JD 301A s/a 1020. How to test hydraulic pump

[Tx Jim]

Thanks very much for the tip. Will check the serial # tonight.

If you have a 301A then there should be no problem BUT since you put 1020 in your thread title I thought I better clarify before someone else damaged their open center power steering pump.

Problem solved!
Once I connected a pressure gauge to the power steering line I found the pressure was around 900 psi, far below the recommended 1800psi. I adjusted a bolt at the bottom of the main pump. Truth be told I removed it, inspected it, and put it back in and the pressure shot up. Maybe the previous owner had it installed wrong, maybe there was a bit of crud stuck in there. Either way my 3 point is fixed and I知 ready to till, now, drill holes.

Thanks all who read the post and offered suggestions.

Thanks for update. I'm glad you got it going. Factory stand-by hyd pressure should be set at 2250 psi.

The pressure should be 2250 as the tractor is at idle speed?
