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?
