  • 1942 9n
  • I think I found out why my 9n has a non standard generator
    It appears to be a Model A generator
    will it hurt to leave as is or should I replace with what is supposed to be there
    Thank you for any advice

  • Here is an early Ford V8 (1932) generator with the cutout attached. Rating: 12 AMPS/6.7 VOLT output. In 1934 the 3rd Brush was increased to 19 AMPS at 7V output. The FORD Model 'B' auto used the carryover Model 'A' 3-Brush generator with round-can cutout, rated at 12 AMP/6.25 Volt output. In May, 1937, the generator was changed to a 2-Brush/2-Wire unit and now used a voltage regulator, obsoleting the cutout. The FORD 9N tractor first used a variation of this genny and VR.

  • The model a generator put out 7.5 volts just like your 9N generator except the model a generator has the cut out on top of it. I'd leave it alone as long as it works

  • Not 100% certain on this Bruce, but didn't the Model A genny pulley use a 1/2" belt and the N's used a 5/8" belt? Most Model A's and early V8 vehicles I see at shows have all been converted to 12 Volts so I can't determine. Also, pulley diameters were different on both Model A and early V8s.

  • I was having one heck of a time trying to ID that generator
    and yes it had a cut out on it
    I tried to explain it the best I could but left a few here still guessing
    Just happened on it while searching for more information
    I will try and work with it but am not having the best of luck

  • Synder's is the go-to source for Model A parts.
