Can you use your steering box to go full hydro, just not use a drag-link? I am just pondering on what to use for my next plan on full hydro. Thanks for any help.

WOW!! :shaking:

NO you cant

did you mean use your stock power steering pump, if so yes

you will not use a steering box on a full hydro setup, hydro assist yes

define exactly what it is you are doing

I think he wants to use the valving that's in the stock power steering gear box. The answer is no, you can't to it. The stock power steering box uses a different type of spool valve than the full hydro valve. The stock system relies on a torsion rod to determine the fluid flow. The rod "twists" when the steering is under load. The more the rod "twists", the more fluid is sent to the piston thus more turning force. Since it uses this torsion rod, you need a mechanical linkage (pitman arm & draglink).

Balsax hit it on the nose on what and why I can't. Thanks for the answer, I kinda figured but wasn't 100%.

the valve has no way to meter fluid into the cylinder. With a steering control valve there is a gerotor to meter the oil, larger gerotor faster steering smaller/ slower

the valve in a steering box would be on or off with little or no control of how far you steered the wheels right or left

the "gear train" in a steering box sets how fast you steer left to right and the valve provides assist, in a steering control valve there is a very similar valve as a steering box but it provides assist to the gerotor.

Next stupid question I have about steering! I redneck guy A know (olderfart) told me that rack and pinion is just the about the same as hydro as in the steering box for it will work because it doesn't have a tie between it and the actual steering. HHMM.. Lost. Is he old fart or old smart? Sorry If I am stupid but I am just thinking out load and have some smarts on engineering but not alot. I am better at structours. Thanks even if ya flame me! :flipoff2:

with rack and pinion you have the rack and pinion as the gear train

and there is a piston that is made into the rack when you steer right the "assist valve" (when steering force is enough to crack the valve) adds assist to the left side of the piston helping to push the rack right

the pinion (when there is not enough resistance to crack open the valve) still alows the steering to move

also as you hold the steering wheel on one spot the outside world may be affecting the wheels, which affects the box or rack and pinnion. the load on the steering is countered by the assist valve even though you might not be turning the wheel

make since?

Yes it does, Kicking old man in ass!!!

your in IN, just use old JD combine parts out of the scrap yard. it will work FINE and be cheap
