Not only do we offer our CNC machined pulley for Delco Alternators and Generators, but we also offer a CNC machined wide belt pulley for the small mainshaft Denso pint size Alternator as well. We use this same pulley in our 12V conversion kit for the model C & CA model Tractors, as well as the model G Tractor. Machined specifically for the 15mm mainshaft on the Denso unit.
