Take the distributor hold down out, it is right behind the dis, a 1/2" bolt. Then take the dis out of the engine, turn it over, find the pin that goes through the gear and knock it out, I find a small nail works well. Then the gear will come off with a little persuasion. Hold the top end with your hand, work the gear with a pair of pliers. It will come off. Then the shaft will pull out of the distributor housing.
