560 IH hydraulics

Ed Dibling · May 28, 2010

I need some help with the hyd. on my 560. I have power to the front end loader for about 1 min.( enough power to lift the front of the tractor off the ground) then I have very limited power( barley enough to lift a 500lb round bale). I have hooked up a pressure gauge right off the side of the pump housing and have about 1400psi. I have this pressure only when the valves are moved but have the same psi when i have power and when i have limited power.
I have isolated all cylinder (one at a time) to make sure there is no blowing through. Same results when this happens.
Any ideas??

If you can maintain that 1400 psi at the pump when trying to lift the bale that would indicate the fluid is blocked some where. Most likely place is a quick coupler return male coupler. If you have 7/8th straight o-ring type hose ends you could take couplers off and hook direct into outlets to check. Some of them old couplers used on the 560 screwed apart so you could hook under pressure and sometimes they will back out a ways and block flow.

I didn't mention that in my post but all the quick couplers have also been replaced along with the hyd. filter and the oil.
