Alternator Bell end modification?

[Satamax]

Hi everybody. 

Well, my generator set is on it's way out i think. The 6-71 overheats. Has clunking noises etc. 

I have a big diesel v8. 270 din hp. 11 liters. Only 109 hours. 

But the alternator is a single bearing. So adapting the thing on the new motor is complicated. 

Has anybody seen a single bearing  alternator transformed into a dual bearing, with a new bell end?  

Thanks a lot. 

Max.
