I have a Ceadarapids 111 Pitmaster that has a tired D318 Cat power unit on it, and I want to repace it with a 471 detriot. The machine has a large flat belt and all mechanical drive. The main issue that I can see is the Cat is +-60 hp and is governed (according to the tag) at 1600 rpm, the detriot is from a Koehring 466 excavator, and probaly has more power and turns faster. I think that it could be governed to run slower, but not sure on this. Any helpful suggestions would be appreciated. On second thought, maybe this should be in "old Iron"
