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
