Got a strange question,,,, I am building a Hydrostatic steering system for my IH 460 puller, I got an entire steering system from a IH 403 combine, which is fully hydrostaic on the steering. Question is,,, how much hydralic line pressure, does this set up use? I have pictures so you can uderstand what I am doing,, but I need to find a pump that will handle the system. Maybe a Chevrolet?

The way I understand the concept of steerin' a pullin' tractor, it goes like this: Left brake = left turn; right brake = right turn, and the steerin' wheel is just somethin' for the driver to hold onto as he's sh*ttin' his pants while the front end comes up way too fast.

So...did I get it right?

LOL! That is why there is DEPENDS!!! HE HE!! Yeah, sometimes, the front is off the ground, and steer it with the brakes,, but, I gotta drive it up to the starting line. I like Allen's explanation!! That is the truth! Hopefuly, this does not break on me. In pulling, there is alot of cobbling for lite weight parts. Just dont use a JD part on the IH, so it dont break!! LOL!! Another reason i am doing this,, is because the parts that I am using,, comes from IH technology, 100% IH on this puller, no other colored parts on this one. I saved about 60+lbs with these parts VS the conventional rack and pinion, and steering rods. I just wanted to say thanks to this forum. I looked all through my books on the 403, and could not find any info on what I seeked, So, I asked the folks who knew IH!! Thank you all ya IH mechanics!! ChadS

Just a wild idea here and probably isn't really applicable, but, if you could spin it fast enough, why not mount your power steering pump out back and drive it off the pto shaft? I'm pretty sure tractor pullers go to great lengths to take weight off the front of tractors and get more weight on the rear.... We do this on our dirt track stock cars- the oil, powersteering, and fuel pumps are all driven off the back of the bellhousing in an attempt to put more weight on the rear wheels(ie-traction). Ok, go ahead and laugh! :)

Chads, I put a perkins Diesel motor into my 3/4 ford pick up. Had hyd steering pump built to fit motor. It started blowing hoses ,steering boxes, ( destroyed, at any where) and hydroboost brake unit. I went to Ford and they told me the pressure on steering box and hydro, was 1800-2000 lbs. Pump was delivering up to 10,000 lbs, and pump man sold me a inline pressure relief valve, and I adjusted to 1900 lbs and hve never had another problem with it. It steers good, and will stop to. This truck is a home built 6x6, F-250 10 wheeler, to pull my tractors with. Jack

Jack,
If you don't mind could you e-mail me, I would be interested in your perkins swap into a ford truck. I have thought about doing it in an older ford and would like to talk with someone that has done it. thanks Jake

I have no experience with it but if the steering cylinders are large there could be a problem with the flow rate delivered by a vehicle pump. Just something to keep in mind.

I was going to use the original hyd pump off the combine, it bolts on to the side of the timing cover on the engine. I cant do this, because I swapped the timing covers, from the combine, to the tractor. so, lost the place to mount the pump. I do have room for a auto power steering pump, on the engine, just curious if it would have enough pressure to run it properly. This tractor has no hydraulics on it whatsoever, the only hydraulics it will have is the steering. Thanks fellas!! I appreciate the info very much!! Same as the 706???? interesting,,,, ChadS

The 403 hydrostatic steering system is about the same as a tractor system, say a 706. I recall the steering pressure relief on a 706 is set in the 1200 to 1400 PSI range. Perhaps someone will post the exact figure before I get to the shop to look it up. That would be above most vehicle PS pump pressures, but a vehicle pump would probably work just fine (unless it needs to steer with A LOT of weight on the front wheels). It may be possible to set the relief pressure up a bit on a vehicle pump, also, for this kind of application.

I was wondering the same thing... Half the time their front ends aren't even on the ground!

Dick,

Yes, but in the majority of instances, those hot-rodded, cobbled up old heifers will break down half way down the track. Let's face it, longevity just is not their long suit.

So, at that point, it is much easier on the embarrassed owner to quickly turn and steer out of sight as soon as is humanly possible.

This is why we need the power steering. :>)
