Corvette Power Steering Question C3
I have replaced the power steering control valve, power steering piston and pump. Soon I will have everything together and will start it, I have been working on the car for over a year, getting close. My question is this, the instructions on the P S valve states do not connect the piston to the frame when starting for the first time ? Do I let the piston rod hang down when starting ? What should I do to protect the piston end from slamming into the frame?, will it do that ? Then, how do I adjust the valve ? when doing the adjustment, what am I looking for?, center the steering wheel ? Any suggestions would be greatly appreciated. I should have it running is a week or so.

You should get a service manual; they are extremly helpful.
Let the cylinder rod hang down so that it will not interfear with anything when fully extended. After you have done the bleeding, balance the valve: Take the cap off the cv, you will be turning the nut inside but only very slightly. The idea is to get the cylinder rod not to move. If it starts moving turn the nut in the direction that makes the rod move in the opposite direction. Now turn the nut the other way, the rod will again change direction. Again, this only takes a small amount adjusting. You can do this change in direction a couple times to get a good idea where center is, i.e. the point at which the rod does not move in either direction. Put the cap back on, your done.

I pretty much agree with 70. As a further refinement, if the piston fully extends, turn the nut in the control valve counterclockwise (I think) and CAREFULLY COUNT THE NUMBER OF TURNS to make the piston retract. Then turn the nut in the oposite direction half the number of turns. Done.
