My 2014 NX4510HST has developed a significant hydraulic leak at the inlet port of the joystick valve, where the fluid from the primary hydraulic pump enters the valve body.
See the red arrow in the two pics I've attached. One view is from the right side of the valve, angling upward; the other is from below.
I can get a big wrench on the fitting, and it is not at all loose at the point of the leak, unfortunately. I was hoping the fix might be that easy. :no: For that matter, I don't know if the fitting has NPT threads or uses a gasket at that joint. Nor do I know what is involved in removing and re-seating or replacing it, if that is indeed the problem. Anyone know if I'd have to drain most of the HST oil from the system first? I'm guessing yes, but hopefully not, as the fluid was just changed by my dealer recently during service.
Because access is so tight, I'm inclined to just bite the bullet and have the dealer pick the tractor up so my excellent tech can take care of this. I'll talk with them about this on Monday and send them the pics. But it's a 95-mile haul each way, so in the meantime I wanted to tap the wisdom here.
