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 As the rotor is fully withdrawn from the stator core, THE FULL WEIGHT OF THE ROTOR MUST BE SUPPORTED BY THE CRANE.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.
