IH had Kohler paint the engines Federal Yellow for Cub Cadets so they wouldn't have to mess with masking and painting in their factory. The Starter/Generators were installed and also painted yellow by Kohler (starter belts got overspray) until late in the 1x6/7 Series production or the beginning of 1X8/9 Series. IH realized that they could source the S/G's themselves cheaper, due to their buying power, and install them at the factory in Louisville and save money. Of course, Kohler had to adjust their price down since they no longer had to procure, paint or install. IH just used the black finish that Delco Remy applied in their factory.
