A couple of months ago I bought a 1967 Valiant 225 slant 6 and power steering, disc brakes in front, 4-1/2 inch bolt pattern on all four and 2 bbl carter carb with intake.

I just replaced the whole front end with 75 parts and rebuilt the power steering box, which is date coded 3061. (As I understand 306th day if 1971.) When we tried to adjust the neutral setting on the top of the box we cannot get it to center. It is very sensitive. Does anyone have any suggestions?
 
If the wheels turn both ways as you slide the control valve back and forth, you probably have it assembled correctly and just need the right taps on the hammer to center the spool valve. I tried a rebuild (rubber parts and gaskets) long ago on my 69 Dart, but the steering would jam only one way. Gave up after 2 attempts and got a rebuilt box. Later and wiser, I tried on my 65 Dart and worked fine. I think the trick I missed originally is that you must keep the input rod turned tight one way (ccw, I recall) to hold all the disks tightly together as you slide the guts in and secure the input collar nut. If not, some disks can shift out of position.
 
I think if you are getting left and right pressure steer from that adjustment the sweet spot is there. I can't get it with the bolts loose enough to adjust by hand. With the bolts barely loosened so tapping with a small hammer moves it a hair per tap gets me close enough.
For what its worth, The very best fellow service tech I've ever known couldn't successfully renew a worn out steering gear in a old Dodge p/u and believe me, He tried. Wasn't his first rodeo either. Seems something about this particular box was just too far worn. Therefore I would never attempt it. I just buy reman'd. Good luck with it.

I didn't take the big nut off of the input shaft was told not to touch, just replaced all of the "O" rings and seals. Have tried just barely loosening the two bolts on top and sliding it in very small movements with the tap of a small hammer. It doesn't take much to move from right to left.

Thanks, I know it is there it worked ok before I put the "O" rings and seals in. I guess I just need to be more patient.

When we get to the sweet spot where the wheel is in the neutral position and we turn it one way or the other and let go of the wheel, it wants to turn to full lock all by itself.
