Power Steering right turn less force than left

Post by cash667 »

hi folks,
I´ve got a 68 F250 w/ power steering. Converted the old bendix box to saginaw style.
Since the conversion, right turns need much less force than left turns. Never tried the old bendix box since it was leaking like hell.

My questions:
as far as I know there is no adjustment on the saginaw gear to correct this problem?
When looking in the diagrams I just see a "centering shim"; but it seems just to center the valve spool in it´s axial direction. If I got the function right, it´s a torsion bar control valve and the power is directed by radial movement of the shaft (*38668) within the valve spool.

Do I miss something? Any thoughts on this?

appreciate
Chris
