INSTALLATION




1. Set the front wheels in the straight-ahead position.

The neutral position is detected by turning right about 2.5 revolutions from the left end position. Align the matching marks made during removal.

CAUTION
- The spiral cable may snap due to steering operation if the cable is installed in an improper position.
- Also, with the steering linkage disconnected, the cable may snap by turning the steering wheel beyond the limited number of turns. The spiral cable can be turned to the right about 2.5 turns from the left end position.
