I'm guessing you have the donor hydro in place, since it's all buttoned up?

Yes, I replace the failed hydro with another working one. I tested it with a drill before I removed it from the rear end it came attached to. It worked fine. I replaced the old manual relief valves with the two new ones from the failed hydro. Guess what? It stopped working. Put the manual valves back in, and it worked. So that's what I installed in the grader.
This test revealed that it's likely that my problem with the "failed" hydro was that BOTH of the new relief valves had failed. How odd.
I reinstalled the loose bearing with bearing set adhesive and reassembled the "failed" hydro. Put a different pair of relief valves in it and it works now.
Apparently the replacement valves I installed were both bad when I originally tested with replacement valves.
