Where I circled is that the priority valve spool my steering is hard to turn. I replaced seals in turn cylinder and that didnt help so Im hoping the valve has some trash in it that has the valve stuck open/closed. The orbitle valve is working as it should. Screen in suction line is clean and filter has been changed as well as fluid Kubota udt2. Been rebuiling tractor.

Why not check for flow at the steering valve?

dont have the right fitting for guage. I got this unit on the cheap and restored it trans/hydraulic tank was really dirty screen was packed full of debris cleaned screen changed filter and fluid repeated the process. Steering did not work when I finally got the tractor started so I removed cylinder and repacked it bled air and still no power steering at fel line I put my guage on and got about 1100 psi so Im low on presure so I put a .1 , .2 and a .4 shim in releif valve that got me about 1300 still way low presure. FEL works fine and runs great forward and reverse. So I thought the priority valve spool may have trash in it. I think the pump is good but it may be wore out not sure. So I thought maybee someone could tell me where the priority spool was so I could pull it and check for trash. Or maybee I need to pull that whole valve assembly. I have totaly restored and painted. Working on backhoe next.
