I have full hydro steering and occasionally the steering gets hard then goes away just as quick and turns great. I asked the manufacturer and we came up with nothing. This last weekend though i noticed that the reservoir is lower than the orbital valve. Is this possibly the problem? if so, where are people mounting the reservoir when the steering wheel connects to orbital with short(like 5") shaft? If i mounted my reservoir above orbital, it'd be sticking out of the hood like a foot.
