From what I understand and seem to remember hearing is if the power steering pump that was on the generator as the cars and trucks of that era locked up for any reason the shaft on the back of the generator would sheer off. I used to have a couple of those generators for a 55, 56, or 57 Chevrolet car and they were both sheered off. It might be worth using the pump for a later model that is not driven off of the generator. Just a thought.
