Synchronous Generators BG 132 / BG 160 Chapter 4: 4.5 Installation for single-bearing generators Installation NOTE For additional installation instructions for shaft fastening by tension bolt (instead of the grub-screw described here), please refer to section 4.5.4.4 on page 45. 1. Screw the supplied grub-screw (Figure 11/1) into the engine shaft as far as it will go using an Allen wrench. 2. Apply the sealing to the removed front end shield of the generator as described in section 4.5.4.1 on page 37. 3. Set the removed front end shield (Figure 11/2) with the sealing applied onto the engine flange and fasten it using the four screws (Figure 11/3). 4. Align the generator in front of the engine in a way, that the generator shaft lies in one line with the engine shaft. If necessary, support the generator accordingly. 5. Push the generator against the engine and align the threaded hole of the generator shaft to the grub-screw screwed into the engine shaft. 6. Screw the generator shaft by turning the fan impeller onto the grub-screw in the engine shaft as far as it will go. This pulls the generator housing against the front end shield already mounted on the engine. NOTE While screwing the generator shaft onto the grub-screw, align the generator with the front end shield mounted on the engine. It is not necessary to tighten the generator shaft on the grubscrew. It is sufficient, if the shaft is screwed onto the grubscrew as far as it will go, since the screw-connection tightens itself when the generator is loaded. For installation instructions for shaft fastening by tension bolt, please refer to section 4.5.4.4 on page 45. 7. Fasten the end shield to the generator using four fastening screws (Figure 12/2). 8. Remount the fan impeller shroud (Figure 12/1). Issue date: August 2002 43
