Steve's Camaro Parts - 1969 Camaro Dissasembly of 1969 Steering Column Lock Cylinders

Disassembly



1. Using a paper clip or similar gauge wire, fashion a tool by placing a 90 degree bend approximately 1/8 inch from one end of the wire.
2. The lock cylinder sleeve incorporates two separte brass plunger pins, approximately 180 degrees apart. Only one of these pins can be used to disassemble the lock cylinder.  The pin is adjacent to the tango on the anti-theft ring and is the incorrect pin to use (see figure 1)
3. The cylinder may be freed from the sleeve with the cylinder in either the "LOCK" or the "ACC" position.

    a. If the "LOCK" position is chosen, use the tool formed in step 1 to depress the correct plunger pin (identified in step 2) approximately 1/8 inch down into the sleeve housing as shown in figure 2. While depressing the pin and maintaining light upward pressure on the lock cylinder, rotate the cylinder counter-clockwise (toward the "ACC" poisition) until the cylinder pops from the sleeve.



    b. If the "ACC" position is chosen, the correct plunger pin (identified in step 2) is flush with the sleeve housing and is not visible. The pin is located directly above the stake mark as shown in figure 2. Using the tool formed in step 1, depress the plunger pin approximately 1/8 inch down into the sleeve housing while maintaining light upward pressure on the lock cylinder until the cylinder pops up from the sleeve.

4. Remove the lock key from the cylinder.
5. Tap the lower end of the sleeve on the work bench several times (on side containing the wire spring and retainer)  Remove the sleeve assembly, anti-theft ring and wave washer from the lock cylinder assembly.
