Dismantling

Disassembly instructions
The drawings and parts lists do not contain any detailed information about the type and
dimensions of retaining elements and the like.
Notice
Before you start dismantling them, you should therefore mark up the respective assignment
of retaining elements and the layout of the internal connections for assembly if they have to
be disconnected for maintenance work.
Notice
Use pullers or suitable devices to disassemble parts and components attached to the motor
shaft.
Three-phase motors of a vertical type of construction can be dismantled in the horizontal
position.
Working with three-phase motor in vertical position
Notice
When working on the locating bearing when the three-phase motor is in its vertical position,
support the rotor.
When attaching the rotor in a vertical position, make sure that the centering recesses in the
shaft ends (DIN 332) - DS M24 have a recessed thread; DIN 580 eye-bolts are unsuitable
because only a few threads would be engaged.
