NOTICE
Blockage of cross bore of bolts (4)
The liquid screw locking agent can seal the cross bore of the bolts (4). Pressing out the
bolts (4) with grease then becomes difficult or completely impossible.
• Apply only a small quantity of the liquid screw locking agent to the screws (11).
Procedure
1. Remove the bolts (4). Please observe the relevant information in section Pressing out
bolts (Page 47).
2. Remove the locking rings (12) and the washers (6).
3. Pull the buffers (5) off the bolts (4).
4. Clean the bolts (4), the washers (6), the locking rings (12), the buffer fitting holes and the
bolt fitting holes in the coupling parts 1 (1) and/or 3 (3).
If old bolts (4) are to be reused, the tapped holes and cross bores must be completely
free of any residues of grease or liquid screw locking agent.
5. Mount new buffers (5) on the bolts (4). Please observe the information in section Use
and storage of the buffers (5) (Page 73) when replacing the buffers (5).
6. Secure the buffers (5) with the washers (6) and the locking rings (12).
