861 Electronic Ignition Problem

Hi Ford Forum. I am a first time poster and a below-average Ford mechanic so please bear with me. I converted my 1960 Ford 861 to the Pertronix electronic ignition. My problem is that the black plastic round "button" that goes over the distributor peg and modulates the firing of the spark seems to be too tall and rubs on the underside of the dust cover shoulder. IT eventually rubs the dust cover shoulder completely off and the top of the "button" wears down and eventually separates. The tractor starts to run rough and eventually it won't start or run. Has anybody had the same problem and is there a fix to the problem? Thanks in advance for any help you can give me on this matter.

As others have said, you need to enlarge the hole in the dust cover to clear the magnet sleeve.

If you go to their website, instructions for the 1244A (not the general instructions), it addresses this in bold lettering.

Hundred/01 series locate and secure the cap from turning with the dust shield.(note the little square notch in the edge of the dust shield)
ps. The gasket under the dust cover is important too. Without it, the rotor in some cases will whack the cap terminals.

The dust cover on the 3 cylinder tractors didn't matter other than to keep dust out of the points. On a pre-1965 4 cylinder I believe that the dust cover also acts as a spacer to set the distributor cap up at the proper height to not interfere with the rotor, so eliminating the dust cover altogether on a 4 cylinder would cause other problems.

I used a 3/4 inch diameter hole saw and cut a hole to clear the unit.

I had a problem with the dust cover not fitting on a 3000 Ford when I put Pertronix in it. Can't remember exactly why now.
I just removed the dust cover and ran it for years that way. I sold the tractor eventually and it's still running that way.
Anyone need a dust cover for a 3 cylinder?
It's still in the drawer - 13 years later.

Thinking through this a little!!! The dust cap is not really necessary if there are not points, sooooo grind out the center of the dustcap to make room for the electronic coil.

I did the same thing and it still eventually came in contact with the dust cover shoulder and disintegrated the spark modulator\black button.

Call Pertronix tech number. I had same problem on 8n and they told me I could sand down the top of the "button". I did and it worked.

Thanks for your help everyone. I will try a modified dust-cover and see if it will work first.

The oem parts work as engineered! BUT. The Pertronix set up is not original, some work, some cause problems. We all know that after market caps, rotors etc don't always fit as they should, so every case seems to be a little different.. Will it work without a cap? Maybe?

Thanks for the replies. I thought about just removing the dust cover, but wouldn't that lower the height of the distributor cap and cause the rotor button to be too close to the distributor cap contacts?

You really don't need the dust cover,it was more for the mechanical points,I removed it on my Jubilee long ago when I changed from points.

Quoting Removed, click Modern View to seeIt seems as though that I recall that another poster contacted Pertronix about same problem & was told not to use dust cover.

An extra gasket on the dust cover makes a difference

Today's Featured Article - The Ferguson System Principal An implement cutting through the soil at a certain depth say eight inches requires a certain force or draft to pull it. Obviously that draft will increase if the implement runs deeper than eight inches, and decrease if it runs shallower. Why not use that draft fact to control the depth of work automatically? The draft forces are ... [Read Article]
