Case 2290 Hydraulic Problems

Marston2 · Jan 21, 2012

I have a case 2290 and am having problems with the hydraulics. When i pull the lever back in the cab, it will raise the implement an inch or so, and then stops. I have to keep rocking the lever back and forth to fully raise the implement and it takes about 5 minutes to do so. I have noticed that when i step on the clutch for several seconds, then pull the lever back as i am letting out on the clutch, it raises the implement a little bit better. I recently changed a roll pin in the transmission and found quite a bit of shavings in the bottom of the transmission. I am thinking that the gears are gone in the gear and piston pump.

Does this sound like a problem with the charging pump or the gear and piston pump? Or could it be something else? Thanks!

I’m assuming since you didn’t mention problems driving it that it does move itself around ok? If it does the pump “should” be alright. I’m probably totally wrong on this but since this tractor has the variable-displacement axial piston pump in it, I’m thinking maybe a problem with the load-sense valve/lines/related parts etc? Someone please tell me if I’m on the right track!

Yes, It does drive around just fine.

Yes, It does drive around just fine. I put it away for the winter and everything was in working order. When I pulled it out in the spring, the hydraulics were not working properly.

You did not mention if this is the three point hitch or the remote hydraulics. If it is the remotes check the quick couplings for a broken or weak spring.

This is for the remotes. The 3 point hitch moves, but a bit slowly.

Have had some compatability problems with Pioneer and some other ends locking off in the ISO couplers, you may try that as a possibility, they act exactly as you describe. Put a 5000 lb gage in the remote and see what the system pressure is. mEl

I put a gauge in the remote and the pressure was reading 800-1200 PSI. It should be much higher than this, shouldn't it?

Yes thats low, there is a test procedure to test that PFC type system you really need a service manual. Someone else may have some input on this as well but you may have a failed compensator valve on the pump, but it bears checking out to be sure, not just throwing money at it. mEl

The PFC ststem uses a series of sensor check valves and something as simple as a blown sensor check oring can put the system down mEl

Looking at the hydraulic pump circuit diagram from my dealer's online parts catalogue, i notice that there is a pressure switch - filter pressure sending on a line that runs from the pump to the oil filter housing. If this swich were not receiving power, could this possibly be a cause of the problem? If it helps to look at the diagrams i am looking at, let me know and i will tell you how to get them. Thanks.

you say 800-1200 psi is that at all the remotes?

That should be the filter indicator sender and if you ground it the trans filter lite should come on.

The above poster has a good question, did you check all the remotes or just the problem one, there is a reason for this as sensor check problems can be isolated by checking all the couplers and looking for strong ones or weak ones. If all are the same the sensor system in the remote valve is probably ok. As I stated, there must be a basic understanding of how it works to help you through it. mEl
