Case 2090 hydrolics problems

New to this forum but I'm having problems with my hydrolics on my 2090 case and wonderin if anybody would have any suggestions! The hydrolics work fine when cold but after using it for about 30 min or so they cut out like there's nothing there ! Rev it up and down a few times and they kick back in and when it does kick back in it's still got 2100 psi so I don't think it's the pump any suggestions thanks
 

That system is quite more complicated than our old system with different test hookups and procedures, If your system works well in every respect other than when it screws up I would suspect a compensator issue, there are others on here that know that system better than I, if an individual system was messing up I would suspect problems with sensor check orings but your system works well as long as it works and starts working again, hope 1370 checks in on this one!!
 
Repaired a number of them as well, I agree with you mEl sounds like in that area unless some one has been "working" on things, could be something simple someone installed or a modification that was done,, seen many things cause this best if you can get someone to look at it that has worked on them before, and a Case SM to go through the diagnosis may help narrow the search

Agreed CN, without something better than basics hydraulic systems knowledge you can get in over your head real quick.
We went out of ag not to long after the buyout of IH so been away from it a while. IIRC though the 88 series IH used the same or similar pump and compensator.
 
Trouble shooting that pressure flow compensating system without the test equipment can drive one crazy. And those on again, off again problems only make it tougher. If I
had to guess my thoughts agree with Mel's and Nutty's, compensator issue. The flow control piston in the pump can also stick causing almost no flow, seen that happen, but
have not run across a system that is on and off like yours. Hopefully someone will chime in and say I know what you need to do, Rod.
 
The first thing I would do is drain the trans. oil and pull out the pickup screen to make sure it is clean. Then I
would put in new Hytran and new Case filters. If that does not fix the problem Iwould try to find another 2090 or 2290
and start switching components one at time. Start with compensater valve andthen pump. Ifound the tests Are hard to do
and the results are not always accurate. It is quicker to move parts than to test Stan
 
Make sure your low pressure standby is not set too low at the compensator. If it is the hydraulics may not respond when you actuate a
control valve.

Thanks for all the replys I do have another 2090 case the same as this one so I could take parts of the good one to try on the bad one as for the low pressure stand by how do u set it or know if it's set to low thanks
 
If you have another 2290 it may be the easiest for you to just take the compensator off the good one and exchange it on the tractor that is
giving trouble. The low pressure standby is checked by disconnecting the load sense line at the pump. You cap the line. Then you can
check the pressure at the remotes. I do not have the specs in front of me but if I remember right it should be in the 325 to 350 range. This
needs to be correct before changing your high pressure standby.

Thanks for all the info I'll try a few things on it to see if it fixs it in the next couple days and I will report back if I find out what the problem is so it might help some one else in future! Also I'm new to this forum but how do I write messages without quoting someone eles message all I see is I have to click reply on some else's message
 
It sounds like a load check problem in the load sense system. If there is trash in any of the check valve the system stays on the standby pressure. That should be set a 210 PSI. Is it all
the remotes that don"t work or does one still work? Does three point work when this happens? The problem will be in the valve that still works. Chad

have 3 remotes and they all act the same when it messes up I don't have a 3 point hitch on it its a power shift model and everything for the power shift works great and steering and brakes work good to
 
Being all the valves do not work then the compensator would be where I would go next. That is easy to remove and check for sticking or contamination. One more question does it change if you
shift the powershift or if the PTO is on or off? I have seen a leak in these and it will steal all the oil so you have no hydraulics? Chad

no it doesn't seem to make a difference. It seems to act the same wheather it's on the baler or just lifting bales

eporting back that I found a broken wire on the load sencer repaired the wire feed cows with it and never acted up once where before it would have acted up 10 times for sure so I think I got the problem figered out thanks for all the comments and the help
 

hey I was just reading this old post and saw your response on what fixed your tractor. I have a 2090 that is doing the same thing. Where was this wire that you found broken?
