  • Bendix keeps breaking
  • Hello, I just got a new (old) ford 650. It is my first tractor and I am very excited to have it. But I am a complete amateur, so I am also very excited to be a part of this club. Good news is that I bought it off my friend and neighbor who has taken good care of it over the years. Anyway, the bendix was bad when I bought it, so we put on a new one and it cranked perfectly… for 4 days. Then it got stuck just like the one in the picture in the 3/8/20 thread (http://www.ntractorclub.com/forums/nboard/messages/252543.html). We tried to unlock it with the screw driver and wire brush and it didn’t budge. The tractor has been converted to 12V for some time. Will the Denso starter that TheOldHokie pointed us to (http://www.autoelec.com/html/ford_2n-8n-_9n.html) likely solve the problem? $250 is pricey but I’d like to nip the problem in the bud. Thanks!

  • A 12 volt conversion adds sudden shock to the flywheel when the bendix engages the ring gear. Many conversions have worked for years without problem. However, you may have a broken gear tooth on the flywheel that locks the bendix. Pull the stater and roll the engine by hand with a crank while looking into the cavity at the flywheel.

  • Thank you for the response! Is there anyway for me to somehow convert the power back to 6V going to the starter without having to do a total rewire?

  • Yes, converting back to the OEM 6V/POS GRN setup is doable providing you have all the correct components -generator, voltage regulator, battery, wiring et al. Shortcuts are not an option. Are you certain you are using the correct starter Bendix? Are you certain your 12V setup is wired correctly? I'd verify what you have now is correct before making any changes. I suspect something else is wrong.

  • Dumb fingers: pull the starter, NOT a stater.

  • We are knocking over a hornet's nest with this issue (lotta' opposing opinions that vary).

    I can point you towards forums where "reportedly" great success was achieved with this issue, by using part of a broken spring as a wire resistor, to knock battery voltage level down to starter somewhat, from 12 volts, down to something more agreeable for some (persnickety) 6 volt starters.

    What was reportedly used in the forums was basically broken starter Bendix Springs. Do you have any nice stout fencing wire laying around? Five or thereabouts wraps of this heavy wire around a wooden dowel to form resistor would be a good starting (lol) point :-) Sorry, no can give any specs on how many turns of what diameter or what kind of wire to use, I've not experimented personally myself.

    You didn't hear it from me! (for reasons which escape me, some folks take umbrage and get hot under the collar when discussing this peculiar topic) Ford Man VS Chevy man LOL

    imho, experimenting's worth a shot before spending $ for one of those really nice, newfangled starters. Forum URL poster "Royce in Dallas TX" claims success with: "Bendix Spring is a very effective current limiter, as is a 12 foot #2 gage wire."

  • I have heard of people replaceing the battery with a small 12 volt lawn tractor battery. Not as much kick power . They said it started well and ended their breaking problem.I myself have not tryed it.

  • If you'll use a regular 12V starter it will turn slower than a 6V starter in a 12V system.
