Survey the damage, folks. The sector gear (arrow) was so trashed that we couldnt operate the ignition switch at all. We placed a small screwdriver on the flat surface of the gear, and tapped it off the metal shaft. Push the new gear on until you feel a positive click. The gear should turn freely when correctly installed. When you reassemble the column, make sure the big tooth on the sector gear aligns with the big slot on the rack.
