Working on a 684 hydrolic whine noise. It sounds like its coming from the clutch housing but I know sound can travel through the housings. It changes pitch anytime I move the steering wheel, engage either remote or use the 3 point. All hydrolics work like they should. Pressure at the remotes is 2500#. So far I"ve changed the filter, pump and gear,(Aluminum pump housing by gears showed wear,heard worn gear could make noise) and pulled all valves out of the multiple control valve and inspected and cleaned. Nothing apeared to be bad. Noise sounds like a restriction somewhere. Did I miss something in a valve like the flow divider etc? Any sugjestions. My next steps were to change valves starting with the Flow Divider.
