Ben, first, I'm in my late fifties, currently disabled but still work a little on tractors. I currently serve as director/advisor to the technical college in my area in the diesel and ag mechanic's dept's. So on that, I was service manager at an IH/CaseIH dealership for fifteen years so, I do have a lot of experience in these. Your problem is not strange but, I need a lot more information first. Is the tractor making a howling noise? Does the hyd oil, if you run it into a bucket from the couplers foamy or a solid stream without any foam? Next, you said you replaced all the gaskets and o-rings on the SCV, right? What about the pump? I was reading your problems and got mixed information as the SCV regulates flows and pressures. The main thing I was wondering is it the rear hyd, "three point and aux hyd" or is all hyd, which is the steering brakes, etc? If you want to talk more, just email me your answers. I can help out on this but, need more info. to analyze. Thanks, and good luck. my email is bigjvetick@gmail.com if you want to contact direct.

Now lets take a look at some general maintenance tips that will keep our system operating to its fullest potential. The two biggest enemies to a hydraulic system are dirt and water.
