Case tractor help needed.

[Swamp Donkey]

I am in the middle of haying season, and I beleive my hydraulic system is giving me some greif. The tractor is around a 1965-68 Case 1030. What is happening is when I try to lift the end gate on our baler, it can barely do it. Then it (the hydraulic pump possibly) starts making a clicking sound and won't go any further. Now here is where we are at. I believe we have enough hydraulic fluid in there. It is about 1/2 way up the dipstick. I may add more to see if that fixes it.



It only started doing this when we hooked the tractor up to the baler... ... ...





One more thing you should know. We blew a hose earlier on and I had to add hydraulic fluid. It was still a little low and did not want to go to town so I added 12 quarts of amsoil ATF. Could this be my problem?



Any ideas would be greatly appreciated.



How many gallons of thf will it take if I must replace it?

Since yer an experienced agrarian, I'll assume you ha the revs up high enough.

Is ATF reccommended for that application, or should it be a different hydraulic fluid?

First thing I'd look at is the pressure to see if it is up where it belongs. If not, it could be the regulator or the pump; I'd check the regulator first.

I wouldn't have used the Amsoil but doubt if that's your problem. Sounds more like an internal leak. Not sure on the 1030 but if the hyd fill cap is on the back of the tractor with the tractor running use a maglite (or other small flashlight) and look deep inside the fill hole. If you see "steam" in there you have a leak. Usually the repair only involves an o-ring but it can be way down in there, many parts to remove to get at it. That series of Case takes about 9-12 gallons of hyd fluid.

I might be able to help

Swamp Doneky,



I am glad to see there is someone else out there using the old Case iron like I am. I just put a 1030 hydraulic pump on my 400 this winter and now am running 2050 psi with it. It is wonderful. Anyway to help you with your problem. First off, I would not be worried at all about the Amsoil except for the cost. Those hydraulic systems were originally designed for Type A ATF. I usually run HyTran or the equivalent in my old Cases. If you have a pressure guage the first thing I would check is the pressure at the remotes. It sounds like you might have a relief valve spring that is broken. They are only about $12 US if you have to get one. Do the levers and the detents feel normal? There is also a chance that the "unloader" is stuck. THis lets youretract a hydrualic cylinder by bleeding off the pressure in the pump head. If you could give me a really detailed description of what is going on, I might be able to help you more. I would drain the oil out and look at it and the hydrualic filter to make sure the pump isn't breaking down internally (not real likely). I hope that has helped you out a bit. Let me know what you find out.

I just reread your problems again and just thought of something else. Try reversing your hydraulic lines and see if that fixes it. SOme of the cylinders only work well with the lines in a certain order. This would be the simplest remedy.

When my tractor acted up (pretty similar situation on my Farmall) I found out there was a filter in the hydraulic system that I didn't know existed. That seemed to fix the problems. Thought I'd throw that out.....

Filter... .....





Where is it?????? Yikes I have had the tractor for about 6 years and never seen or changed it. Oil and fuel filters are easy. I might try switching around the lines as well. Although we have them marked well and we ran it that way all last season.



Thanks for your help guys.

My filter is inside the gear case on the right side. The cover plate is sort of oblong and has 6 or 8 bolts holding it on. Of course yours may be different. (mine's a '62 Farmall 504)

Atta boy guys ... especially you Case5000D... .





edit: SwampDonkey thought that filter was for runnin his coffee fixins through ... didn't ya. . huh???

The hydraulic filter on my 830 is on the left side for the tractor underneath the platform and I believe just ahead and above the axle housing. It is a spin on filter. Mine is a 1967 model. Some earlier models had a cartridge that was under a cover in about the same position. Not sure if a 1030 would be similar or not. My dad has a 970 case that is very similar to my 830, but he has a 1070 thats quite different.

When you say that there is a "clicking" it makes me wonder. Is there anything else on this tractor that is powered by this pump? The reason that I ask is I'm trying to verify that the shaft splines are not sheared off of the pump or the drive. We had a 590 backhoe that would do this about once a year.



Just a thought,

Mike

Power steering (on mine) is also on the same system

More Thoughts

Swamp Donkey,



I did some more thinking while laying in bed last night. The 1030 pump I had would have had a cartridge type of filter. The filter would have been located inside the sump housing near the pump. All of the filters on the older Cases are held on with 3 3/8" bolts. If you are lucky, your filter will be a newer spin on style.



Also, which hydrualic line blew? Did you take an elbow off the pump? If you did take an elbow off, take it back apart and check to make sure you have a check ball, spring and 1/4" X 1. 5" steel rod. If any of these are missing, you will not be able to lift anything, or if you do it will fall back down. That is about all I can think of right now.
