Hydraulic Assit Steering- Another Idea Never Attempted

[Lieutenant Dan]

Ok I have been reading threads for a week or more now on power steering and have done my home work or atleast I think I have.....

This will be one of the first mods I will do when I get my deuce in February. I have seen many different ways to do it from the drag link valves to the full steering box swaps.

I have a different idea idea then most, and only seen it mentioned in one thread.

why hasn't anyone piggy backed a orbital valve with the original steering shaft?

Basically leaving the entire original steering system intact and mounting the orbital valve on the frame rail with a custom mount under the steering shaft. You could then take a sprocket from say tractor supply use a chain to link it to the steering shaft. It would basically be the same turning rate as if it where mounted to the fire wall. You could also change the ratio of the sprockets to have the valve be quicker then the steering stem or slower. Basically you'd have to find a sprocket the same size as the steering shaft or bore it to fit then split it in half put it over the steering stem and weld it on.

then use a 5 ton MF pump and you could go one of two ways for the cylinder. Mount it to the axle housing and connect it to the tie rod tube or mount it on the passenger frame rail and have it turn another knuckle on the other side of the axle.

this could easily be done with some time and around maybe $500 to $600 bucks. You can get orbital valves new from eBay for around $300 or use one from a junk yard. I have access to a few junk jockey trucks with full hydro steering that I could salvage the steering valve cylinder and lines from so I might be able to do it for even cheaper. And since it's a hydraulic assist off the original system failure wouldn't cause total loss of steering.....

tell me if I'm thinking wrong here or what.

We had a few farm tractors we did this too, well kinda like this and they worked great!

It's been done. And an even easier way is to use a servo instead of a valve. Or you can go with the brute force method of a char-lynn forklift steering assist that "forces" the stock steering box to turn. I've got one of those boxes brand new that I haven't gotten around to doing anything with.

There's more than one way to skin a cat as they say.

 

[Lieutenant Dan]

I could only find one post that said anything about something like this. Most posts where full hydraulic or the ross hf54 or saginaw swap.

[Lieutenant Dan]

That doesn't sound like a bad idea but sounds weak.

There's just no way to make him like it.

Eastern surplus and c&c equipent offer a kit that uses the char lynn torque generator. Seems to work pretty well but get ready to pay up. There are cheaper ways that are just as effective or at least close.

 

[gimpyrobb]

There are some hydraulic steering kits out there that work just like the air-assist, except they use hydraulics. I know one guy that installed that system and it works real nice.

 

[welldigger]

Hey gimp. You know how they actuate the cylinder?

 

[Lieutenant Dan]

Yeah I can't see spending $2000 to $3000 for a kit that's crazy.....

Yeah gimpy how did the control the cylinder. I couldn't seem to find to many threads on the assist setups besides the drag link valves

I'd go the ross hf54 route I just can't seem to find one. There are a few places online I searched and called and most don't answer or phone numbers were disconnected.

 

[Lieutenant Dan]

Why couldn't a 5 ton system be used with 14.00r20?

All i see is the box is to big to be used with 53" tires..... Would they work with 49" tires?

i can get a entire 5 ton setup for a good price from the guy I'm buying the truck from. Comes with everything pump (cummins pump) steering box column cylinder everything!

 

[gimpyrobb]

The 5ton steering box doesn't fit between the frame and the driver's side tire. It can but you need to make WAY more modifications than necessary.

Check post #13 here. Pics of the Garrison hydraulic unit I posted about:

[patracy]

Simple. Size.

 

[Lieutenant Dan]

That is a great way to do it but I can't find them things anywhere.... I checked eBay and tried calling there number on the website to no avail.

im gonna stick with my idea seems simple enough and probably cost a tad more the it would just buying the ross steering box.

 

[patracy]

I would look into the servo setup then I mentioned earlier instead of trying to go down the path of the orbital valve, sprockets, and such. Much simpler path and far easier to adjust.

 

[gimpyrobb]

Well, there is a guy that put a saginaw box on his deuce. He had a hydraulic ram powered off the steering boxes ports. Let me see if I can find that one...

 

[gimpyrobb]

Its about halfway down the page. He said he used a reverse rotation box found on dodges and fords, and a 2x10 ram.

how are you going to mount it??

 

[Lieutenant Dan]

Mount what?

Im in actually looking at doing a torque generator now instead of the idea I had before. I found one at a good price and they are very simple operation. A pump, reservior, pressure relief valve and the torque generator.
