Hyd steering?

[Tay-J]

Posted this in the general section before but it is more suited for this area. I would like to hear back from someone...anything!

Looking if anyone has done this, if so how was it done?

I want to use the hyd steering setup out of a forklift. I already know I would need to rebuild everything with new seals and shorten the stroke to match that of my axle. I can get the whole setup cheap out of a forklift that is in a junk yard. It was a propane engine forklift.

Any info anyone may have could help!

Never heard of it? I know nothing about forklifts, but where there's a will....well you know the rest! If you try it, be sure and post pics etc.!

Hydro steering is not street legal in AZ. or most states they require mechanical link to the knuckles as it where. You can do Hydro assist and be legal. If this is a trail only rig then you can convert it. There are plenty of good write ups on full hydro steering on pirates4x4.com. and remember that the steering system on a fork truck is not self centering

I looked on pirate but coul dnot find a simular build that was any help. And I don't plan on keeping it street legal which means it also doesn't need to be self centering. Looks like I will just tackle it and see how it comes out.

I just found 20 at least and your thread where they where trying to help, if you cant take a basic build idea and put it to use using the info you already have been given, you have no business in trying to do this type of fab work.

contact they guys over at desertFab, they do them all the time for the rock buggies they build

Hydro steering is not illegal. There is nothing in ARS that say anything about hydro steering being legal or not. I do know that forklifts and backhoes both drive on the street here and they are both hydro. I seriously if it was illegal that any cop would know or care anyway. If it is your DD then go assist. If it hardly ever sees road then go full hydro.

Haven't checked my thread on pirate since friday, don't know what else has been posted yet. Im glad you found twenty threads, I personally can't stand reading through old threads of endless c rap just for two sentences that are usefull. Now when I did look on pirate all the hydro steering threads I found were about some kit someone bought and installed....that tells me nothing. And just so you know my business in this type of work...hydraulics is my job meaning the rebuild will be nothing, I was only looking to see how someone may have set up the same type of steering. I will give the guys at desert fab a call and see what they may know. Thanks

I agree, some old fords are full hydro steering. And other large vehilces are full hydro.

Found some good ideas on pirate. Saw some knuckles a guy welded some brackets on to make them high steer, first time I saw that but he says it works well. After it is all done I will post up the whole project.

[Shane]

I read your thread over there. His knuckles are scary looking, but that is me...

Honestly....it did look scary. I did like the skid he made though for the front end.

Well...Im computer stupid! Give me a wrench and I can do all kinds of stuff, give me a computer and we will be lucky if it gets turned on. I know it is all easy stuff, I just care not to know. Good thing there are other who will post links for me, thanks Shane!

It takes alot of work to get hydro steer to work so you can drive it at any speed, You get steering lag,you need to match stroke cylinder size, pump flow etc etc. If you are going to drive between trails(even at say 40mph) you need it to be a good set up for your own safty! If it was me I would look at hyro asist, I had a AGR kit on my cj that was very good! great Quality, this would be my pic! bit if you have a trailer Queen thats different.

Well for the hydro steering I have decided to just go with the assist instead of full hydro. There are a few trails I am planning on running that only go one way so I will need to drive it on the street at some point. I am also going to end up just dumping the money on the whole kit for the assist even though with time I could put it all together. I am getting tired of trying to do the budget thing and always hunting for parts that might work, new parts are always fun too!

what kit are you going for?

[howyadoin]

I don't think Itsacj6 likes you very much...:argue:

[lostoffroad]

i can tap your box for you and then you could just buy the psc ram kit.

Thanks for the offer but I can tap it myself. Been too busy with work right now that I hardly have enough time to finish making my bumper/whinch plate.

[gotpower]

If I wasn't married I'd tap your box :)

Okay, so I decided not to go full hydraulic steering due to the fact that there maybe a few trails that I will be required to drive the jeep on the road. So I want to do hyd assist. Now this same forklift junk I have won't work. So my question is what size cylinder is the best to use for assist; bore, stroke? Dana 44 and Dana 60.

2" bore with 6" or 8" stroke, depending on length of arms on knuckles.

Usually 8" stroke is the ticket:)

And I will be able to tap my stock steering box and run a cylinder of that size without serious lag in the steering?

I looked through my records, and the best ram to use for trail and street is a:

1.5 bore / 6" stroke

If you want a little more power than use:

1.75 bore / 6" stroke

also use a smaller pully on the pump, gives more power at low RPM's

Todd...

The rig I just bought has full hydro with a load reactive valve... I'm a little lost on exaclty what determines the lock to lock aspect of the steering. Sounds like it has something to do with bore size and how much volume the pump is putting out????

Heres the thing; I'm about 5 turns lock to lock, which is gonna be a little slow for my style of driving... would like to get that down to under four maybe around 3.5. Is there a way to adjust it?

Thanks...

Here is a snap of the front; don't know if that helps in the answer... I think this is a "balanced" setup; if double rams = "balanced" which I think has an affect on teh load reaction working.

Search pirate for your specific box.

You will need to change the orbital steering valve to change the speed of lock to lock.

I need to know your steering ram size and I can get you the orbital to make it quicker.

Todd I'll shoot you a PM later today when I can get out there and figure out exactly what it has...
