On later models, avoid disassembling the distributor; replace if damaged. Disconnect the battery's negative terminal. Remove the distributor, generator,
Igniter, and vacuum advance. Take out screws holding the generator plate, checking for smooth rotation. If not, replace it. For distributor gear removal, grind set pin ends and knock out. If stuck, use a gear puller. To install, align and tap a new pin into place, securing its ends. Ensure generator base plate aligns with distributor grooves and that the vacuum advance pin is correct. Reassemble by reversing the disassembly steps and adjust the rotor air gap accordingly.
