Disassembly Procedure

NOTE: The OBD II ignition system distributor driven gear and rotor may be installed in multiple positions. In order to avoid mistakes, mark the distributor on the following components in order to ensure the same mounting position upon reassembly:
^ The distributor driven gear
^ The distributor shaft
^ The rotor holes

Installing the driven gear 180 degrees out of alignment, or locating the rotor in the wrong holes, will cause a no-start condition. Premature engine wear or damage may result.




1. Remove the two screws that hold the distributor cap to the housing.
2. Discard the screws.
3. Remove the distributor cap from the housing.




4. Align white paint mark on the bottom stem of the distributor, and the pre-drilled indent hole in the bottom of the gear (3).
5. With the gear in this position, the rotor segment should be positioned as shown for a V6 engine (1) or V8 engine (2) If not, replace the distributor.




6. Remove the two screws from the rotor.
7. Remove the rotor.




8. Note the locating holes that the rotor was removed from:
^ The rotor screw holes (1)
^ The rotor locator pin holes (2)




9. Remove the two screws that hold the camshaft position (CMP) sensor.
10. Discard the screws.




11. Line up the square-cut hole in the vane wheel with the CMP sensor.




12. Remove the CMP sensor.
13. Note the dimple boated below the roll pin hole on one side of the gear. The dimple will be used to properly orient the gear onto the shaft during reassembly.

CAUTION: Refer to Safety Glasses Caution in Service Precautions.




14. Support the distributor drive gear in a V-block or similar fixture.
15. Drive out the roll pin with a suitable punch.
