I found the 3874876 in a late 80s 4 dr single barrel Aspen this weekend. I know Duster said ............also found on Federal one barrel cars after 1977.............I dont understand what this means, what is a federal ?

It was nice to open it up and see the difference in the primary spring when compared to the other dist I had torn down. Its loop was much smaller which would make the mechanical advance happen that much quicker, really neat to see the differences in how much throw was required to move the weights.

I have a few questions.

1- The vacuum pod that was on the dist had marked on the arm ( first time I had seen one of these marks ) 11.0 R which according to Duster would be the correct can for the dist.

While the can appears to be functioning fine and holding a vacuum I would like to get a replacement can and am trying to do so thru Old car parts N.W.

I gave the guy there a part # of 4876 which I thought might help but he says no good. Can someone tell me a part number he might be able to identify his boxes with? What was the original Super six canister part # ?

I see a # on this pods bracket ( where it bolts to dist. ) and I believe it reads 38778. Very hard to read cause of the way it was stamped, might be a 88778, might be there are digits just missing where they punched the mounting hole. Hard to say.

2- I thought I had read an article on this forum that dealt with re-building these cans, dissasembly and re-furbush but I cannot seem to find it, can this be done?

3- This can does not have the hex nipple on it, does that mean it is non-adjustable? Why do they mold the can to have the hex shaped end as if one could use a big wrench on it?

4- Duster and Reed I believe mentioned that all OEM dist bodies ( electronic at least ) were aluminum body. I am considering buying a brand new dist just for the housing at least and swapping over parts from other dist just to make one new Super six dist.

Ray at Old Car parts N.W has a 3874082 dist that someone evidently here suggested to him that I may want to use for my truck, he also has a 3874714.

I dont know the original applications for these dist, what they were originally set-up for, being brand new I am trying to get a dist from him that will have the most parts within it that I can use.

5- This dist that I picked up over the weekend is extremely tight, I can remember seeing this car parked in the same spot about 15-18 years ago sunk down in the mud amidst other Mopar relics so I know it hasnt been run in at least that long.

I chipped a tooth of the gear pulling it out, Id like to completely disassemble it or at least remove the main shaft from the aluminum housing so I can do a thorough inspection and cleaning.

Is this just as easy as removing the pin, pulling off the gear and then lifting shaft out of housing?



Thanks once again

Emissions standards, anything in the regular United States, gets "Federal" standards and equipment...you would not get this distributor if it were a 1-barrel California car.
I do not have access to my later parts manuals to give you a part number for that. The number stamped on the mounting flange is the same regardless of year and is worthless for getting a new pod.
By the time you mess with it, and make it work, it'd be easier to buy a can at $20...
It should being an OEM can...either 1) the allen key wasn't inserted deep enough, or 2) the hex is filled with smut from years of neglected cracked vacuum advance lines and road grunge, or 3) it seized and the previous mechanic rounded the hex socket out by the meat fisted twist of the wrist.
I vote for #2.

I would get the 714 distributor that will give you an 11R governor to play with later if you want...3874082 is a 1975 distributor and has the 15L governor...and not very desired.

Unfortunately it is going to be ugly. I would drive the pin out and toss the gear. (Old gears we trash since they are petrified and not worth running in your regular ride.)

The shaft is going to be seized or really tight. If it moved easily, it will probably get hung up on the "wear" spots and junk in the bushings.
I squirt the shaft and the bottom vent holes with PB blaster, wait a few hours...if I get a little movement, then I'll do it again, then chuck it up in my Dewalt Cordless and a vice and spin the shaft until it's free. I then chuck the governor up and use a little emery cloth on the shaft on the bottom. If might come out with some wiggling at that point....If not, turn it upside-down over a piece of 4x4 box iron, and use a punch and mallet and drive the mainshaft out of the body. Clean everything thoroughly...I then mic the mainshaft so I can determine how far gone it is compared to the bushings in the body I'm going to do the transplant...In this case it' sounds like you will just use the new OEM distributor and swap the springs and governor....at which point I would make sure to keep the old mainshaft and index the spring posts on the new mainshaft to match the old one.

Thanks Duster.

1- By the time you mess with it, and make it work, it'd be easier to buy a can at $20...

1- I do not know a good part number for the pod I need, alot of info on here that I am trying to work thru concerning good part numbers. From what I have read it was VC-239 but now is VC 3034 part number.? Is that correct?

Is this the pod with the 11.0 arm? Same as original Super six or as close as can be expected ?

2- It should being an OEM can...either 1) the allen key wasn't inserted deep enough, or 2) the hex is filled with smut from years of neglected cracked vacuum advance lines and road grunge, or 3) it seized and the previous mechanic rounded the hex socket out by the meat fisted twist of the wrist.
I vote for #2.

2- I thought I had read an article on here and it showed a pod with the nipple end ( where the Allen key inserts ) in the shape of the hex. I thought that this was the only adjustable type. I thought that the round nipple ends were not adjustable. I did not bother to try any of the ones I have cause I was certain I had read that here on this forum.

3- I would get the 714 distributor that will give you an 11R governor to play with later if you want...3874082 is a 1975 distributor and has the 15L governor...and not very desired.

3- That is what I will do than. You said in an earlier post that all OEM bodies were aluminum, I am not sure if you meant all OEM Super six bodies or all OEM slant dist bodies.

I have read a past post of yours that I believe said all 1973 up ( to what year I do not know ) dist bodies were the same so I am assuming that all internals will interchange between distributors. Is that correct ?

4- Thanks for the tips on the dist. It was pretty well seized when I pulled it out, with just a few minutes of playing with it I have freed it so it spins, it just does not spin smoothly. Id like to take it apart just to see how they come apart.

I have read several posts on here about installing a new gear, havent got that far into it yet, from what I understand something about cant use the hole pre-drilled in the gear, have to do some drilling myself, also there is only supposed to be a certain amount of movement up and down on shaft when all is said and done.........need to look into all of this yet.

The correct vacuum can would have been the VC-239 by Standard. If you cheap out you can get the same can by Wells/Airtex as the CV3034 (your other number)...at your local Autozone...(same can different packaging).

These no longer have the 11.0x arm on them and are the 8.5 arm, which is fine since you are running a truck and need to limit the vacc advance a bit due to your lack of aerodynamics and the horrid power to weight ratio compared to a 2 door sedan...

Thanks, I am working on getting that Super part # when I have it I will post it here.

See these recent posts for some further information on super six dizzy's.

I did see and read those posts bu thanks again, re-reading things only helps to answer more questions.

A fellow over on this forum http://www.aspenandvolare.com/forumdisp ... el-Systems

( nice group of people ) sent me this info from his 1980 Parts book concerning original part number for Super Six pod. He evidently typed it out as can be read from the parts manual. .................

Description Prod. No.
Vacuum advance pod=Control Vacuum----w/3874876........................................... ......3874 878 ......................

Obviously the 3874876 is the Super dist and typing the 3874 878 into google give me these results

AIRTEX 4V1064
CARQUEST 57-7514
STANDARD MOTOR PRODUCTS VC-239
WELLS CV3034
ECHLIN VC3034
BWD V410

So that must be a good original part number for that pod. Trouble is if memory serves me that Duster has pointed out already that these VC-239 pods are not set up as the originals were.
