  • 9N-1108
  • I have been going through my part manuals and retyping all the part numbers and information into an excel file. This will allow me to sort the list and see when changes were made or when parts where obsoleted.

    Then I ran into the rear wheel and had to stop and study this for a while. The 7x 32 rim was marked as obsolete in Aug '39 and replaced with a 8x32 rim and goes back to 7x32 in 1949. It does not appear in any books after that. The 10x28 rims started out being an option,then in '49 they became 9x28 with the same part number as the 10x28.

    The steel wheels that appear on war time 2N's do not appear until the 1949 parts catalog.

    This is way to much fun LOL.

  • What happened to the 1108-B Rim? The LOOP Rim would be the 7 x 32 style. The 1108-C Rim & Band Ass'y is the 8 x 32 Hat Rim. The 1108-D would be the 9 x 32. Why the earlier unit at 10 x 28 is the same is unclear. The steel wheels are shown in the JAN 1946 MPC and the July 47 MPC. Ass'y 9N-1170. Why not listed earlier maybe due to them being options in accessory catalogs. Remember that steel wheels were used on tractors long before rubber was introduced. The 9N steel wheels were optional before standard on the 2N WarHorse model. What we need are the EI data sheets with the Kelsey-Hayes drawings.

  • The drawing for 9N-1108-C says it is the 32 x 7.00 hat section rim and band assy. Not sure what a 8 x 32 is.

  • What year is that drawing? Could you send me a copy of it? Looks like some thing changed between 46 and 49, was it the rim or the way they measure it?.

  • I see no mention of an 1108-B or 1108-E. There also is no mention of a 9x32 rim. I do not have a 1946 or 1947 MPC. It will be a couple more hours of work before I get to part number 1170. If any body has an extra copy of those and wants to donate to my work I would appreciate it and return it when done. I have tried to get the "drawings book" but no body wants to sell theirs.

  • Re: 9N-1108
  • Dan -we do have the JAN 1946 MPC in our MANUALS forum, under PARTS. I will send you a pdf of my July, 1947 MPC. I need to copy my May, 1950 MPC soon as well. That is the important one with many 8N changes being listed -Proofmeter, Side Mount Dist; New genny, new Steering Box, and more.

    On the 1108-A drawing, the 7" is shown as measured on the inside of rim. Randy, is the 1108-C Hat Rim shown at 8" on its drawing? Also, there has always been talk that the rims were zinc plated, cadmium plated, and even painted. The 9N-1108-A loop rim drawing has a note "PAINT - SEE SPECIFICATION". It's probable the spec says paint was optional. However, none of these would constitute a separate drawing revision to be issued. Also, and I know you haven’t gotten that far yet, but there seems to have been two early 32” center discs, p/n 9N-1122. Some have two sets of bolt patterns on them –see picture. The March, 1940 MPC lists the 9N-1122-D as the 32 x 8 center and the 9N-122-E as the 10 x 28 center. What were and what happened to the “A”, “B”, and “C” rev’s?

  • On the early loop rim wheel centers 9N-1122, one set of holes measure 28-1/4" on center and the second set of holes measure 28" on center. The loop rims bolt onto the 28-1/4" hole pattern. Also the overall diameter of this wheel center is 29-3/8", where as the wheel centers for the hat rims measure 29-1/2".

  • Re: 9N-1108
  • FWIW: The original drawing for the 9N-1108-A 'Loop' Rim shows the lugs/loops on a 28" B.C. (Bolt Circle). I'm sure the 9N-1122-A Center Disc would show the same.

  • Re: 9N-1108
  • Thanks, Joel. I know we discussed this topic some time ago. The $10,000 question is what was the REV level? "B" is my guess. I say the "A" REV only had one set of holes for the 32" loop rims. It seems to me we also discussed that there was a 28" loop rim as well. I may be wrong, but I surmise the 9N-1108-B Rim was the 9" x 28" version and the center disc, 9N-1122-B had the dual bolt hole pattern. Both would be declared obsolete upon release of their "C" revisions.

    By the way, I enjoyed Brent McLeod's and your article in the latest issue of the Ford/Fordson Journal, Winter 2018, Volume 25, Issue 4 on restoring early 9N's.

  • Re: 9N-1108
  • Rev B would be my guess as well because I have seen a copy of the "Invitation to the Land", dated june 29, 1939, and it shows many pictures of the 9N tractor, all with 32" Loops and the wheel centers only have 6 holes in them. The loops themselves have an elongated bolt hole, so it would actually fit either both 28" or 28-1/4" bolt hole pattern. Both of my tractors when acquired (1960's and 2016) had the loops on the 28-1/4" pattern, and I believe this is true due to the wear on the wheel centers. My third set of loops came with wheel centers and they were also mounted on the 28-1/4" pattern.
    thanks for the kind words on the articles - I cant wait to see Brett's '39 tractor all complete

  • I'm confused
  • I generally take a look around the internet every weekend for parts books that I am missing and have not found any recently. You keep calling them an MPC but as far as I can tell the first MPC came out in 1952. Am I missing that many? Here is what I have:

  • Re: I'm confused
  • MPC's/Parts Book, Price Lists -seems all the same, wording is relative. Maybe it was John Smith who coined the phrase for all of the parts books as Master Parts Catalogues. The JAN, '46 issue says "PARTS BOOK". The July, 1947 issue, this is the very first 8N parts book, has "Parts Catalogue". ALL of them list the parts in sequential order. You gettin' cornfused yet???? Wait till you get to the SEP '52 MPC. It only lists the 9N-1108-D Rim. then, scroll down and it lists "9N-1122-D Disc (rear wheel)- 32" x 7" - used with 9N-1108-F". Huh? The 7 x 32 rim was no longer supplied, but the center disc was??? Ya gotta remember that when a new part was released, the earlier prior versions were usually obsolete. Supplying early 32 rims probably went on for some time, but when the 9" x 28" hat rim became the standard, any and all previous versions were declared obsolete and disappeared, or as stated, "No Longer Serviced" in the part books.

  • Re: 9N-1108
  • My bad -28 x 9 is the Hat Rim for the 10 x 28 tire, now numbered 11.2 x 28. I should have left you all my hard copies. Should've said something. the "F" and "G" appear to be steel wheel -'less lugs' makes me think so.
