued.
Sorry for any confusion.
