I`m I correct in thinking that I can pull the pitman arm. Turn the wheel to left slightly , make sure wheels are
centered and put the pitman arm back on and pull/reset the steering wheel to center?
There are a couple of ways to correct an off-center midpoint. On a normal steering system the steering box is locked at the midpoint and the tie rods are adjusted so the wheels point straight ahead. If you have an adjustable drag link on a power steering conversion of a straight axle, the drag link adjustment can accomplish the same centering process. If the drag link isn't adjustable, you're going to have to remove the Pitman arm and file some teeth. There are four double width teeth on the Pitman arm that engage with wide areas of the sector shaft so the Pitman only fits at 90 degree intervals. By splitting those wide teeth with a 3-cornered file, the Pitman arm can be clocked one tooth at a time to get closer to equal movement in both directions. An adjustable drag link consisting of two tie rod ends and a turnbuckle adjusting sleeve in the middle is the only way to get things exactly equal.
