Greetings Tom . Can't answer your question about the pump you have but have you considered trying to find a way to mount it to the front of the tractor with the shaft side to the engine ? I'm in the middle of a project adapting a snow plow to one of my tractors and I'm using a saginaw reverse rotation p/s pump and it will be mounted on the front of the tractor and it will be driven directly off the front pto shaft .
Mike
