Having started up the coupling the tightening torques of the screws have to be inspected
during the usual inspection intervals.
Disassembly:
STOP
Driving components falling down may cause injury to persons or damage on the machine.
Secure the driving components before disassembly.
•
Unscrew the clamping screws evenly one after another. During every revolution every screw may only be
unscrewed by half a turn. Unscrew all clamping screws by 3 - 4 pitches.
•
Remove the screws located next to the extraction threads and screw them into the respective extraction
threads until they fit.
•
The clamping ring is released by tightening the screws in the extraction threads evenly gradually and
crosswise.

•
In case of a repeated assembly the hub bore and shaft have to be cleaned and afterwards lubricated with a
thin-bodied oil (e. g. Castrol 4 in 1 or Klüber Quietsch-Ex). The same applies for the taper surfaces of clamping
ring hub and clamping ring.
!
If these hints are not observed, the operation of the clamping ring hub may be affected.
