  • Need help finding distributor parts
  • Found a distributor in my box of spare parts that I would like to finish rebuilding but I can't seem to find the last three parts that are missing. This is an old picture but the blue arrows point to what it needs. Anybody happen to know where I could find these missing parts? Local Napa store has gotten stupid on me and will not sell Echlin parts anymore so I have to order all those parts from RockAuto now. Not to bad they are cheaper anyway.

  • What do you think we've been talking about? Get out your MPC and look at the distributor part exploded view. P/N 91A-12159...then read the follow up posts on where to get a new one...

  • Daley, Don't be hostile.... MY question was about a drawing, NOT what would work or that I NEEDED one.. You didn't use to be so cranky.

  • SOME part drawings can be found at the Benson Ford Research Center in Dearborn, Michigan. They cost money to get scanned copies. When you go there you better have the part numbers, EI sheets numbers, and any other info you want because it is run by a bunch of kids and they don't have time to get off their I-Pods to look up anything. If the part drawing is in the system still, you'll be lucky if it is, then they will download a scanned copy and like I said they charge beaucoup bucks to do that. You cannot do this on-line, you have to go there in person. Why do you need a drawing of a plain Fillister Head Brass Screw for?

    Crankiness comes with old age and I've deserved it...

  • Re: Need help finding distributor parts
  • Whatever Mr. Duey. If I was to get any drawings from the BFRC, it would be for parts that were rare, not a plain screw. I just don't understand why you want to muck around with making something that can be purchased at a low cost. If you want to make something, make a part not easy to find like Dan said -the hard paper or plastic tab. Just my opinion and your mileage may vary...

    Have a pleasant day...

  • Re: Need help finding distributor parts
  • I think it should be a #8 screw not sure on length. Ford part number is 91A-12159 used on the tractor, delivery truck and some sedans in the early 40's. Might just get a handful of brass screws and some copper tubing and make some. Can't use steel because it rusts to easy and won't keep a clean contact.

  • GUYS: The LINK I provided below for the 91A-12159 screw, 8-32 x 3/8" BRASS FILLISTER HEAD SCREW will work just fine.

  • Re: Need help finding distributor parts
  • It's not worth the time, money, and effort to make something that can be easily purchased, in my opinion. Do you have a lathe that can cut threads? Better yet, access to a screw machine? I can see making one or two if you needed to have one now, but to make them on a production level, I'd opt for a CNC Lathe with live tooling to machine the screw slot in. Then evaluate just how many to make -return on investment. Is there a huge market for them? Probably not. As far as a drawing, I merely suggested you look at the exploded view of the front mount distributor in the MPC as it shows it, gives the original part number, and then you can look it up further for the detailed part description. P/N 91A-12159 shown as: 8-32 x .31"L BRASS FILLISTER HEAD SCREW. Now, the McMaster-Carr part (SEE LINK) is 3/8" long but a 1/16" extra length won't hurt a thing as there are no close interference parts it can hit. Remember, Henry Ford and Henry Ferguson both insisted that all bolt and stud lengths have no more than two threads protruding on them when the nut was fastened so everything was designed to the nearest fractional size. You can get the screw part sketch at the LINK I provided as they show all the dimensions. Do you see my point?

  • I don't know why this outfit is never mentioned?
    Maybe I will start a firestorm of comments?
    I buy nearly everything I need from this outfit.
    I see they have the complete breaker plate assembly.

  • Re: Need help finding distributor parts
  • Well, first of all, YT is not a real parts supplier. They rely on sponsors and advertisers who donate to their site. Thus there are many parts suppliers/vendors there, and they will ship you whatever/whomever is available. Next, many years ago I bought something from them, I won't say which vendor in particular, but it was thru YTMAG, and I received the wrong item. They wouldn't rectify the problem and so I never went back to their site again for parts. It was very soon after that I discovered Just8Ns and Dennis Carpenter anyway. There are many Ford Tractor suppliers out there and most usually sell the standard TISCO parts plus most, if not all, sell the Dennis Carpenter licensed-by-Ford parts he reproduces, almost always at a hefty percentage markup. There are also many suppliers who 'make' some Ford Tractor parts that are just plain junk. It does matter who and where you buy from. My opinion so your mileage may vary...

  • Re: Need help finding distributor parts
  • No offense to YT, but every new breaker plate I've seen is pot metal. It will wallow out at the screw holes in no time at all. And none had the oem concave head brass screw either.


    Best to rebuild what you have or buy a used one & rebuild that one.

  • Re: Need help finding distributor parts
  • '91A' is the FORD part prefix code for 1939 models. When a part was used across different modules, it retained the same part number. That's why you'll find a few '9N' prefixed parts used on the Hundred Series tractors.

  • Re: Need help finding distributor parts
  • The parts I need are not listed in my parts catalog or their website so I figure I need to get them from a supplier. Tried McMaster Carr and a few others but no luck yet.

  • Re: Need help finding distributor parts
  • The heck with net catalogs no one can possibly illustrate everything they stock. Most rarely update and when they do it is hit and miss. I know Just 8N's has unusual distributor parts, I have got some in the past from them. Speak of the net, I just spent half a day looking for a certain mower rim all over the net to no avail. Called a Texas Mower Parts and told them what I needed, guy says Oh, the 4" one with a 2" center opening and slotted valve stem opening. How many do you need? Never rely totally on puters, they never ever will equal a knowledgeable parts man or anyone else for that matter. Call first, then browse.

  • Re: Need help finding distributor parts
  • Dan-
    I found all the parts at McMaster-Carr that will work. 8-32 x 3/8 Fillister Head Bras Screw at McMaster-Carr -SEE the LINK. The extra length won't hurt anything. Also, links to the brass washer and flat external tooth washer listed as well. The latter says thickness may vary from .025" to .039". Part spec shows thickness at .020". I really doubt the thickness will matter that much, especially if using the 3/8 long screw, but if so you can always hit them on your surface grinder. Since packages are in quantities of 100 pieces, maybe I will buy some of each from you.

    BRASS WASHER:

  • Dan-
    I have an old distributor I can give to you when I come back down in a few weeks. The unit is trash, timing tang inserted 180 off and busted the housing, but all other parts are salvageable. It is the original distributor I've had for a long time now and was the first time I did a tune up...hence the broken tang. I don't throw anything away...really. If you need it sooner i can mail it...

  • Re: Need help finding distributor parts
  • The 91A12159, Condenser Contact Screw, shows that it uses two washers - a) p/n 34938-S, washer No. 8 - external tooth; and b) p/n 351260-S washer - .187 I.D. x .31 O.D x .02 thick-plain-brass. I will look at my spare parts distributor but the MPC doesn't list the actual 91A12159 screw size and my scan of the original Standard & Special Parts & Hardware manual is no longer here in MANUALS. I'd say it is a #8 screw, brass, possibly a fillister head,length unknown, but if I scale it at 5/16 long. "91A" prefixed part numbers means they were used on prior Ford models so are in the system pipeline elsewhere. I will check my vehicle chassis manuals for the exact specifications. McMaster-Carr should have all the parts, or relatively close facsimiles. I just placed a $65 order on Friday at 1630 EST, and on Saturday I received a partial shipment...talk about FAST DELIVERY!!! When I got home from your place there was a package for me from them waiting ...WOW!!!

  • Re: Need help finding distributor parts
  • After looking at the picture I guess I should explain.

    The brass screw at the top that the coil spring contacts is missing.

    The nylon/plastic insulator is also missing.

    The eccentric screw that you adjust the points with is also missing. I know the screw is "braded" but if I can get a new or good one I can replace it and brad it back in. Easier than buying a new plate.
