Case 2390 hydraulic fluid pick

[Ron Bailey]

My 2390 hydraulic fluid/pump losses pressure when going forward up a hill just slightly. I checked the fluid and its little over the full mark. Is there maybe a pick tube that has come loose? Any thoughts /pictures?

1st thing is you need to be using a high quality TRANSMISSION - HYDRAULIC OIL as opposed to a simple hydraulic fluid. A CASE Dealer would supply you with Hy-Tran, but there are other good choices also. It sounds like you could be low on oil. Don't rely on the dipstick level when the engine is not running. Start the engine and let it run a minute, then check while running.
