Classic Ford Mustang Ignition - How To: Rebuild a Distributor

Remove the two screws to detach the breaker plate. Marvin will blueprint this breaker plate for smooth operation.		 How To Rebuild A Distributor Removing The Distributor Cam
Removing the distributor cam from the shaft isn't easy. The retainer clip is worked inside the shaft while pulling up on the cam. This is a balancing act requiring a lot of patience and coordination.

A hydraulic press or bench arbor can also be used.
How To Rebuild A Distributor Distributor Shaft Wear
Marvin measures the distributor shaft for excessive wear. Minimum allowable dimensions are 0.0015-0.0025 inch. For our subject distributor, Marvin recommends a new shaft and a duo of fresh bushings for the housing. Forget going to your local Ford dealer because these bushings are now obsolete. Check with any number of bearing companies. Distributor bushings aren't unique to only distributors. However, you want oil-impregnated bronze bushings for distributors, which are compatible with a steel shaft.		 How To Rebuild A Distributor New Parts
Here's everything you need for a complete distributor blueprinting, excluding bushings. Marvin has opted for the gray cap because it offers the greatest dielectric resistance to cross-fire. We're using the PerTronix Ignitor II electronic-ignition retrofit for reliability and better performance. Note the adjustable vacuum-advance unit. If you want original equipment, look to AMK Products for OEM, shim-style vacuum-advance units.		 How To Rebuild A Distributor Shaft
Marvin has installed new bushings and lubricated the shaft with his own assembly lube mix. Shaft endplay should be 0.024-0.035 inch.
