Three point valve broken!!!

well, maybe not new. I bought a used kubota because I didn't want emissions.

I'll keep the old yanmar until she dies

You may not live that long.

Aaron says he still thinks it’s something to do with the linkage on mine.
I don’t know what else to try though on the linkage. If I set it any “looser” the 3pt won’t stay up at all, again as if there is not a neutral position present at all.

Going back and watching your last video again I notice your lift does not begin to come up until your handle is nearly all the way up. I believe the lift should start to rise much quicker. Anything there to be adjusted that would make that happen?

you may be onto something. Mine comes up after an inch of movement on the 3pt lever, its very small the amount it goes up but its incremental to handle movement, there is no dead space in the range of movement of it.

I’m not 100%, but I believe there are 2 nuts on the lever shaft that if loosened may allow it to be rotated forward some. This theoretically would allow it to rise earlier in its travel it seems. I was looking at that Sunday wondering the same thing.

I was thinking about it this weekend while I was at my farm...or was it last? I was going to take some close pics of the linkages on mine so you can see how it's set up. Id go take some now but that's 3 hours from me. I will see if there any I took in the valve swap that will do you any good and may happen to capture the linkages.

I don't understand the problem but it seems to me if both the new loader valve and the new 3-point control are blowing out seals then there's an overpressure problem somewhere. Maybe a sump return that is sealed in some control positions, when it shouldn't be?

I believe his loader valve leak is because of back pressure when the 3 point is maxed out. That is the main reason for power beyond. However, many loader valve deal with it ok, evidently this one doesn't.
