IH 1086 hydraulic issues

[daynee]

went to go use my huchmaster disk today and my hydraulics wouldn't lift the disk unless I was going at full RPM which was about 2400 ,so then I hooked up the disk to my case 1030 lifts it on idle no problem , I just changed the filter on it and and put the THF over the full mark on the dip stick still has this same problem. I just got the tractor this spring has about 3800hours year is 1977 my friend was telling me it might be the pressure release valve or????

also were is the PRV located on the tractor ?

Thank you
dayne

The relief valve is located under the seat suspension. The valve screws into the seat support on the right side. I think it take a 1 1/16" socket. Also check the o-ring and back-up ring in the bore.

Did you not notice he is working on an 86 series?

The pilot relief valve valve is below the fuel tank, in the priority valve, easily accessible from the rear of the tractor.
