WARNING: The rope sling may not be at the centre of gravity of the rotor, and guidance at the ends of the
rotor is essential.
As the rotor is fully withdrawn from the stator core, THE FULL WEIGHT OF THE ROTOR MUST BE
SUPPORTED BY THE CRANE. If the core is allowed to drop more than 6 mm at this point, it will
make contact with the stator windings, and may damage them.
Re-Assembly
Reverse process of the above.
