    1972 JD 2030 hydraulic help?

    Working on my neighbors 1972 JD 2030 68HP diesel tractor for a hydraulic leak. The tractor has a front end loader which is connected under the tractor at the selector control valve for what looks to be the rockshaft control on the right side of the operators seat. I disconnected the hoses to be front end loader, but the tractor is still leaking at what appears to be the selector control valve. Does anyone have a hydraulic schematic for this tractor or parts number list. I don't know if he has a service manual or not. Thank you!!!

    Sounds as if you're correct that the scv is leaking. You can view parts schematics for free at JDparts.com. Photo is of seal kit PN AR85271

    My 2030 has two factory rear SCVs. When I had a leak it was the O-ring(s) between the two valves. Good luck
