COP Ignition Development

I made a tool to pull the distributor drive bushing. The tool was made from 10 mm threaded rod, nuts, a couple washers and a small piece of steel. The rod and a VW cylinder head nut, we're chucked in a 4-jaw, so the nut could be turned down as an eccentric. The diameter was sized to just fit the bushing bore. I then made a part that served to push the rod to the side, so the eccentric locked in the bushing. It installs with the tab in line with eccentric bump, then the rod is rotated 1/2 turn, a nut was tightened to hold in place.. A large washer, socket, and nut on top, turned to pull bushing. It worked great.

The drive was replaced, the measured slop was about 2 degrees, the rest is due to the distributor drive tang. I have an idea how to reduce that. I will post if that works.
