hydraulic Question

[mtwap]

I have a cub cadet 7205 with FEL. The loader works fine no problems but if I raze the 3 point (even with nothing on it) the Hyd scream. (Engine RPM drop 50-100 Rpm) It sounds like its coming from loader control valve . All the lines are right; I just replaced the filters and oil. It has done this since I got the tractor. Any Ideas? Thanks

Is this going on with the three-point lever all the way at the top?

No its dose it all the way up. It lifts ok but I can tell with the drop in rpm that it must be loading up the pump. I need to put a gauge on it but haven’t had a chance. I was also going to disconnect the HYD’s on the loader and see if it still doses it.

Sounds to me like the TPH lever is not adjusted right and not opening the valve all the way. Is the lever a little loose on the shaft?

Well I unhooked the HYD for the FEL and the squeal went away so it must be a problem with the FEL control valve. I picked up a pressure gauge I’m going to try putting it in line before and then after the control valve and see how fast or slow it recovers , I know it’s not as good as a flow meter but for the cost of one of them I can just about replace the Valve.
