Nothing special - JFYI. . This is an OTS Magister 2 x 14 cylinder and seems to be a perfect match for my L3901. Does require 1 x 3/4 reducing bushings at both ends. Expect it will also work on the other L01s. My first experience with a hydraulic top link and I am already spoiled. Dan

Everything as normal except your comment on the lowering speed valve. You start by saying valve is open and then you say it won't lower unless you open it. That is contradictory. Was the test run with the lowering speed valve open or closed? It should be run with the valve open. Need a much...

Real simple test. Raise the 3pt conyrol lever in stages,: 1/4 up and stop = what happens? 1/2 up and stop - what happens? 3/4 up and stop - what happens?

The stripped thread can be repaired with a thread repair insert (AKA Helicoil). It is utter fsntasy to characterize that repair as a modificstion that would void any warranty. The original threads are standard metric screw threads and never functioned as a liquid tight seal. A sealing washer...

Then go for it. Personally I would visually verify the spool is sticking BEFORE taking the valve apart. Dan

That does not look the sane as tje first video. In the first video it seemed like the 3pt struggled to raise and in this one ot looks smooth. I cant see what the linkage is doing but it sure seems like the feedback is out of adjustment snd when the 3pt gets too high at the top something in the...

And it behaved the same at all settings? If the position control linkage is connected and working the 3pt should have completely stopped lifting al one extreme. Dan

A really easy test is to set the feedback adjustment to its max and min. If the problem is something thst can be adjusted out one of those two settings will do it. I also see draft control was an option on these tractors. If you have draft control the picture chages big time. Dan

OK - here we go. This diagram should be your current loader and backhoe plumbing. The loader valve is supplied from the hydraulic outlet block under the right side footboard and the backhoe is fed from the power beyond port on the loader valve. I have drawn the loader valve showing the...

I pretty much agree its position control related. But the 3pt is behaving very badly from top to bottom which leads me to think its more than a couple turns on an adjusting nut. A video showing the behavior of the feedback linkage as the 3pt is fully raused, bouncing at top, and then lowered...

Hey questions are why we are here!! People that dont/wont ask questions either dont learn or they learn the hard way. I will give you the exact plumbing hookup for your tractor but I need to make sure I know what you have. Its an l4901 with BH92 backhoe? Do you have any other rear remote...

The loader valve appears to be plumbed using tank for 3pt power beyond. If thats the case how can the loader work when the 3pt seems to be deadheaded. I had trouble seeing just how well the loader actually worked and a better demo of it might be helpful. We can see that when the 3pt gets to...

Its quite clear that simething is blocking the pump circuit. The bouncing at the top seems to be the position control valve either trying to lower the arms or relieve excess pressure. I say that because it stops bouncing when you close the lowering speed valve which cuts off all reverse flow...

I will put you out of your misery and make the decision for you. Trade the tractor. :D Dan

I had anothet look at the parts diagram. There are no ball bearings in the joystick linkage. I think you are talking about the detents in the valve itself. My advice is dont go there unless you have to. Exhaust other options first. Dan
