Install Torque Procedure
Method one: 55-65 Ft-lbs
Method two FFWR (best method): 1.0 Flats from Wrench Resistance. Tighten the nut lightly with a wrench (approximately 30 in.lb.) This is considered the wrench resistance position. Starting from this position, tighten the nut further by the number of flats listed above. A flat is referred to as one side of the hexagonal nut and equates to 1/6 of a turn.
