Note
Shorter maintenance intervals
If necessary, set shorter maintenance intervals depending on actual wear.
8.2 Maximum permissible torsional backlash
In order to calculate the torsional backlash, rotate one coupling part 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.

8.3 Replacing wearing parts
WARNING
Danger due to bursting of the coupling
If you do not observe the information stipulated here regarding replacement of wearing parts,
this can lead to bursting of the coupling during operation. There is a risk of fatal injury from
flying fragments.
● Please observe all the stipulations concerning the replacement of wearing parts.
Replace the cam ring (20) if the maximum permissible torsional backlash has been reached.
