Lock Cylinder (Non-Functional): Installation

NOTE: Ensure 2 sector gears are properly aligned in OFF-LOCK position, or lock cylinder and ignition switch will be improperly timed.

Insert key in lock cylinder, and turn ignition switch to LOCK position. Align locking and position tabs with slots in lock module assembly and press lock cylinder into position. Turn lock cylinder to ACC position, and check alignment of arrows on sector gears (arrows should be pointing at each other). Turn lock cylinder back to OFF-LOCK position.
2. To complete installation, reverse removal procedure. When installing turn signal canceling cam, lubricate lower brass surface with synthetic grease. Use NEW shaft lock retaining ring. Tighten all screws to specification. See TORQUE SPECIFICATIONS . Adjust park lock cable, if necessary. See PARK LOCK CABLE  under ADJUSTMENTS.
