Kioti nx6010 loader backhoe
I have 132 Hours on my machine, and a few months back I was using the backhoe and I started to get a high patch whining at 2000RPM. As soon as you move the loader stick it stops but comes back when you let it go. At this point I have disconnected all the lines reconnected everything made sure there was no leaks check the fluid level and the dealer sent me a new loader Val that I replaced and its still doing it. Anybody have any other ideas?

Certainly sounds like a loader valve issue. I wonder if there are any adjustments on the valve, to center the reliefs when the lever is neutral?

Im not sure. They sent me a brand new valve that I put on but it's still doing it

Could it be the relief valve? Like because some downstream hydraulic control like rear remotes is dead headed?
Sounds reasonable. Do you have a video of when it's making the sound?
