1570 case tractor

[Anonymous-0]

Al.e here again another problem with me tractor got a loader on it and about a week ago I changed hydroulic filters and everything work fine. Now today I started it and let it warm up started to feed cows and loader barely goes up and got to rive engine use to be able to lift front of tractor off the ground now can't. Tramission gauge will go to the lift into red when trying to lift or but pressure down on loader (In need of Help).

Tried hooking hydrulics up in back to see if lifts slow too. could it be the screen.

im having the same problem.i looked in the manual and traced the hydraulic system.i found the orings were gone off of the hydraulic remote valve relief valve.the valve is behind the right rear tire.the relief valve is on top of the remote valve.takes a 1 1/4 wrench to loosen the plug.i just finished mine tonight and will let you know results tomorrow.clint

With the tractor idling, 4 sp in nuetral try raising in loader in R 1 2 3 on the powershift. If it raises at the same speed or not at all in all shifts replace oring in relief valve as Clint has mentioned. If it raises good in a speed and not others you have a powershift leak issue. Is your hyd filter pressure OK? Rod.

Rod don't really understand what you are saying in 4th speed. I do not use the back remotes for my loader I got 3 spool in the cab and hook to one of the pressure lines below, does that releif valve still matter.Al.

What I was saying is with the 4 speed shifter in nuetral, and yes if you got the valve plugged in to a rear remote the relief valve is controlling the hyd pressure unless that 3 spool valve has its own relief and some do, but test it as I explained. Rod.

It finnaly dawn on me what you were saying and did the samething slow and I do not have the loader hydaulics plug into the rear remotes. I come off the side off the tractor on one off the high presure lines the one that faces told the engine. but why is my back remotes slow too.

I would have to see how that loader valve is plumbed in before I can guess whats going on. If you could plug a implement into the remotes and try raising it in all the different shifts that would be helpful. Rod.
