  • Alternator
  • How do you choose an alternator for a 1950-52 8N? I recently acquired this tractor that has been converted but the alternator was missing.

  • Guessing if the alternator is missing so is the pulley for the alternator. If you buy an alternator from an auto parts store it will no doubt come with a pulley for a 1/2" belt. You will need to change that to a belt for a 5/8" belt. One source for a proper pulley is https://www.yesterdaystractors.com/Ford-8N_Alternator-Pulley_AFD5035.html

  • Go to your local auto parts store and get the cheapest Delco internal regulated alternator you can get for an early 80's GM product. 9 o'clock orientation on the edge plug for the front mount distributor (goes on right side), 3 o'clock orientation for the side mount distributor (goes on left side). That way the plug goes toward the engine and won't get bumped or broken as easily.

    You can change orientation if you are careful. Any one of the amp ratings will work

  • Most alt conversions are GM 10si Alternators.
    Cheapest one of those falls off a '79 Chevy caprice, if memory serves.
    That particular unit kicks out about 30 amps, more than enough for your tractor.
    Rockauto might be your friend for that one.
    JMOR has wiring diagrams to get it hooked up correctly.
