Loader issue La525 tilt

[Moosebuddy]

Since you seem to know how to hook up and disconnect hydraulic lines well…

As I understand it you have a function (lift) that works and one that does not work (curl). So have you tried to move the hoses from lift to curl and also curl to lift (swap the four lines) and see what happens then? If it is the valve curl should work but lift won’t. If it is the curl circuit then it won’t work but lift should.

I think that is all correct but think it through and see what you think about that before you do it.

Yes you are correct the boom goes up and down with the curl doesn't work, it just suddenly stopped out of the blue, I haven't changed anything to it in the last 6 years other than change the quick connect five years ago, I'll have to try that I have not tried that yet, it just have a couple days ago and I got almost a month till I have to move hay again so I just started fooling with it thanks.

Yes there's a 3rd circuit with an electric button on lever it for a front grapple things like that, 2 solenoids, the picture of the matching thumb or finger coincide where each hose is on each item. 2 thumb picture, 1 thumb wraps around hose below orange marked hose, 2 baby finger picture 2 point finer picture , all of this was on the tractor when I bought it 6 years ago none of it's been changed, I haven't put anything new on it change anything done anything it just quit tilt part, all three hoses attached to the the valve body one on one side one on the other side and one in the middle on top were the lever is.
If any of what I just said makes sense thanks..

Sorry, don't follow. Does the line from the T port, lower right, on the hydraulic block go directly to the loader valve, or does it connect to the third function valve?

OK, were you using this and it stopped working, or did it work, then sat unused for a while, and wouldn't work when you recently tried it?

Do you have anything attached to the third function? If so, does it work? If not, is it possible to connect something to try it.

I haven't read through all of the posts.
If there is fluid going to the cylinder lines, then broken cylinder.
If no fluid to the cylinder lines, then broken linkage or spool valve.

Broken piston rod is a possibility. But if so, his boom wouldn't stall when he tries both simultaneously (assuming he tried both directions).

Curl and dump are different functions. Which do or do not work?

Have you checked the joystick linkage as I suggested? That strikes me as the most likely explanation for a sudden failure.

1. In float it still doesn't work
2. Not sure what exactly you wanted so I took pictures of everything
3.no kinks no bends nothing pinched that I can see
4. When I raise the boom and try the tilt the boom stops dead

That tells me the "tilt" circuit is blocked. This thread has gone way off the rails.

KISS. Disconnect BOTH bucket hoses at the hard lines, put them in a clean container, and repeat the simultaneous boom and tilt test. And in the future please say curl and dump not tilt as appropriate. The two functions operate differently.
