Ignition Lock Cylinder - Tilt Steering Column

Ignition Lock Cylinder-Tilt Steering Column

Removal

1. Disconnect the battery ground cable. Remove the steering column trim shrouds.






2. Tape the gap between the steering wheel hub and the cover casting. Cover the entire circumference of the casting. Also cover the adjacent seat and floor area with a suitable covering to protect the surrounding interior upholstery. Pull out the hazard flasher switch and tape it down toward the floor to provide clearance for drilling out the lock cylinder retainer pin.

3. The tilt column lock cylinder retaining pin is located on the outside of the steering column cover casting adjacent to the hazard flasher button.






4. Tilt the steering column to the full up position and prepunch the lock cylinder retaining pin with a prick punch. Using a 3.17mm (1/8 inch) diameter drill with a right angle drive, drill out the retaining pin, going no deeper than 12.7mm (1 /2 inch).

NOTE: When drilling out the retaining pin, take care not to damage the cover cast housing or the hazard flasher switch.






5. Tilt the steering column to the full down position. Place a chisel at the base of the ignition lock cylinder cap, and, using a hammer, strike the chisel with sharp blows to break the cap away from the lock cylinder.






6. Using a 9.8mm (3/8 inch) diameter drill, drill down the middle of the ignition lock key slot approximately 45mm (1-3/4 inch) until the lock cylinder breaks loose from the steering column cover casting. Remove the lock cylinder, and the drill shavings from the base of the cover cast housing.

7. Remove the steering wheel and pad.

8. Remove the turn signal lever from the column and then remove the two attaching screws from the turn signal switch and one attaching screw from the key warning buzzer terminal. Lift the turn signal switch up and over the end of the steering shaft but do not disconnect it from the wiring harness.

9. Remove the four attaching screws from the cover casting and lift the casting over the end of the steering shaft allowing the turn signal switch to pass through the cover casting. The removal of the cover casting will expose the upper actuator. Remove the upper actuator.

10. Remove the drive gear, snap ring and washer from the cover casting along with the upper actuator mentioned above. Thoroughly clean the components in an acceptable cleaning solution. Carefully inspect all components for any damage resulting from the drilling operation. If any of the components show signs of damage, they must be replaced. Clean the removed cover casting with compressed air to remove any drill shavings or foreign particles and carefully inspect it for damage. If the cover casting is damaged, replace it with a new one primed and painted to match the existing column.

Installation

1. Lubricate the tang of the lock cylinder with grease.

2. Attach the upper actuator to the lower actuator and lubricate the upper actuator. Reassemble the cover casting, upper actuator, turn signal switch and lever, lock drive gear, lock cylinder, steering wheel and pad, and the steering column trim shrouds.

3. Using the ignition key, rotate the lock cylinder to insure correct mechanical operation in all positions

4. Connect the battery ground cable.

5. Check for proper start in Park or Neutral. Also check to make certain that the start circuit cannot be actuated in the Drive and Reverse positions.
