Distributor drive gear pin removal

Thanks to Charlie Mullendore of Antietam Classic Cycle for providing me his methodology in a private communication.

The pin thate holds the distributor drive gear in place can be extremely difficult to remove. Charlie shares his methodolody:

Just removed two pins very easily last week doing this same exact swap. Here's what works for me:

  1. grind the peened head off one end.
  2. tap the pin in from the other end with a hammer and punch (helps you to see the pin on the ground end for the next step).
  3. centerpunch the pin and drill the remaining head off (I used a 3/16" bit IIRC). You don't need to drill very deep, more a countersink.
  4. using a good quality 1/8" punch, drive the pin out.

Reinstallation is very easy, tap the pin in and peen both ends. Here's a few shots of the crude fixture I made for the job out of 3/8" thick steel.
