Bore diameter
WARNING
Danger due to bursting of the coupling
If you exceed the maximum diameter of the finished bore, then this can cause the coupling
to burst in operation. There is a risk of fatal injury from flying fragments. If a coupling bursts
in an area at risk of explosion, then this can result in an explosion.
• Adhere to the maximum diameters specified.
Procedure
1. Remove the coupling parts to be machined:
– For part 1: Remove the flexible elements (12)
– For part 11 FNDS-HB: Remove part 8 and part 10
– For part 11; 32: Remove part 10
– For hub carrier part (120): Remove hub carrier part (120) from coupling, remove O-
rings (117, 138) and retain for reapplication later.
2. Remove the preservation and clean the coupling parts to be machined.
3. Clamp the coupling to the areas marked with in the diagram below.
4. When machining the finished bore into the hub carrier part (120), also finish-turn the
axial run-out surface of the outer flange during the clamping operation (depth of cut 0.2 ±
0.1 mm).
5. Machine the finished bore in accordance with the diagram below.
