Make sure that the mating structure is not damaged. Do not pluck any bores or use  at headed bolts or rods for pushing
the electric machine out of the mating structure.

For dismounting the electric machine, follow the steps below.
1. Install correct lifting eyes to the lifting bores in the machine frame, and the lifting slings to the

lifting eyes. Support the machine with lifting slings when dismounting. Refer to Chapter Lifting.
2. Loosen the mounting bolts, for more information refer to Chapter Mounting the electric machine.
3. If axial force is required, use the bores in D-end  ange to push the electric machine out from the

mating structure.
