Restoring a 1250 that had no starter/generator when I got it. I've rebuilt a S/G off a tube frame, but it cranks the engine too slowly. It has a pulley that's about 2 1/4" outside diameter. The parts catalogs show different part numbers for the pulleys between a 1050 and a 1250.
For owners of large frame tractors with Wisconsin S12D or S14D engines, I'd like to know what is the outside diameter of your S/G pulley so I can get the right one.
