TR320 jerky controls.

[MillerModSaws]

Good evening. I have recently purchased a 2011 TR320 with 1400 hours. Off a dealer. Long story short. It's so jerky I can't hardly use it. If you adjust the sensitivity running in iso. The loader adjusts. The drive dosnt. If you run it in H. It turns to the right. The dealer is telling me nothing is wrong. I run bobcat and cat skid loaders. Quite a bit. And I can't run this one. There now wanting to change the orfices in the pump. Saying that was a case fix. I think the left controller is messed up. But please any advice would be appreciated.

Mechanical or EH controls?

EH

I know the mechanical control pump has orifices. I do not believe the EH pump does. Maybe the hydro was taken apart and put back together with the valve plates in wrong. They can be indexed in two locations in the EH pump.
