i don't know much history on this tractor but I've had it 5 years and it has always had "high" oil pressure. that hasn't changed.
I have no idea how accurate the new gauge is, nor the original 3-zone indicator. i suspect they are accurate to at least 5% which is fine for this application i would think.
i wonder if the oil pressure relief valve setting or the spring in the relief assembly may be worn or need adjustment.
i suppose if everyone says oil psi on the high side isn't the worse thing that could happen i should not mess with the setting.
i should add the head gasket does leak some oil (not enough to measure, but easy to see and would not be acceptable for a show tractor)
the head was worked on before i owned the tractor and believe the work was done diligently and correctly, but i don't really know.
maybe the head work wasn't great or at higher operating pressure one gets some leakage even with reasonable care when head is re-attached overhaul.
