Distributor Disassembly

NOTE: The OBD II ignition system distributor driven gear and rotor can be installed in multiple positions. Be sure to mark the following positions:
^ The distributor driven gear
^ The distributor shaft
^ The rotor holes for the same mounting position upon reassembly
Installing the driven gear 180 off, or locating the rotor in the wrong holes, will cause a no start condition. Also premature wear and damage may result.

NOTE: Failure to keep cleaning agents away from the distributor Hall Effect switch may cause premature failure.
