I suggest that you call Warner and see what you can do. As I mentioned I called them yesterday but maybe you as the owner can get them to help you. They crossed the Cub part number to a Warner # 1427-4

Other than that try an electric motor shop to see if they will rewind that coil. Bearings should be available from a bearing shop or on line.
