      • THIS CAN BE A SENSITIVE REPAIR THAT IF NOT DONE CORRECTLY WILL MOST LIKELY RESULT IN IGNITION FAILURE AND OR

ENGINE DAMAGE.***

        • DISCLAIMER:****
        • THE FOREGOING IS A GUIDE AS I RECALL THE STEPS OF THE REPAIR TO BE, I AM RATHER THOROUGH IN EXPLAINING THE

PROCEDURE, HOWEVER, YOU SHOULD CONSULT A PROPER REPAIR MANUAL FOR GUIDANCE AND OR VERIFICATION.

FIND **TOP DEAD CENTER (TDC) (**crucial step) FOR CYLINDER #1; CONSULT A PROPER REPAIR MANUAL OR FORD MOTOR CO..

DISCONNECT BATTERY TO PREVENT MOVEMENT OF THE TOP DEAD CTR POSITION.

CLEAN THE BASE AROUND THE DISTRIBUTOR SHAFT TO PREVENT DEBRIS FROM FALLING INTO ENGINE.

    • SCRIBE, **SCRATCH OR **OTHERWISE MARK SHAFT AND MOTOR BLOCK TO ASSURE PROPER ALIGNMENT FOR REINSTALLATION.

REMOVE THE BOLT AT THE BASE OF THE SHAFT, IT USUALLY HOLDS A THICK WEIRD LOOKING EGG SHAPED WASHER TO THE BLOCK. **if you dont mark the shaft to block, the engine will have to be timed.

YOU MUST THEN SLOWLY REMOVE THE ENTIRE DISTRIBUTOR, NOT JUST THE CAP.

ONCE THE SHAFT IS OUT, LAY IT DOWN ON A SOFT SURFACE, LIKE A TOWEL, TO PREVENT DAMAGE.

INSPECT DISTRIBUTOR GEAR AT END AND OTHER PARTS FOR WEAR, AND REPLACE ONLY IF NECESSARY.

REMOVE OLD MODULE; IF ITS MOTORCRAFT, ITS USUALLY GREY.

CLEAN MOUNTING PLATE, IT MAY HAVE TO BE CLEANED GENTLY WITH RUBBING ALCOHOL AND A COTTON BALL TO REMOVE ANY DIELECTRIC GREASE THAT MAY REMAIN. ***DO NOT USE A SCRAPING TOOL OF ANY KIND OF THE MODULE OR MOUNTING PLATE!***

LET THE DISTRIBUTOR DRY COMPLETELY.

THERE IS USUALLY A SMALL TUBE OF DIELECTRIC GREASE WITH THE NEW MODULE WHICH MUST BE USED. IF NOT INCLUDED, YOU MUST BUY A TUBE OF DIELECTRIC GREASE. ***THE MODULE MUST NOT UNDER ANY CIRCUMSTANCES BE REPLACED WITHOUT THE GREASE!***

GENEROUSLY APPLY SAID GREASE TO THE NOW SHINY PART OF THE MODULE MOUNTING PLATE.

MAKE SURE THE NEW MODULE IS CLEAN, THEN MOUNT MODULE TO MOUNTING PLATE ON DISTRIBUTOR SHAFT.

DO NOT OVER TIGHTEN SCREWS!

CLEAN OFF ANY RESIDUAL GREASE FROM SURROUNDING AREA.

CAREFULLY REPLACE DISTRIBUTOR SHAFT.

REALIGN THE MARK YOU MADE EARLIER ON THE DISTRIBUTOR SHAFT TO THE MARK ON THE ENGINE BLOCK.

REPLACE THE WASHER THEN THE BOLT AND TIGHTEN TO SPECS.

RECONNECT THE MODULE HARNESS THEN THE BATTERY CABLE AND START THE CAR.

GOOD LUCK!
