Case 1030 Hydraulic Control Unit

I bought this tractor (Case 1030, dsl, ck, 8-speed draft o matic, dual hydraulics, clutch on floor) at an auction in Nov. 2008. It had a dead battery but otherwise it seemed alright. When will I ever learn? Got the tractor home (I pulled this tractor about 50 miles on my flatbed trailer up and down some steep hills, sometimes in granny gear with my old 250 PU. What an idiot!) and hooked it up to my 20' batwing mower and discovered that the pto didn't work and neither did the hydraulics. I changed the hydraulic filter. No change. I put in a rebuilt hydraulic pump. No change. I tested the batwing mower by hooking up my Case 430 to it, revving it up (the tractor not the mower)and observing that it raised the wings. I put new hydraulic hoses and couplers on the 1030. No change. I called a Case IH dealer, and he told me that a rebuilt hydraulic control unit is high $$$. So, I'm in neutral right now waiting for some manuals from Case New Holland Document Center. Is it possible to rebuild the hyd control unit in my back yard or is the only option to hock my first born and buy a rebuilt unit?
 
Hope this is not the problem,but. Does the pto turn without anything hooked to it? If it does most likely the clutch needs adjusted. The hydraulic may have a stuck valve. If the pto does not turn when engaged with nothing hooked to it there is a possibility that the drive shaft from the engine is broken or not in the tractor. I have seen them put together after a drive clutch replacement and the drive gear left off of the flywheel. Make sure you have power to the back
 
my guess is that if neither the pto or hydraulics work you have something mechanically failed inside the tractor, (stripped splines maybe) as the hyd pump is driven off off the shaft that runs the pto, the pto is mechanical and does not require hydraulic pressure to operate,2-way hoses get hooked side to side and not one side or the other
 
With the engine idling carefully and slowly crack the outlet pipe fitting on hydraulic pump loose, it should begin leaking oil out indicating the pump is turning. If it does not you could have a problem as Doug has mentioned. If it does pump oil out, there could be control valve or coupler issues. A pressure test would point you in the right direction. If the hyd pump is turning the PTO input is also turning indicating a mechanical problem, perhaps a simple clutch adjustment, but more than likely the PTO unit will need removal and inspection.

I worked on a neighbors 930ck once that had lost scv function, the stem (or whatever you call it)in the relief valve had broken off
 
I'm not sure where you are located, but I would be interested in buying it if you are frustrated to the point of getting rid of it.
 
Kinda hard to help with the problem if there is no feedback. Does the pto lever snap over center when pulled up or just loose feeling? Could be the brass collar has worn thru. If the pump is turning it will feel warm to the touch after running a few minutes.
 
A 1030 is like a 930. if you have an IT service manual you can fix anything on the tractor.

I assume You DO NOT have 3 PT either?

It sounds like a coupling problem inside the tractor since you dont have PTO.

Pulling the back plate off the tractor is not that big of a deal.

It will require a good breaker bar set and a floor jack and an over head hoist or engine crane.

If you decide to tackle the job I'm sure people here will help you through it.
 
I forgot to add with the tractor running place your hand on the hydraulic pump and see if you can feel the pump running. It should vibrate and whine slightly.

If not then the coupling at either the PTO end or Clutch end is stripped.

Just my 2cents
 
I don"t know that I can add any other suggestions, but sure would appreciate if you would tell us what you find out. We lost PTO and hydraulics on our 1070 this spring and it was a splined coupler that failed. Not a bad fix. Don
 
Thanks Don. It would be great if the problem turns out to be a simple fix! but knowing how my luck runs I have a feeling that it's not going to be. Stay tuned.
 
Thanks brokengun. Hey all the 2 cents add up! Keep it coming. I need all the help I can get and then some. If I don't get this tractor fixed soon (I'm 76), I'm going to be dead and gone and my daughters will just sell it as is and that would be a shame.
 
Casecollectorsc, thanks for your advice. I'm going out to the barn in the morning and check how the pump feels. Is the brass collar on the pto?
 
I live in Kentucky. Half of me tells me to get rid of it, and the other half says get it fixed. I have already spent a ton of (borrowed)$ on it!
 
Thanks Rod. Lots of good advice! I tried to take a pressure test but got no reading. Called in a mechanic and he got a reading of about 920. I asked him for advice and he said, "Get rid of the tractor before you spend any more $ on it" I asked him if he knew anything about Case tractors and he said,"No, but I'll take your blank check and start working on it" His name is Rogers and he is from Mt. Sterling, Ky.
 
Thanks dboll for all the good advice. Before this is all over, I think I'll know the rear end of this tractor pretty well.
 
hey just thinkin thanks for the great advice the pto turns very slowly with no load have been able 2 get it 2 stop with a 2x4 underneath it keep the advice coming i need every bit of it
 
Hello again. I have gone round and round a hundred times about this. The Case IH mechanic in Shelbyville, Ky. tells me one way, and the next mechanic tells me no they have to be hooked up the other way. Maybe thay's why I'm feeling a little squirrly now! To further confuse me the line on the batwing is one way flow with one line running to the wings which splits into two before it gets to the 2 cylinders. I had heard that the flow on this tractor is two way flow.
 
Just received a box of manuals from the Case New Holland Document Center. Guess I'll have to start reading now. I'm tempted to take the auxiliary control valve off the tractor and see if anything looks obviously wrong. My gut feeling is that the (high pressure) relief control valve is shot. I'm usually wrong about these things though. If it turns out to be the relief control valve, that may be the toughest thing in the auxiliary control valve to replace.
