  • Ford 2N Starter
  • Iíve just received a new starter motor for my 2N and the bendex is completely different. It works but slowly turning it over on the handle I can hear what I think is contact somewhere. Anyone had this problem before? Shafts are same length but the gear is longer and the spring is not there on the new one.

  • You have a positive drive bendix.

    And if you keep turning it, it will lock in the extended position and it will then be very difficult to install.

    Most new and rebuilt starters come w/ a rubber band around the shaft to prevent curious owners from doing what you just did.

  • Thanks Bruce. Could I swap the bendex from the old starter to the new?

  • Sure.....but why? Are you aware of the advantages of the positive drive?

  • Am I understanding correctly that would involve changing it to a negative ground setup? Iím trying to keep as original as possible as it is the rarer 2NAN with the TVO setup.

  • battery polarity has nothing to do with the bendix on your starter.

    It works like this......the bendix engages the ring gear on the flywheel & turns the engine over. When the engine speed exceeds the design speed of the bendix (because the engine is running) it disengages. (and I can never remember what RPM that is) All the new style positive drive bendix does is allow a higher engine speed before it disengages.

    So how does any of that deal with battery polarity?

  • Iím very sorry Bruce, I misread your comment. I understand what you are saying.

    As per my original comment just to explain, the starter motor is installed on the tractor but I didnít trust the positive drive bendex as it looked vastly different from the original but went in okay. I kept the battery disconnected and slowly wound the engine by the hand crank at the front before I started breaking either the flywheel or starter motor on the starter button.

    When I do this, I hear some slight contact and I am worried that this fouling somewhere so my question is if the bendex is suitable for this tractor.

    Again, sorry for any confusion.

  • w/o seeing it, I can't say for sure if it is ok.....but, the fact that it went in ok tells me that it will work. if it is not 100% seated on the rear of the shaft, it could be making some contact w/ the ring gear.

    hook it up and press the starter button. worse case, you break the bendix.
