Procedure
1. Check the wear on the flexible elements (12) (see section Maximum permissible torsional
backlash (Page 44)).
2. Replace the flexible elements (12) if necessary (see section Replacing wearing parts
(Page 45)).
7.2.3.2 Correcting the changed alignment
A changed alignment of the coupling during operation often occurs when the coupled machines
shift towards one another. A cause of this can be loose foundation bolts.
Procedure
1. Correct the cause for the change in alignment.
2. Check the wearing parts for wear and replace them as required.
3. Check the locking elements that prevent axial movements and correct these as required.
4. Realign the coupling.
