I have a NH 1720 I bought used from the dealer. I had a set of rear remotes installed. It has a 7308 loader on it with joystick control. Owned it for a bit over a year, 250 hours or so I put on it, 700 total. When I operate the rear remote, it has developed a sudden leak. It leaks on the black nut/stud on the loader hydraulic joystick controler. This is the little (hollow) stud under the rubber boot & metal sheld - where the joystick controls are. I believe this to be the pressure control for the loader? I have not tampered with this, nor does it look tampered with by previous owners. Anyhow, oil drips out the hollow center when I max out the rear remote lever. It does not appear to do so, or as much, when I operate the loader controls themselves. It does not leak at all when the I'm not operating any hysraulics. (However, we are in a tornado warning & it got real dark, so I had to park in the shed - need to check more/ better tomorrow.) Any ideas what is causing this drip? --->Paul
Is the hollow stud milled for an Allen key? I expecxt you're right and that is the release valve. They're all a little different but I would think it has replacable seals.
