I have been trying to figure this noise out under the dash of my 4320. I bought it in May and it has 6200 hours on it. When I start it, it starts up fine, it will have a noise under the dash like lack of oil in the lines. The noise somewhat goes away with higher RPM's but I have never lost any hydraulic function, the steering always works as well as the remotes and three point. I checked the pressure at the remotes and it is right at 2000 psi. I have been researching it and I think the pressure is supposed to be higher like 2250 maybe? I have changed the hydraulic filter and cleaned the screen which was not dirty. The only thing I did do was to change the hydraulic pump connector bushings, the rubber ones up front because the old ones were shot, but I was reading a post last nite that said about timing the hydraulic pump and was wondering if thats what it could be but the details on timing it were unclear. Anyboby heard of this or know where I should start checking the get rid of this noise?
