DANGER
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. Secure the coupling parts to prevent them from falling.
2. Move the coupled machines apart.
3. Unscrew the screw connection (25) and remove the rubber disk element 5 (5) and/or
6 (6).
4. On types ESNW and ESDW, you can pull off the complete assembly comprising the
coupling part 1 (1) with the mounted flange (101) and the coupling part 3 (3). If you want
to remove the flange (101) and the coupling part 3 (3), remove the screw connec-
tion (125 and 31).
5. Remove the axial locking elements (set screw, end plate).
6. Use a suitable pulling fixture.
7. Heat up the coupling part 1 (1) or 2 (2) using a burner above the parallel keyway along
its length to maximum 80 °C.
8. Pull off the coupling part 1 (1) or 2 (2). Use suitable lifting gear when doing this.
9. Check the hub bore and the shaft for damage and protect them against corrosion.
10.Replace any damaged parts.
When reinstalling the coupling parts please observe the information in chapters Assembling
(Page 27) and Commissioning (Page 39).
