  • What do we have?
  • Howdy! I am a hobbyist farmer in Southern Indiana and recently purchased a tractor that was sold to me as a 9N. Well, looking at it, there seems to be parts from a 9N and a 2N. Could y'all, the experts, take a peek at the photos and tell me what it is I actually have? The motor appears to be a 9N, but the first part of the stamp is worn off. It does appear that you can just make out a 9 and the letter N. The rest of the stamp does match up with a 1941, I believe. The rear axle has a 2N stamp. Thoughts? Thanks!

  • Re: What do we have?
  • The 9N after s/n 12500 up thru the '46 2N were pretty much the same beast so unless you had an early 9N to restore all original it ain't nuthin' to worry about. Important facts are: front mount distributor, 6V/POS GRN or 12V/NEG System, and you are all basically set as everything else same. ALL 9N and 2N tractors used the "9N" prefix in the serial number -there is no such thing as a '2N' stamped prefix s/n. Parts however would carry a 9N or 2N prefix but only when changed as a different revised part. For example the 2N-10000 generator was redesigned and was different than the 9N-10000-C generator. You'll have to do some homework on Ford UPC system to understand all that -the archives are a good place to find that out. That means your tractor could have a 9N part and prefix if it never went thru a revamp. Some Hundred Series tractors still have 9N parts on them. Best thing is to invest in the essential manuals and read real good. We have many D-I-Y articles and informative documents here in HOW-TO"s you can download as well. Forget the s/n, worry about your electrical system for starters. OEM Fords were 6V/POS GRN. A lot got switched over to 12V by fellas so it is very important to know what you have and how it is supposed to be wired. WIRING PICTOGRAMS BY JMOR from HOW-TO's is important. The I&T FO-4 Manual, and the 39-53 MPC are important tools. The 9N/2N Service Manual is a very detailed manual as well. The latter is also in our MANUALS forum -CLICK ON TEH LINK AT BOTTOM.

  • Re: What do we have?
  • Thanks so much for your response! We bought her and she definitely wasn’t running. I rewired the ignition and charging system and did general carb and fuel system maintenance and she fired right up. It has a 12V alternator and still has the resistor and 6V coil. I plan on fully converting it and bringing it back close to OE as far as parts and appearance, charging system aside. My confusion and interest is piqued more from the 2N stamp on the rear axle.

  • Re: What do we have?
  • Ok, 12V but what and how did you rewire the charging system? There are but 2 or 3 correct ways and a zillion incorrect ways. 12V battery, 12V alternator, round-can cutout and generator removed altogether, OEM ballast resistor wired OEM, 6V coil on a 12V switch out requires adding an external ceramic 1-OHM resistor. Using a 12V coil (recommended) eliminates that extra part. Starter motor is 1-Wire unit with NO solenoid. Ignition Key Switch is 2-wire OEM, starter neutral safety button switch by shifter, an ammeter, and wired all correctly will have you running. Tune-up on distributor can’t hurt. Parts best to get at NAPA:

    POINTS: Echlin, CS-35, or Blue Streak – FD-6769X
    CAP: FA-350 or FD-126
    ROTOR: FA-300 or FD-104
    CONDENSER: FA-200 or FD-71
    GASKET KIT: SK 60308 or BK 60308
    SPARK PLUGS: AutoLite 437 (also 216) or CHAMPION H12 (also 512)
    POINT GAP = .015”
    PLUG GAP = .025”
    FIRING ORDER 1, 2, 4, 3 CCW.

  • You have a mutt "41 engine. 2N radius rods earlier dash. Parts get switched around quite a bit on these old tractors.
