  • Golden Jubilee
  • I recently traded a Farmall M for a NAA (swapped by pictures...hadn't seen it up front before we traded). I checked the serial number (NAA35058) and figured out it was a 1953 Golden Jubilee. There is what appears to be a diamond shape after the last digit. Anyone know what that pertains to?

  • You are a brave, trustworthy soul -making a deal by pictures alone! Someone you know? Anyway, FORD marked their engine blocks on ALL vehicles, beginning with the Model A, maybe sooner, and not just tractors as some assume, with a hand-stamped serial number after the engine passed a break-in/test procedure at QC Inspection. On the 9N, 2N, and early 8N models, a STAR (*) symbol was used before and after the serial number to designate steel cylinder liners (sleeves) were used. In mid-1951 (during the 8N production run) FORD then introduced cast iron cylinder liners on all vehicles, obsoleting the steel liners, and thus the new designation was the Diamond (<>) symbol. This practice has made me always wonder why they had to mark engine blocks like that. They must have had some inkling that they would be changing from steel to cast iron at some point. It is also a good idea to never buy engine kits/parts prior to tearing down your engine to see exactly what is in there. Since steel cylinder liners are no longer made, all that is available are the cast iron sleeves today. All blocks marked with the star symbols really is a moot point. Chances are good the engine has been serviced at least once in its lifetime and anything could be in there. that includes no sleeves at all. Some opted to bore out their cylinders for the larger Mercury pistons. Plus, some liners have a .040 wall thickness, and some have a .090 wall thickness. As stated already, there will be a diamond symbol before and after the serial number so look again closer and you should see the one before the number. Imagine you were the guy who had to stamp serial numbers. Each letter, each number, each character, all day, 8-9 hour days, six days a week. By the end of your shift, possibly sooner, your arms and hands are probably fatigued enough that holding each stamp in place was not easy and thus could explain why so many serial numbers are weak and hard to read. Here's a LINK to the archived John Smith site so scroll down to read about the NAA model.

  • Tim,

    In your response, you say, "Since steel cylinder liners are no longer made...." The thin 0.040" sleeves were steel and the thick 0.090" were cast. For clarification, the thin 0.040" sleeves are still available today for the 8N/9N/2N along with the thick. And as far as I know, the NAA only used one sleeve thickness.

    Cool number stamping ad.

  • There probably s a diamond stamped in front of the serial number also, but since individually hand stamped, probably not very visible. This diamond indicated a cast sleeved engine

  • Well, clearly you have the rare Diamond Jubilee! ;)

    It tells you what sleeves it had installed at the factory. Steel, I think, but I can't find my link to John Smith's website to confirm that.

    Anyone got the link handy? I'm pretty sure it's on this site, but I can't find it.

  • New URL is http://fordtractorcollectors.com/oldfordtractors/. If that is temporary or permanent I don't know, but www.oldfordttractors.com redirects there, and the site is complete, not missing images like the web archive.

  • Bruce,

    I appreciate it. I have owned 2 8Ns and a 2N, but no Jubilee before...just getting familiar with what they are about. I have been trading around with the N's, but might keep this one.
