Jim, as Clooney said, if you don't have a manual, you will have to be careful with that unit. I don't know how familar you are with this system, but here are some basics:
1- Make sure the system is full of oil. It must run out with the petcock open, the one on the right rear of the rockshaft housing.
2- Deere reccomends non-det. 10w motor oil. 20w or even 30w will work, just may cause more viberation in the lines.
3- To test the pump, if you don't have access to a high pressure gage (over 1000 lbs.) You can loosen the smaller line at the lift housing, then spin the engine over, it should squirt a good stream of oil. If not, something is wrong with the pump or lines or fittings. This is a messy way to test, but at least it will tell you if the pump is working.
4- If all the above is ok, you may have to go into the lift unit. Get a manual for this. The service manual is SM2013 the parts manual is PC862 Both these manuals are invaluable if you plan on keeping or working on the tractor.
5- If you do have to go into the unit, the piston rings and other seals and o-rings are pretty easy to replace. Just don't mess with the relief valve, unless you are expierenced with this system.
6- Post back on your findings, we can work you through a re-build, if it is necessary.
