Adjustment of Ball Pivot Screw

Always adjust the ball pivot screw so that the ball pivot just touches the bottom of the hardened pivot cut, no more, no less The ball pivot tolerances should be checked regularly. If the ball pivot does not touch the pivot cup, you will be able to press down on the truck assembly and feel or see a slight motion-up & down – of the ball pivot into the pivot cup. Adjust the ball pivot screw until the pressure applied to the truck assembly no longer results in this movement. When satisfied that the ball pivot is resting with slight tension in the pivot cup, hold the pivot screw with one wrench while tightening the pivot screw lock nut with another, do not over adjust. If the ball pivot is forced into the pivot cup too far it will result in unreliable skate action and place excessive strain on king pins. Be sure to check your pivot pin action for proper seating monthly.
