8.3 Replacing wearing parts
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).
When removing the bolts (4), please observe the information in section Pressing out bolts
(Page 47).
Procedure
1. Remove the hexagon head screws (11) and the washers (8).
2. Remove the bolts (4) with the buffers (5) through the buffer fitting holes.
3. Pull the buffers (5) off the bolts (4).
4. Clean the bolts (4), the washers (6), the buffer fitting holes and the bolt fitting holes in
the coupling parts 1 (1) and/or 3 (3).
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. Insert the bolts (4) with the washers (6) and the buffers (5) through the buffer fitting holes
into the bolt fitting holes. Observe any markings that might be provided.
7. Push the washers (8) onto the screws (11).
8. Apply a small quantity of liquid screw locking agent (e.g. Loctite 243 medium strength) to
the screws (11).
