I am re-vamping a generating plant that was left at my shop with a destroyed engine. To do so I am replacing the scrap engine with one from the farm irrigation system. The outboard bearing on the generator engine also served as the front support bearing for the generator. The replacement engine has a 3/4" straight shaft consequently I have mounted a bracket that supports a flange bearing on one side and the generator front bell housing on the other. The replacement engine will turn the generator through a Love-Joy coupling.
Since I did not pay much attention to the rear bearing during dismantling my question is; how to find the horizontal magnetic center of the generator? There is no shoulder other than a plate holding a capacitor in the rear bell housing. The bearing is supported by an "O" ring midway through the bearing raceway. The Love-Joy coupling is a series 95 and can be adjusted along the axis of the shafts up to about 1/2".
A new base plate will be made to support the replacement engine and generator so there is potential for necessary adjustment. The damaged engine had two cushion mounts and the generator had one at the rear of the unit, I intend to support the new base plate with a cushion mount at each of the 4 corners.
Any help will be greatly appreciated.
