I bought a 1066 Hydro a couple months ago. The power steering was very weak. The transmission is the new style housing but the steering supply and return lines were plumbed to the old style routing. I checked the flow divider and it was in upside down and the spring was wrecked. I got a new spring and put it in correctly and the steering was a touch better. I swapped a steering safety valve out of another hydro I have and no better improvement. I have a flow rater so I put it on and the charge circuit pressure was in specs but the flow was not registering on the meter so I assume very little flow. Also, when I restricted the flow, the pressure only went up to about 700psi instead of at least 2000psi. I tried switching the return and supply hoses to the proper ports and that resulted in no power steering what so ever and very difficult to turn. I checked the servo pressure and that was also good. Hand pump is also good. Any thoughts would be much appreciated.
