Case 310B Power Steering

I R&R'd the o-rings on the spool in the power steering valve of my 1958 310B Gas Utility to stop a leak on an otherwise normally operating power steering. The o-rings are the high-pressure type from Case. When put back together, filled with power steering fluid & turned lock to lock a half dozen times, I had no power steering. As the Eaton style belt driven pump was original, I fingered it as the culprit, so it was replaced with a new gear driven pump from All States Ag Parts and two new hoses, still no P/S. I took the relief valve in the valve body apart, which was clean & no scoring on the ball, back together, still no P/S. The valve body/cylinder is very clean & has all parts in the proper sequence as per my 1960 Case 310B Service & Parts Manuals. Any suggestions will be greatly appreciated, thanks!
 
I'm having the same problem with my 210b and all I did was take the hoses off to paint. It is gradually getting better on it's own. What I've been reading is to put the tractor on blocks and turn the steering all the way left and right several times with the engine running to work air out of the system. I hate to screw up the paint to do this though.
 
I did turn the steering lock to lock six or so times while up on blocks; I was amazed that the power steering hadn't resolved itself as I had narrowed it down to the relief valve in the valve body being stuck open. Maybe I should paint it; at least it would look nice!
