ididit Retrofit Steering Column: Tri-Five Chevy - Manual (Page 7)

Synchronizing your Column
In order to insure proper functioning, this steering column must be installed in
sync with the rest of the steering system. Turn signal cancellation and wheel
position, as well as smooth steering operation depends on it. Although not all
of them may need adjustment, the complete table of steps required for full
synchronization is as follows:
1. The front wheels must be pointing straight forward with the steering toe
set reasonably close.
2. Rotate the input shaft of the gearbox or rack from lock to lock and set the
box exactly half way between. For example, if the shaft rotates three full
turns from lock to lock. The center will be at 1½ turns from either locked
position.
3. Install the steering arm and drag link, and adjust tie rod ends to get the drag
link to fit without moving either the box/rack or the front wheels. Rotating
each tie rod end the same number of turns will preserve adjustment.
4. (When using a Rack & Pinion #4 may apply) With the column mounted
in position and two joints are used on
a shaft, the forks of the yokes closest
to each other should be in line, or “in
phase”. Premature wear or binding
can result if the u-joints are not phased
properly. Sometimes if the u-joints are
at a severe angle, even if they are phased
correctly, a hard spot in the steering may occur for no apparent reason. If
this happens, index the u-joints two or three splines in one direction. The
hard spot should disappear or be minimized.
5. Install the shaft or joint on the gear box/rack. Leave the upper part of the
shaft unconnected for the time being.
6. Position the column housing so that the signal switch arm is level to the
left hand side.
7. Install the column through firewall, into your joint.
8. To achieve proper
synchronizing of your
column the finished
installation of your
column should look
like the diagram on the
right. If post on horn
cam is not at 10:30,
turn it until it is in the
10:30 position. Once
completed, your column will be in sync.
