Figure 3-4 Steering Wheel Is Very Jerky and You Have Tried the Set Controls Screens
4 Hold the new potentiometer with the shaft facing you and turn its shaft as far as it can go in the counterclockwise direction. Then turn the shaft back about 15 degrees clockwise.
5. Face the stop bracket on the end of the motor; then turn the motor shaft as far as it will go in the clockwise direction.
6. Install the potentiometer in the potentiometer bracket on the end of the motor with the flat of the potentiometer shaft under the set screw and the potentiometer key in the keyhole in the bracket. If the flat part of the shaft is not under the set screw, then repeat steps 5 and 6.
7. Put the lock washer and nut on the potentiometer bracket and tighten the nut. Be sure you do not turn the potentiometer shaft from the position at which you set it.
8. Insert the potentiometer shaft into the motor shaft; tighten the socket-head set screw.
9. Check the alignment of the potentiometer and the motor by very carefully turning the steering wheel as far as it will go clockwise and counterclockwise. Check to see that the potentiometer does not come to its own stop, but continues to turn as far as the steering wheel turns in both directions. If the potentiometer does come to its own stop, then do steps 4 through 8 again.
10. Put the dashboard back in the simulator, following the instructions in the section Installing the Dashboard.
