IH 574 hydraulic panic

Posted by Wayne M Kittler on September 14, 2004 at 19:49:45 from (24.194.176.223):

My IH574 has full use of all hydraulics- ps, 3 pt , pto and remotes until the hydraulic fluid hits a certain temperature. Then all hydraulic systems fail - ps first, then remotes, 3 pt and then pto, in short order. I would suspect the pump or safety valve except for the temperature condition. When the fluid cools to the correct temperature, every system works again but only until a certain temperature is reached. This is an odd situation. Hydraulic oil viscosity would not change so much that it all escapes through the pump or relief, would it? All help appreciated as I need to use the tractor for highway transport and can not seize up on the road.
