Take a look at that serial number on the Big 20. If it is HG, unit is 1976, if JG, 1986. I am guessing a 1986 since the earlier Big 20's used the F163 engine, the Y112 being used later - smaller engine. We probably have starter for it. The earlier Big 40 diesels used 4 cylinder Continental engine, later ones a 3 cylinder. I don't think you would have a prayer of putting 20 generator on 40, but make sure you want to as there are many pieces around for both units. The 20 has an auto alternator, belt driven, on the end of generator - that is the exciter. Thanks, weldersales
