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. Prepare the electric machine for lifting, for more information refer to Chapter

Lifting

on page 25.

Support the electric machine with lifting slings when dismounting.

2. Loosen the mounting bolts. For more information refer to Chapter

Mounting the electric machine

page 31.

3. If force is required, use the bores in D-end flange to push the electric machine out from the mating

structure, or use some other method that does not damage the electric machine.

4. Lift the electric machine off. Support the electric machine when lifting.
