I need a little help with the hydrolic valve on my 4420. This would be at the valve body under the cab where you connect the hose for reel lift when useing the grain head. I needed to take the fitting out on this connection in order to get the elbow next to it out (threads got damaged and needed to replace it, was fixing the steel line). Thought it would be simple, but a small restrictor orfice fell out. It looks like a hex head off a bolt with a groove cut across one side(top or bottom) and a very small hole in center. I need to find out which way it goes back in - groove up or groove down(next to fitting/coupler). I looked on JD Parts but they don't show which way it goes. Any help would be appreciated. (This also gets connected to the variable speed feederhouse cylinder when using the corn head.)
