Hello, I have a old hyster forklift what I think is a Challenger 80 (but not sure there is no tag). This machine hasn't been used in 4 or 5 years, and I have no steering. Oil level is good, there is only one pump so the mast works. I have oil coming to a priority valve under the floorboard towards the front on the left side, but no oil going up to the orbital motor, what has me confused is there is only two lines going to the orbital motor from that valve. If anyone has any idea or can help me that would be greatly appreciated.
