Maintenance N-EUPEX Maximum permissible torsional backlash In order to calculate the torsional backlash, rotate one coupling half without applying torque up to the stop. Mark both of the coupling halves in the way shown in the diagram below. Turn the coupling part in the opposite direction up to the stop. The markings on both halves will then move apart. The distance between the markings corresponds to the torsional backlash.
