  • 9N-Hydrulics/PTO fluid
  • I have a 9N, I believe it is a 1945-47,not sure, I am told by some that the
    transmission and PTO compartment are all together, not separate. From some of the
    info I have gleaned from various sites and people, it takes approx 22 qts of fluid
    that will fill the compartment and feed both systems. I have only found 1 think 3
    places to drain and only one place to fill. Just want to confirm the info I have,

  • Re: 9N-Hydrulics/PTO fluid
  • Yes, you are correct, sir. ALL 9Ns and 2Ns have a 3-speed transmission and NO POSITION CONTROL for the hydraulics. There are three drain ports on the underside of tractor -always start with small square head NPT plug on the diffy case. Move forward as you drain each port. Be aware that a fourth drain is the engine oil drain port on the bottom of the engine oil pan -do not remove it. See this document from HOW-TO's for reference only. Page 9 has the drain procedure. Be aware that the 9N/2N hydraulic systems had differences. The filler port is on top of the shifter cover. Capacity is 5 gallons, but do not ever put that much in at one time. Start with 3 or 4 gallons.

    Fill with GL-1 SAE 90 Gear Oil:

  • HiYa Jim-
    There are several other members here with much knowledge on these old N's, some with a lot more experience and knowledge than I, and that is why we are here -to help newbies like yourself. We all were in your shoes at some point so sharing and helping just comes with the territory. One of the beautiful aspects of these old Fords is that there is always something new to learn. We have a wealth of information offered here in additional forums. Our HOW-TO's holds many self-help, Do-It-Yourself projects and our MANUALS forum contains scans of many od the original manuals on parts, tractors, implements, and other related subjects and it doesn't cost anything to download any or all if you like. Best to create a new folder on your desktop to save it all in for handy reference. Some fellows have taken the time to put together some valuable technical information documents that are every bit as useful as any wrench. One is Bruce(VA)'s "75 Tips for N Owners" and another is "WIRING PICTOGRAMS by JMOR". Download copies and put in a binder that you can take to the barn or tractor shed when you need to work on your tractor. If you don't already have the essential manuals, get them and read religiously. We have some like an older version of the I&T F-04 Manual and most MPC's - Master Parts Catalogs. There is also John Smiths’ now archived web site with a lot of the history and timeline factors of the N-SERIES tractor –see LINK below. Before you start buying a bunch of new parts and just replacing them, get yourself the manuals and know about the safety and operating issues prior to turning the key. Have fun but be safe!
