Removal for shaft fastening by grub-screw<br />
1. Remove the fan impeller shroud (Figure 31/4) <strong>and</strong> the fan impeller (Figure<br />
31/3) from the generator. The fan impeller is secured against twisting on the<br />
shaft by means of a feathered key <strong>and</strong> a sawing ring.<br />
2. Attach the special hexagon nut (Figure 32/2) onto the generator shaft<br />
instead of the fan impeller <strong>and</strong> secure it against twisting by means of the<br />
feathered key (1).<br />
3. Hold the engine shaft using the special tool of the engine manufacturer.<br />
4. Attach the spanner to the special hexagon nut <strong>and</strong> undo the grub-screw<br />
connection between engine <strong>and</strong> generator shaft.<br />
5. Support the generator if necessary <strong>and</strong> unscrew the four end shield fastening<br />
screws (Figure 32/3) at the engine flange.<br />
6. Unscrew the generator shaft from the grub-screw screwed into the engine<br />
shaft <strong>and</strong> detach the generator.<br />
7. Unscrew the grub-screw (Figure 32/4) from the engine shaft using an Allen<br />
wrench.<br />
