Key Switch Assembly

Table 3-5 lists the few things that can go wrong with the key switch assembly. You should regularly oil the assembly.

Oiling the Key Switch Assembly

The key switch bezel ring and shaft should be oiled regularly, or when turning the key switch becomes difficult or the key squeaks.

1. Take out the dashboard. See the procedure in the section Removing the Dashboard.

2. Lightly oil the bezel, shaft, and spring of the key switch. See Figure 3-6. Check to make sure the spring is not broken. If it is, then replace the spring following the procedure under Repairing the Key Switch.

3. Put the dashboard back in. See the procedure in the section Installing the Dashboard.

Replacing the Spring in the Key Switch Assembly

1. Remove the dashboard. Follow the procedure in the section Removing the Dashboard.

2. Take the key switch assembly off the dashboard by removing the two carriage bolts and locknuts.

3. Start disassembling the key switch by removing the retaining ring from the back of the case.

4. Loosen the socket head screw on the brass actuator with a 5/32-inch Allen head wrench. This screw tightens the actuator on the shaft.

5. Remove the other retaining ring inside of the case. Pull out the key. Take out the brass actuator, the old spring, and the nylon washer.

6. Put one end of the spring into the hole in the side of the case. Push the shaft back into the case far enough to mount the spring on the shaft. You may have to cut the legs of the spring to the correct length so that they do not interfere with the operation of the assembly.

7. Put the brass actuator into the case. The pin on the actuator should face the key and be on the opposite side of the assembly from the switch. Catch the free end of the spring under the pin. Install the nylon washer and the actuator on the shaft.

8. Push the shaft through the case and install the two retaining rings. Position the actuator on the shaft so that it lines up with the roller on the switch. Tighten the socket-head screw on the actuator.

9. When the brass actuator is against the case opposite the switch, the key should be straight up and down. If the key isn't straight up and down, loosen the screw on the actuator. Turn the key until it is straight up and down. Tighten the screw on the actuator to hold it in place on the shaft.

10. Now turn the key so the actuator is against the case on the same side as the switch. Release the key, hold the actuator against the switch, and adjust the position of the switch. The switch must be close enough so that the actuator engages the
