8.4 Dismantling the coupling
50 Edition 09/2022 M3560-02en
Procedure
1. Secure the coupling parts to prevent them from falling.
2. Remove the axial locking element (set screw, end plate).
3. Use a suitable pulling fixture.
4. Heat up the coupling part 1 (1) and/or 2 (2) using a burner above the parallel key along
its length to maximum 80 °C.
5. Pull off the coupling part 1 (1) and/or 2 (2). Use suitable lifting gear when doing this.
6. Check the gear, the sealing surfaces, hub bore and shaft for damage and protect them
against corrosion.
7. Replace damaged parts.
When reinstalling the coupling parts, please observe the information in Chapters Assembly
(Page 25) and Commissioning (Page 39).
8.4.2 Dismantling coupling part 1 (1) or 2 (2) with shaft-hub connection using
pressurised oil interference fit
8.4 Dismantling the coupling
DANGER
Oil pressure in excess of maximum permissible value
The coupling could burst if the maximum pressure indicated in the dimension drawing is
exceeded. 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.
• 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.
DANGER
Danger as a result of improper handling of fixtures and pumps
Failure to handle fixtures and pumps properly can result in injuries. The coupling can burst.
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.
• Please observe the manufacturer's instructions on handling the following tools:
ð Pulling fixtures
ð
Pumps
WARNING
Risk of injury as a result of coupling parts or the pulling fixture working loose.
Coupling parts or pulling fixtures can work loose and fall when dismantling work is in pro-
gress.
• Use suitable hoisting gear to hold the coupling part 1 (1) or 2 (2) and the pulling fixture
in position.
• Attach an axial locking element if the pressurised oil interference fit is tapered.
