bc the 2606 does use the same flow divider as a 656 I see. In that valve the orfice is not in the spool but is a seperate disc pressed into the casting, on the end of valve where the two large lines come in ,it is under the middle smaller plug. Haven't seen any of these type spools wear much at all , have had some of the disc's come out , bust up etc. That usually causes a different type of problem though as all the pump supply then goes to power steering causing lines to vibrate , noise, break etc. The valve on the other end, relief valve does have an adj screw but is factory staked. Could work loose and cause low pressure, or o-ring on bottom end of valve could be bad. One other thing, some of the 656 tractors had a T screw in that center fitting, the idea was to screw that in making cold starting easier. That was somebody's day dream I guess. but if you did have that on your valve you would want to be sure it was not screwed in part way. What one needs of course is a inline flow rater to check flow and pressure but am sure that is not an option so you just have to keep trying different things and picking people's brains.

I’d probably plowed about 3000 acres (in my head anyway) by the time they found me. This is where my love for tractors started and has only gotten worse in my tender 50 yrs on this “green planet”. I’m par
