Default hydraulic steering ?s

ok. I have a sbc in my toyota with a 1988 chevy serpentine kit. I have been looking into putting a full hydraulic steering system on my truck. I am still running a toyota solid axe in front. It still has a factory steering system in it.

#1 - can i use the stock GM power steering pump? (YES)

#2 - do i really need to convert to a high steer arm? (NO, but im probly going to)

#3 - Is this going to be to quick in my aplication? 6" stroke x 2.25" bore hydraulic ram + 6.1 orbital valve = 2.7 turns lock to lock.
(1980 toyota 4x4 short wheel base)

stock pump will work fine

shouldnt have to switch to hi steer, I ran mine with the stock tie rod for a couple years

I'm assuming your planning on using a single-sided cylinder? Thats all I had on mine, and just built a truss on the axle housing and attached the cylinder to that

i use a ported stock pump. west texas offroad will show you how to get the pump to flow a little more for pretty much free. get a big ps fluid cooler to cool and add capacity.
im running a single ended ram on the back side of the axle to keep it a little more protected. it goes to a double ended high steer arm on the passenger side.
it has a solid aluminium tie rod with heims on high steer arms in front of the axle.

if your gonna go hydro, go high to keep it protected!

Is this going to be to quick in my aplication? (1980 toyota 4x4 short wheel base) I would still want to be able to drive this thing a speed. Playing on the drad strip at the dunes ect...

#1 - Yes

#2 - Don't have to

#3 - No, 2.7 turns lock to lock sound similar to many stock applications.

3-3.75 turns is common for stock applications, it'll be slightly quicker but nothing too excessive. 2.5 or higher and you'll be fine.

It should be cubic inches per revolution, and it looks like 6.1 will get you 2.7 turns with their system and a 6" ram.

If I remember correctly, I have a 7.3 cu/rev valve and a 10"x2.5 which will give me just over 3 turns lock to lock but that's over 48 or so degrees so it'll be a little fast but not too far outside of the window.

Do you have more info on these Ford trucks?
I have an orbital that supposedly came out of a 2007 Ford truck, but I can't find any specs on it anywhere.

Post a picture of this "orbital valve" that you got off a ford truck.

Are you sure it isnt a steering box?

Yeah I am alomost positive that this is an orbital valve, might not have started real well with my misreading forK truck, guess I was excited to find someone who may have one of these, but I do know the difference between a steering box and an orbital valve. I guess it would have had to bean a large truck of some sort, guy told me some trash trucks have full hydro on them? I called a local truck parts place and they showed nothing that matched the numbers, I am going to try a larger Ford dealer in K.C. who sells big trucks and has a big parts department to see if they know anything. I appreciate any help someone can offer, I am going to run it regardless, just wondered what the specs where. I will post the part numbers if anyone can find something with them, I have put them in every search engine I know and got nothing.

Your best bet is going to be finding it's original application and then find out what it was powering and work backwards from there. You might have some luck finding information on pirate, theres a lot of people there who find old orbitals and decipher them. If it comes down to it, you could always hook it up and see what you get, worst case would leave you buying a new ram or orbital. Best case, you saved $350....

I'm curious to see what that came off of.

How many times can one idiot misread "fork" as "ford" obviously twice, dumb a##, I bought it from a guy on here, this is the post he had for it on here

So, now that I have managed to look like a total fool, anyone know anything about this valve, maybe trailrig can chime in?
