If you have a NX series I'm curious of those who have noticed elevated hydraulic heat levels - do you or don't you have the factory third function installed on your tractor?
My theory is the factory third function, at least the one that was installed on mine, is a major contributor to the hydraulic heat that I'm seeing. The flow goes from pump to loader valve manifold, then to third function manifold, then to rear remotes, three point and finally returns to tank.
The factory kit installed on mine uses reducer fittings along with a much smaller set of hoses to connect the third function valve than the hoses / lines that go from the pump to the loader valve - loader valve to rear remote.
Since that circuit gets a constant flow of the bulk of the fluid the bulk of the fluid is constantly being heated.
I'm going to work on this some more with my infrared thermometer and measuring pressure at the loader valves versus the rear and report back.
