Question. We have aquired a DPX1 that has had the sluice gates removed and water lines attached to the original gate operating rods holes that go into the vane housing. The rod holes have been tapped. The other ends of the two hoses did not come attached to anything but we understand that this was a mod for controling the load. Does anyone know how this was achieved? We'r scratching our heads!!!! The original inlet and outlet are still there.
