L4701 loader hydraulic issue curl down malfunction
Two lift functions work flawlessly and curl up works fine but curl down only moves a few inches and stops. I switched the blue and red hoses at the outputs of the control unit and the failure moves from the curl down to the curl up function. It appears that the issue is with the controller not the lines and cylinders on the loader past the controller. Also whichever line is hooked to the red/downcurl output ends up locking up the little ball valve in the quick connect hose. Can anyone confirm that my logic is correct that I have an issue with the curl down controller valve? Or maybe an over pressure valve in the controller?
