    Pulled the Lift Top. Problem was not elusive! Broken D4NN-545-A Arm, Hydraulic Lift Ram. Now I'll be in the market for one of those.

    Thank you to those who responded.

  • I don't know where you got that p/n prefix, but it is either a '9N' or an '8N' -two different parts and no they don't interchange. The 9N-526 Ram Rod fastens to the 545 ram arm shaft a clevis pin and cotter pin fastener. I don't know what the differences are, but something changed which would indicate they do not interchange. If a part was used on different modules without any revisions being made, it would retain the original part prefix that it was first used on. For example, the exhaust manifold is p/n 9N-9425. It never changed so is used on the 9N, 2N, and 8N and listed as such in the MPC's. The July, 1947 MPC, the first parts book for the 8N, lists both the 9N-545 arm and an 8N-545 arm and the modules used on. You can go to our MANUALS forum and look at the MPC's yourself, even download a copy to your PC or save it in a folder. I'm also curious as to how you broke yours. That's a pretty beefy part to simply just break, unless there was something else seriously wrong. Can you post pictures? As for a replacement part, you may have to get a whole used 9N top cover with cylinder and parts included in order to find one. I don't think anyone repops just the arm. Try the usual on-line auction sites, our ADS forum, and your local boneyard. Someone may have just a top cover they'd be willing to part with too. If so, it may easier to just replace the entire top cover with lift and cylinder attached than trying to just replace the arm. Either way, I suggest since you have the cover already off, go ahead and replace the cylinder, piston, and O-Ring and avoid any hiccups later on. You may possibly could also drop the pump and do a complete cleaning/rebuild on it. How mucky was the oil? At least clean the valve chambers and install a new safety relief valve.

  • Thank you Tim,

    We were actually hoping to find someone who knew WHY they do not interchange.

    On line suppliers only list the 8N version however they list it as fitting the 9N and the 2N also.

    Finding a replacement top is not a problem. My nephew is parting out a 2N and has the top complete. The problem is the weight of the monster and my age. Logistics of making the switch is a problem.

    I do not have the capability of posting pictures here at the farm. Will take several and post them later this coming week.

    Part Number I listed came from the FORD NEW HOLLAND PARTS CATALOG, Reproduction license issued 3-1-94.

    Not the first error I've found in that catalog.

  • Hi Jack-
    I've done hydraulics on a few tractors by myself and lifting the top cover on and off by yourself is not easy. I won't do it again without help that's for sure. Having a helper is best done too when dropping the pump and reconnecting the linkages. Yeah, later parts catalogs will list the current p/n. You see many 9N/2N parts listed on ebay as being also for the 8N, but that just ain't true. Sellers either don't know, or think by listing all 3 will cover the bases when folks do a search. An 8N hydraulic top cover isn't going to work on a 9N/2N pump and system for instance. Why not get your nephew to help lift it and haul it? Like I said, it's going to be a lot easier to just replace the entire cover than trying to pull the arm off and replace it alone. replace cylinder and piston, clean pump, and get helpers to reinstall. That's what I would do. Your tact, do what you feel is right. I still would like to know how the arm broke as well. You're not under oath, so not required to answer, but I'm sure a few more out there are curious too.

  • Re: 2N Hydraulic Problem LOCATED
  • Did not intend sidestepping the HOW issue. Plain truth is I don't know! Had this happened on my 860 I would not have been surprised as it has been used and abused. However I've never felt the 2N had been. Hydraulics on the 2N have always been much stronger.

    I was using the sickle bar mower when the part broke. That certainly should not have put any strain on it. I suspect it was cracked earlier. Perhaps running a scoop in this clay soil of mine.

    My nephew is only 7 years younger than I but in worse physical shape. In my youth I could lift 200 pounds and walk away. Now the only way I can lift 80 is if it is two 5 gallon cans of gasoline.

  • Re: 2N Hydraulic Problem LOCATED
  • Maybe the previous owner of the 2N mucked it up. Perhaps he hit a large obstruction while mowing or plowing such as a rock or tree stump. It seems to me it would take a tremendous force to break that arm and that would do it. These N's can take a lot of punishment but like anything else, if abused hard enough, will have effects. As you said, the splined lift arms did not change, but removing one or both will present a challenge. Note there are two bushings in the 545 arm as well. JMOR may be right -the 8N 545 part may work, just delete the cam. Try calling Derek at JUST8Ns and ask him -he'd be able to tell you for sure.

  • The 8N part has the cam for the position control incorporated. The earlier versions have no need for that cam as they are draft mode only.

  • Re: 2N Hydraulic Problem LOCATED
  • So, if cam removed, will the part work? I'm curious I have worked on both 9N and 8N systems and never paid attention to that part.

  • Re: 2N Hydraulic Problem LOCATED
  • I fully expect that it will work even without removing the cam, as I see no interference point with the mechanism, but.........I have not tried it.

  • Copy/past from:

    http://www.yesterdaystractors.com/cgi-bin/store/model_parts.cgi?SearchArea=Ford&&md=2N&cat=Hydraulic%20System&r=mcats

    This Hydraulic Lift Ram Arm fit the 8N, 9N, 2N. This part will work for the 9N, 2N and early 8N but does not look like the original. This does look like the original for the Late 8N. For an early 9N, this part may require additional machining, such as grinding down the end raised portion, and/or shortening one end 1/4 inch and adjusting with shims. (Part No: 8N545B)

    Just8Ns sells the part "8N only" and no listing for 9N 2N. I've worked on the hydraulics on 8Ns and hundred series, but not 9N 2N so I don't know. I suspect it would work, but some grinding may be in order. They all use the same shaft so the splines will fit.

  • Re: 2N Hydraulic Problem LOCATED
  • I have one from an 8N The shafts are the same part number but it looks like the 8N Hydraulic Lift Ram may be different in some way that the pictures don't appear to show. Wonder if anyony knows if the 8N ram will work on a 9N/2N cover?
