  • 8N Ford Tractor Lower Link
  • Dear Sirs,
    I found a NOS lower link for sale. The part number stamped on it is 9N559.
    The Parts List Manual shows that, for 8N tractors, the part numbers is 9N555(R) and 9N556 (L).
    Is it for 8N tractors?
    Which will be the difference between 9N559 and 9N555/556?
    Thanks.
    Carlos Pizzi

  • That is the link part casting number only. 555 & 556 are the entire assemblies and are all correct. You never have the assembly number cast on a part. If you find a 9N, 2N, or 8N prefix, it is only the part casting number. FORD nomenclature defines the part prefix as which module the part was fist used on. Examples: 9N-555 and 9N-556. If a an alternate supplier was used, or a minor change made, a part suffix would indicate by letter, i.e., A, B, C. If a major change was made to the part, for example from the 2N-10000 generator to the 8N-10000 generator, then a new prefix code was released with it for the new part. Basic part groups were all standardized. 10000 block was generators, 17000 block was tools -follow? Yes, if part is cast with original number, it is the real McCoy and not a repoop.

  • Is there any important difference between the right and the left lower links?

  • I was trying to picture the arms as I'm 6/7 miles away from the farm but thought about the linch pin holders being the only difference. I don't believe the arms are different lengths. The early 9N linch pin holders are mounted vertically and were changed at some point to the horizontally mounted clips. Seems one would only have to flip one over for one side, but will have to look at my early 9N and early 8N next time I'm at the farm. I don't believe the arms are different lengths; that doesn't seem practical. The distance from link under axles where the arms attach to the ball sockets on the end of arms is equal, somewhere like 31-1/2" or so, I think. Dimensions are always measured from centerline to centerline. Further proof can be evidenced by the optional stabilizer bars. The bars are identical; there is no LH or RH part, can be used on either side, and hole dimensions also equal on each. If one has bent, cracked, and/or welded lift arms, chances are someone installed stabilizer bars incorrectly. We have a document in our How-To's on the correct procedure for installing stabilizer bars -it matters. NOTE: There is a huge difference between STAY BARS, which are included with each new tractor in the parts shipping kit, and STABILIZER BARS. Stabilizer Bars are sometimes called 'SWAY BARS' because their intent is to prevent/limit side to side motion of the 3-pt lift arms and the implement attached. They were originally released as for use with the Dearborn Rear Attached Mower, and then realized they could be used on any implement that needed stable tracking. They work great when using Finish Mowers, Brush Hogs, and back blades for snow plowing. STAY BARS, a different animal altogether, are used when pulling an implement and attach from the top link rocker to the lift arm ball sockets/11-hole drawbar pins. The nominal height is 18" perpendicular from ground level to drawbar top surface. The STAY BARS keep that position locked in, and you use the OEM kit included SAFTEY WARNING LOCKOUT BADGE & CHAIN ASSEMBLY to clip onto the touch control so you DON'T accidentally try to raise the 3-pt and break things. The STAY BARS are typically used with the Dearborn Swinging Drawbar. Here is a typical Stay Bar setup:

  • The arms without the linch pin clip are symmetrical front to rear. What makes them right or left is where the clip is welded on near the rear ball, always on the outside of the link.

  • Re: 8N Ford Tractor Lower Link
  • Yes there is a difference. Measure the distance between the lift arm pins in the asle trumpets and the distance between the lift points across Ford/Dearborn implements.
    The difference is compensated by a slight "S" curve in the lift arm. There is also a welded loop on the arms near the implement end to place the clips to lock the arms to an implement.
    I have seen bent, welded and mis-aligned lift arms on some of the tractors that I have owned. For the best results using a 3 point implement, have the right setup.

  • Re: 8N Ford Tractor Lower Link
  • Yep, otherwise they wouldn't have a LH and a RH but a good question.

  • That part number[9n559] is for just the ball end, not the complete arm, which is the part number you state as 9n555.Lots of parts are made of more than one sub-assy. Then combined into a final part and number. don b

    This is a quote from Don B on YT about 10 years ago.
