1530 John deere steering

[sgoerdt]

The power steering on my 1530 works but when I turn to the right it has some hesitation almost as thought it is pulsing or have to overcome pressure and then has a whine sound. No hesitation or sound when turning to the left. No hydraulic leaks everything else works as it should. Any help on diagnosing the problem would be greatly appreciated.

My guess is one or more of the 6 large o-rings inside valve housing has failed or the RH control valve has failed. Due to the cost of the individual control valve(AR81610 @ $1382 each) I'll recommend to 1st R&R of the 6 o-rings. These 6 o-rings can be replaced by removing steering wheel & large adjusting nut, then turn shaft CCW to remove shaft assembly with valves, shims intact. Don't disassemble valves & shims without documenting location of each shim.
