I am working on a JD 2020 with a hydraulic issue. The loader and 3-point have chatter in them and after 3 or so lifts there hydraulic system will no longer lift the loader. Wait a few minutes and you can get a few more lift, and so on, and so on. The tractor I believe is a 1966 Type T5H3C; SN 018900T with a JD146 loader. It has 4204 hours on it.
I have drained the fluid and checked the filter and the inlet screen. Both have a reasonable amount of particulate. I have inspected the suction lines to the main hydraulic pump and I cannot find any cracks in them, as I have heard that this is a common problem.
I am waiting for John Deere fluid and a filter to be delivered tonight. I plan to reassemble tomorrow and test the system.
I have a few questions in advance in case I have more problems.
1. If I need to get a service manual for this tractor, is the I+T manual an acceptable manual, or should I splurge and purchase the factory manual?
2. Are there any inlet screens or filters that I should be looking for before I reassemble?
3. Am I correct that the transmission pump supplies the fluid to the main pump at the front of the engine through 2 suction lines? One line goes from the transmission sump to the main pump, and the other goes from the transmission sump to the cooler adjacent to the radiator and then to the gravity feed hydraulic tank then to the main pump.
If things don't go well tomorrow, I am sure that I will have more questions to follow.
Thanks in advance for your help.
