Morning all,

Newbie here. I've been on the Corvette Forum for a while now and have had Big Bird on the job a couple of times. Great guy.

My first question for this forum is regarding the power steering control valve for a '75 auto. I swapped out the hoses and cylinder no problem but what's the trick to swap out the valve? I see the boss end has a spline clamped via the bolt - no problem; and the bracket on the valve to the pitman arm is perpendicular to this fixing. So... how do you drop it? Do you have to undo the pitman arm as well?

Thanks guys...

remove the steering valve tapered stud from the pitman arm, then remove the valve from the centerlink (of course also remove hoses), that's al

MY recollection is you have to adjust how far you screw the new valve on that cross shaft end....it has to do with the amount of play on the input shaft/morse taper/ball stud....then you have to adjust the end nut for neutrality in the assist ram......been over ten years since I did that, so sweet memories.....NOT!!!.....

not all that bad a job, just need read the shop manual on it....

Cheers guys,
I had a look under there yesterday but not wanting to wreck anything I didn't force the issue- but then again I did do the 'man thing' of not reading the manual first....

the balancing is done when installing, setting the valve to not assist L or R w/ the little lock nut behind the dust cap. The play is set internally by a ball adjsuter nut (it's backed by a spring), it has nothing to do with how far you screw it on the centerlink. It should go on all the way. You have to pull that stuff apart more often, keeps your memory fresh LOL :rolling:
