8.4 Removing coupling part 1 (1) or 3 (3)
M3602-01en Edition 09/2022 49
• Removing coupling part 1 (1) or 3 (3) with shaft and hub connected by a parallel key
(Page 49)
• Removing coupling part 1 (1) or 3 (3) with shaft and hub connected by a pressurised oil
interference fit (Page 49)

8.4 Removing coupling part 1 (1) or 3 (3)
WARNING
Danger from burners and hot coupling parts
Risk of injury due to burners and hot surfaces. Burners or hot coupling parts can lead to an
explosion in potentially explosive atmospheres.
• Wear suitable protective equipment (gloves, safety goggles).
• Ensure that the area is not at risk of explosion.
Procedure
1. Move the coupled machines apart.
2. Secure the coupling parts to prevent them from falling.
3. Remove the axial locking element (set screw, end plate).
4. Use a suitable pulling fixture.
5. Heat up the coupling part 1 (1) and/or 3 (3) using a burner above the parallel keyway
along its length to maximum 80 °C.
Note when doing this the permissible temperature range of the buffers (5) (refer to sec-
tion RUPEX buffers (5) (Page 74)). Remove the buffers (5) if necessary.
6. Pull off the coupling part 1 (1) and/or 3 (3). Use suitable lifting gear when doing this.
7. Check the hub bore and the shaft for damage and protect them against corrosion.
8. Replace any damaged parts.
When reinstalling the coupling parts please observe the information in chapters Assembly
(Page 25) and Commissioning (Page 35).

8.4 Removing coupling part 1 (1) or 3 (3)
DANGER
Oil pressure in excess of maximum permissible value
The coupling can burst. There is a risk of fatal injury from flying fragments. Bursting of the
coupling can lead to an explosion in potentially explosive atmospheres.
• Do not exceed the maximum oil pressure specified in the dimension drawing.
• Keep the oil pressure constant in all oil channels during the entire procedure.
