  • Long pin pics/8N vs. Fergy
  • There was an earlier discussion about the early 8N having the long pin that runs thru the lugs(cast into the top of the diffy)& the hollow toplink yoke pin. On the later 8N's the long pin was gone(due to the lawsuit?), but the lugs are still there. Were the lugs gone by the time the NAA started production? I know there are none on the hundred-series.

    Here's a pic to compare the pins Ford made(w/the groove)& Ferguson made(hinged).

  • I know this thread is way old, but I thought I'd chime in since no one addressed your question about the differential lugs on the NAA. I currently have a '53 Jubilee (NAA0929) on the property and a '54 NAA center section and trans (NAA117312). Both have the lugs.

  • Re: Long pin pics/8N vs. Fergy
  • Jim...thanks for following up. If the Jub & NAA both have the lugs it makes me wonder if they have the same diffy housing as the 8N. According to some of the posts below, Ford discontinued the longpin in 1949, so there was no reason to keep the lugs in the casting designs. Unless they already had the casting dies made by the time the legal stuff was settled.

  • Re: Long pin pics/8N vs. Fergy
  • That question is a complete mystery. The center section is definitely NOT the same as the 8N. I have both an 8N rear section and an NAA center section laying around. The biggest difference is the 8N casting has a big square hole in the bottom where the hydraulic pump goes. The NAA just has a 3/4" (estimate) drain plug in a solid cast iron bottom. The right inspection plate on the NAA is smaller and held on with just 4 bolts. The 8N inspection plate is larger and has 6 bolts to hold it on. So why keep the lugs? Some things just can't be explained!

  • Re: Long pin pics/8N vs. Fergy
  • Yes, the dimension given at 9 7/8 is from the flange of the head to the other end. Overall it is 10.62 after March of 1948 and was a sixteenth longer (10.68) for a while in early '48 (released in 1/47). How many were made in that time is unknown. There is a section of 1 inch diameter right up near the flange. It was originally cadmium plated or zinc, and after 1/48 cad spec was removed.

  • Re: Long pin pics/8N vs. Fergy
  • Still not able to find any information on that long pin. Now that I have an 8N center housing I have to ask "what is the long pin for?" Can you send me the dimensions so that I can make my self one? Do I even need one?

    Thanks

  • Re: Long pin pics/8N vs. Fergy
  • Hey Dan....not many Dearborn implements used the long pin, but Ferguson used it for several non-draft implements. They used it to take tongue weight off the toplink rocker. Those implements that were designed for it had a special link w/ a wide-set yoke.

    I'm going to post a pic here of a replica(I fabricated last year)of the Ferguson pick-up hitch. It uses the tractor's lift links to raise & lower a hitch hook mounted under the diffy. The upper yoke link telescopes & locks(in the up position)w/ a hitchpin. As you can see it is attached at the long pin, so there is no tongue load on the tractor's toplink rocker. I won't go into the other purposes of the hitch since it's off your topic, but let me know if you want more info.

    If we have to, I'll burn a CD w/ pics & such, & mail it to you. If this attached pic opens for you, I'll post the pin pics again, too.

    Jeff

  • Re: Long pin where did they all go
  • I finally have a use for one of these "Long Pins" but can't find any of them. Would you happen to now where one is for sale? I've checked with Just8N's and YT mag and ebay.

    Thanks

  • Re: Long pin where did they all go
  • Dan...I see them come up on ebay once in a while, but very pricey. All Ferguson tractors & Massey-Ferguson tractors up thru the 100-series(mid-1970's)had one from the factory. You could probably get one pretty cheap from a boneyard, if you're patient. I'll keep an eye out for one.

    What did you get to hang off of it?

  • Hey Dan:

    Did the parts show up for the 9N's rear end?

    See if the pic shows this time:

  • Re: Long pin pics/8N vs. Fergy
  • Nope. Still checking everyday for an 8N housing. Not sure what happened maybe the easter holidays slowed the mail down.

    Pics of the long pin didn't show up.

  • Re: Long pin pics/8N vs. Fergy
  • Jeff...I think both are Ferguson pins.I think Ferguson changed to the "hinge" type later.The solid pin was 8n486A which was discontinued at serial number 237336 execpt for replacement in tractors below serial number 237337.The hinged type is still available. don b

  • Hey Don:

    Not sure I understand why the grooved pin would be considered a Ferguson part when it has a Ford part # & is shown in the 1947 TPC.

    Or are you saying the legal settlement made it a Ferguson part to be discontinued by Ford(as detailed by your earlier notes)?

  • Re: Long pin pics/8N vs. Fergy
  • Jeff...Ford didn't care much for patents.Ferguson took several Ford drawings to England and had them patented over there under his name.However,Ford agreed that the "pin" was Ferguson's idea,[for his wagon] and agreed to stop using it in production after 8n 237336 until 1966.Of course we all know the pin was almost worthless, so no big deal.
    Ferguson modified the pin to make it a hinged pin [for the TO-20]and the Ferguson part number became 181-060-M91 and is still available today. don b

  • Hey Don,
    Did you see the post that directs to this US patent for the long pin?

  • Re: Long pin pics/8N vs. Fergy
  • This is what I found about the long pin and patents.
    The pin idea is patented by Ferguson under number: US2486257
    The pin is filed at nov 2, 1945. The patent is granted at Oct 25, 1949.
    About time also the long pin was removed from the ford tractor.

  • Re: Long pin pics/8N vs. Fergy
  • Thanks Don. Your post reminds me you've mentioned before how the long pin was designed for the wagon. I can't imagine it was the pull-point for a wagon or trailer, so was it some kind of toplink hook-up for transfering weight to the tractor? If so, it must have been quite a contraption.
