This is just a "before" picture. Showing what it is that I am working on.

Numbers on the side of the distributor, for reference.

"This looks odd" you say? Yes, it is an ignition rotor out of *I think* a Porsche 911 (1965-69). It has a small weight that is held in place with a spring. As the rotor spins faster and faster the weight slides out and when the rotor hits 7100 rpm... it grounds out the coil and cuts the spark. A simple rev limiter!

I plan on using either an MSD 6AL or a Pertronix Rev Limiter to go with this distributor so I will remove this rotor and replace it with a standard one.

The numbers you see on it don't seem to be a part number as I can't match them to any Bosch part number database?
The 7100 is the RPM point it is supposed to cut the revs at.

Here's what it looks like with the rotor removed. Note that this distributor has had the vacuum advance removed.

Another view of the points setup we are about to remove.

The box! As you can see, this is Pertronix Part Number 1847V.

This is what comes in the box.

Removing the spade connector.

I don't know why I did this. I think I was just thinking that if I ended up wanting to return to the points setup, this might be good information to have.

Removing the points!

Out they come!

Empty.

Fitting the Pertronix bottom plate.

Testing the fit of the provided screw.

Applying threadlocker to said screw.

Removing the connection for the points to the condensor/coil from the housing. The condensor isn't used with the Pertronix anyway so I could have removed the whole thing at this point.

Fitting the spacer. BTW, don't bother. I had to remove it later as it spaced the sensor up too high.

Fitting the sensor.

Fitting the nut to hold down one side of the sensor, the pivot side.

Fitting the nut that locks the adjustment-side of the sensor.

This is the magnet ring. If you look closely you can see that the inner diameter is a rounded off square that matches the cam profile on the distributor shaft. So you can't misalign the magnets.

The magnet ring simply slides over the distributor shaft.

Be sure and slide it down all the way!

Hmmm. That spacer plate I put in is awfully close to being in the way. And it makes the sensor sit to high in relation to the magnet ring anyway.

I've removed the spacer and am now refitting the sensor.

Much better.

Making the pivot nut snug while the clear plastic gap gauge is in place.

Tightening the adjuster nut with the clear plastic gap gauge in place. Note: It doesn't matter where in the rotation the distributor shaft is, the spacing is the same all the way around on a circle. ;-)

Slide the grommet up the wires and insert it in place on the distributor housing.

This is the standard distributor rotor.

Installing...

Installed!

Neat huh?

Cap it off.
