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).
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 2 (2) or 20 (20).
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 74) when replacing the buffers (5).
6. Secure the buffers (5) with the washers (6) and the locking rings (12).
7. Insert the bolts (4) with the buffers (5) into the bolt fitting holes. Observe any markings
that might be provided.
8. Push the washers (8) onto the screws (11).
9. Apply a small quantity of liquid screw locking agent (e.g. Loctite 243 medium strength) to
the screws (11).
10.Secure the bolts (4) with the screws (11) and washers (8).
11.Tighten the screws (11) to the specified tightening torque T
A
(see section Tightening
torques and widths A/F (Page 72)).
