The power steering on my 602 works well to the right, but not to the left. According to the repair manual, this can be caused by a sticking control valve spool. I have taken the control valve apart, cleaned all parts, replaced all O-rings, and reassembled - no change. I could not figure out how to remove the relief valve (I assume it is the gray circle on the 2nd picture) - could this be part of the problem and does anyone have suggestions as to how to get it out? Also - the first picture shows a notch in the end of the control valve spool. Is that significant? (I couldn't find a reason or any particular reason to place the notch in any particular position.) Any information or assistance would be appreciated.
