Hi,
I have a TC25D with a 7308 fel and backhoe using the NH hydraulic kit in which you switch the hoses and disable the 3pt arms when connecting to the bh. My question is this. What governs the pressure to the bh valve block? Is it the relieve valve on the fel or some internal relief inside the tractor? It would be really nice if we here at TBN could get a hold of New Hollands hydraulic schematic for our tractors. Any factory guys listening???
At any rate, maybe someone out there knows the answer to my question.
One more thing, what happens to the oil in the fel valve when the fel relief trips? Does it go through the power beyond port back to the manifold on the side of the engine or is there another line (one of the steel ones) that the valve dumps the oil to to return to sump?
