308 Pertronix install.....quickly ran into an issue

The time has finally come to swap out the points in my dual dizzy 308 to the Pertronix ignitor setup (MR-182 that I purchased out of Classic Garage in NY) that I have had sitting in a box for a half a year. I am getting sick of changing out fouled plugs all the time. I pulled the back dizzy off, removed both sets of points and quickly noticed a problem.

As you can see from picture #1 that the ignitor plate is a complete plate that runs 360 degrees around the entirety of the dizzy. However in picture #2 my dizzy (Magneti Marelli marked S 159 B, 7D) has some sort of brush and accompanying brush housing protruding out of the surface where the Pertronix mounting plate is supposed to mount up to.

I see three possible solutions to the problem at this point.

1) Remove the brush and grind the brush housing flush with the bottom of the dizzy. Not sure what the purpose of the brush is and am not sure if the dizzy can do without it. It would also take a good bit of grinding as it seem that the housing is in there pretty good.

2) Cut/modify the mounting plate of the Pertronix unit itself. I am kind of a newbie when it comes to dizzys and I am not sure if the plate is magnetic, and if so, if any cutting of the plate can compromise the functionality of the entire Pertronix unit.

3) Look for another/correct Pertronix setup for my application (dual dizzy). At the time of the purchase of my current unit that seemed to be the only thing on the market.

....Another point of confusion is the magnetic sleeve that comes with plate. The directions call to "install magnet sleeve over the distributor shaft. Rotate sleeve until a slight locating position is felt. With sleeve lined up on point cam. press down firmly insuring sleeve is fully seated". The sleeve that was supplied in my kit will not fit on the dizzy shaft without removing the outer bearing that resides between the bearing plate and the dizzy shaft. Should that bearing be removed?

Any help here would be greatly appreciated.

Thanks for the responses.

I guess it sounds like either of the options might work. I thought about trying to get the brush housing off by getting to it from the bottom side of the dizzy, and went ahead and removed the screws off the bottom plate. The plate didn't come out freely so I stopped there, I just had real bad visions of springs and what not shooting out everywhere. It looks like I might be able to access and drill out the rivets from the top though.

The more I think about it, if modifying the plate on the Pertronix unit is a viable option, it might make more sense to go this route as opposed to cutting up the dizzy in case if somebody (other than myself) ever wanted to go back with the points.

 

Going to cut the Pertronix plate and at least try to install the aft distributor tomorrow.

Now can someone correct me if I am wrong but with installation of the dizzy the red dot on the dizzy corresponds with the firing of #1, so I should set the flywheel on TDC for 1-4 with the rotor pointing at the red dot....correct?

 

Alright change of plans. I am going to have to remove the entire brush housing due to clearance issues with Pertronix's magnetic sleeve that has to fit over the dizzy shaft, thanks FiatRN for catching that for me. I have everything opened up. While I am in there I want to clean everything up and re-lube the advance mechanism. Is there a consensus on what to use for lube? I have seen people using generic motor oil before, but I also seem to remember hearing about a specific grease.

 

Thanks for the responses. I ended up using lithium grease to lube up the advance mechanism........hopefully this will be okay.

I am going to reinstall the aft dizzy today, so good timing. I marked the rotor position when I removed the dizzy, but I didn't feel confident with the way everything was running prior to the removal so I want to start back with a clean/correct slate.

 

Aft dizzy is back on the car, lined up the rotor over the red notch for #1 fire and got the motor on the PM1-4 mark (PITA, half thinking about putting some marks on the main pulley on the passenger side of the car).

About to wire the first unit up as I want to get it up and running, and timed correctly, before pulling to the front dizzy just to make it easier to located and track down any potential issues.

I just want to make sure that the red bugger sitting under the coil in the picture is the ballast resistor? I am also assuming that B is '+' in Italian and D is '-'?

Awesome! Thanks!

 

Ok, went to put everything back together today and will hopefully be re-setting the timing tomorrow. I have noted this in the past and thought this was a good opportunity to take a picture of it and pose this question, but this little black module looking thing on the bottom of my coil next to the ballast resistor has been disconnected as long as I have had the car.......anybody have any idea what it is and if it should be reconnected?

It appears to have some markings on the bottom of it, I would have to remove it again to read it though. I believe you are correct. I originally just checked the North American 308 GTB/GTS manual which did not have anything listed in the wiring diagram for the engine electrical system, but I just checked the GT4 manual and it does have a radio suppressor listed..... I have yet to turn on the radio since I have owned the car.
