  • Yes, Chris, I concur with Kirk. It looks identical to my late '39 (NOV) s/n *9N-653I* model as shown in the pix below -the blue one. If you are just looking for a used original diffy case to replace you busted one, I know of a 9N parts tractor near me that would work for you. You know my contact info...

  • HiYa Chris-
    Iím unsure on the dates, but there were some very early models that the rear end top link boss was added on as a separate piece. The foundry then had new patterns made where the boss was cast onto the rear case all in one. You can tell by the sharp corners on the early one and on the smooth blended radii on the later ones. Here are some pix. My late 1939 *9N-653I* rear end the blue one. Hope this helps.

  • Good morning Chris,
    There were three different center housings used by 1940. It mostly had to do with beefing up the top link area. I don't remember your serial # on your '39 but believe it was a later one which would have one like the center photo. I don't think any more changes were made after the 1940 model until the 8n model.

    later '39 housing

    1940 housing
