Hello, I have a 2040 JD that started to make a chattering noise in the hydraulic when you lift the 3 point and also the steering and 3 point do not work properly. First off I drained the hydraulic oil, pulled out the suction screen and cleaned (wasn't dirty at all), replaced the filter and refilled the system with new hyd oil. I noticed that the oil was foamy like air in it from cavitation. I checked the lines and fittings and pulled all the relief valves out and inspected, cleaned and re-installed them(all good). I pulled the hyd pump off front of tactor. I dissassembled pump and inspected (looked good). I replaced shaft seal while out. Put pump back on tractor but still has problem. I still think there is an issue/leak on the suction side of the pump since the problem is both the 3 point lift and the steering and since both systems are seperate on the pressure side but share the suction side. Anyone have or seen this issue and have any ideas or answers to what the problem might be??
Thanks, Karl
