Disassembly of dual-bearing generators (BG 132 and BG 160 models)

10.3 Disassembly of dual-bearing generators

(BG 132 and BG 160 models)

The disassembly of dual-bearing generator must be carried out according to

the descriptions in the Installation chapter.

Installation of generator, page 28

10.4 Disassembly of single-bearing generators

NOTE

The following special tools are necessary for the disassembly of

single-bearing generators:

Special tool provided by the motor manufacturer for locking the motor

shaft.

For shaft attachment via grub screw: special hexagon nut for turning the

generator shaft with a screw spanner as well as special saw ring pliers for

removing and attaching the saw ring for securing the fan wheel on the

shaft.

For shaft attachment via pull rod: rod and set screw.

Additionally for brush generators:

Insert the special wooden wedge for the transportation lock of the rotor.
