Help! 1030 ps converted to flow divider. No good

Got a 1030 western and the ps pulleys were worn out. Couldnt keep a new belt on very long at all. But when it was on it steered fast and easy. Rather than put all 3 pulleys on we added a flow divider at the direction of a reputable case shop. They had done several and said it was the way to go. So i got it all done and it steers very very slow. Crank as hard as you want it just makes your arm sore and really not much faster. The valve was sent back to prince to verify it was good. 2gpm and 1100 psi relief. I verified this after reinstalling it. The flow is 2 gpm in and out of the steering box with or without cranking the wheel. It makes 1100 psi relief pressure with wheel held at either end. Makes 1100 dead ended too. It has 303 fluid. Has 1900 psi relief pressure at the couplers. Took the control valve apart to clean and inspect and replaced the orings on the ports inside the torque motor. Still a pos. Its not much better with the front end off the ground. On the ground it makes no difference if sitting or moving. it was better with the original pump as long as the belt would hold. So what if any help do you guys have? I have no restrictions and 1100 psi and 2gpm available. The guys tell me thats more than the tractor had when new. Seems to me it needs more flow but i saw myself in the online parts manual original pump had 1.5 gpm at 700 rpm at 700 psi with 950-1100 relief setting. I do hear the relief valve squal at times when im trying to reign this horse now. Ready to burn it down. Help ?

I may be mistaken, but I think the Case belt driven pumps were in the range of 4-6gpm, not 2gpm. just my nickles worth of recolection.

I looked in the service manuals, but cannot find a flow spec, only press. 2GPM doesn't sound right.

Its in the 830 parts manual. One of the 830 pumps listed is the same part number as the 1030 pump and the specs are in the 830 parts book.
That being said a man just stopped in here and in course of conversation it was learned he has an engineering degree! So i threw this at him. Showed hom the manuals and the tractor and he thinks since i now have 11 ft hose feeding the steering box the dynamics of the system are way different than original and may require more velocity or gpm to do the same job as before. Longer larger hose necked down to the original steel line that was cut off the original case ps line/hose. Thoughts? So far he and i say its not enough flow to feed it properly to make it easy and FAST like it used to be

Ok here's two cents from another guy with an engineering degree, while I agree with him that the length of your hose can affect your flow etc I do not believe that that is the root of your problem. I looked at the parts book and as you said the original pumps were rated at 1.5 gpm and 700psi at 700 rpm. That being said they put out significantly more volume as the RPMS of the engine increased. The valve that you installed is set to 1100 psi and 2gpm at all times meaning as the rpms increase you get no increase in flow. Did it turn easily with the old pump at 700 rpms? If not I think your going to increase the flow. As I said thats just my 2 cents.

It was a heckuva lot easier than it is now. As i recall it may have gotten a little easier with extra rpm but the case pumps have a flow limiter of some kind. Problem id we dont know the full potential of one.
But yes it was easier before in every scenario except when the belt slipped. Good belt and it was awesome. Just like my 730 and 830.

I just had another thought or concern. If I read your post correctly, the flow divider always maintains 1100PSI on the circuit. It sounds to me that the tractor Hyd. pump will never be at rest, thereby always robbing power & shortening pump life.

Not that it does but it is capable of it. The 2gpm is constant however regardless of pressure in the system. So 2gpm is the maximum allowed to the steering now as well as the 1100 psi. Both could be maintained constantly as the tractor hydraulic pump exceeds those numbers by a great deal.
What i would really like to know is what was the total possible flow from an original ps pump? Im thinking i would need slightly more to do the same job because of the 11' 1/2" hose supplying the steering box vs the original 2' 3/8" dia hose. Anybody able to come up with a max flow spec on the old case pump?

I am not that familiar with that model case, but I have never seen a power steering system on a tractor with only 2 gpm flow. Normally 3 to 4. If it is powerful but slow, it is lack of flow. If it lacks power and also slow it would be resistance to movement, but you kind of ruled that out by raising front end. I would install a gauge in the line after the flow divider to see how much pressure it takes to move the wheels and then a gauge before flow divider to see what pressure of pump is with steering in neutral . Should only be about 2 to 3 hundred psi to overcome pressure balance spring in flow divider.

Going to switch the 2gpm flow divider for an adjustable unit and add a seperate relief valve. We will then adjust the flow to get the steering acting right with proper relief pressure and measure the flow to see how it ends up. Probably be next week before the parts arrive.
