So is it low on the backhoe or the loader? Does the steering seam to be affected too? Have you checked the pressure when it was hot? The filter is for sure the best place to start looking. Because if it is starved for oil it will have low pressure. There is a relief valve in the loader inlet section. There is a test port on the left side in the pressure line coming from the pump in the frame about even with the fan blade I think. You can go on line to most Case Construction dealers to look at parts books.
