Hello there I have an old hyster forklift which I think is a H80 (there's no tag). It has a ford engine ran off propane. I have no steering at all and what has me confused is there is only two lines going to the steering orbital motor. I checked fluid and it is full, it has only one pump for the hydraulics and steering. If anyone has any info on this or where I could start to find the problem that would be great. I have oil coming to the relief/priority valve but nothing going to the steering orbital motor, but the two lines really have me confused.
