  • Hi everyone, First time post.. Are there any good informative videos out there on basic operation and maint of an 8N?
    I have 2 of them. One I use frequently and my other one is one my dad purchased new in 1950. It stays in my barn lol.
    Thanks in advance.

  • After trying a few youtube videos, most of them should be replaced with two still images. One of the pretty girl. One showing an exploded parts diagram. Ok, if you have lots of time to sit and watch videos, go for it.

    Unfortunately, for many years we have been trained to "toss the useless manual". Nobody wants to sift 50 pages of cautions/warnings for the occasional useful fact. The Operators Manuals for the N-Tractors are from a different era. There is useful information on every page. The Operators Manuals are even arranged in the order a new owner will most likely need the information. Basic stuff at the front, more in-depth service info in the back. For the most part, everything you need to know to own, operate, and properly maintain the N-Tractor, is easy to find in the Operators Manual. It would take many hours of useless video to come close to providing the same information. Beyond that, when more serious repairs and restorations are planned, the Ford Master Parts Catalog, and I&T Shop Manual are good to have.

    My electronic library of "manuals" includes several parts supplier catalogs. Many are available for download. The Dennis Carpenter Ford Tractor catalog is loaded with good information for restorers.

  • HiYa Mark-
    Yes here are several videos out there, You Tube has most, -try "Wrenching With Rachel" for starters. Many of us also recommend that you invest in the essential manuals for your 8N. There are originals and copies of the Operator's Manual, but you need to get the one that is specific for yours -front mount or side mount. Next is copy of the '39-'53 MPC (Master Parts Catalog); and a copy of the I&T F-04 Manual. Some are available here in MANUALS for free download. Some are available on DVD for a modest donation.

  • Tim, I am in the process of cleaning the parts that make up the hydraulic lift system. As I am looking reassembling the lift cover, pump and PTO, I was looking for some guidance and want to thank you for the document you provided in the How To section. I am making a spreadsheet to reference the torque values for all of the bolts. You said that 57 Ft-Lbs is used for the 7/16"-14 bolts to attach the lift cover. I believe that is also true for the PTO flange? I am looking for the bolt torque for the aluminum pump base to the bottom of the center housing. Is it the same? Also, how about the 7/16-20 bolts that attach the chambers to the aluminum pump base?
    I also saw on another site that the round covers that go over the inspection holes should only got to 45 Ft-Lbs
    If it would be easier, I could send the sheet to you to look over and possibly fill in other values? After I am done I would like to share this with everyone else.

  • HiYa Frank-
    First, thank you for referencing my article, glad it was of some help. I wish I would have added a bit more information like cam follower pin and control spring adjustment. Perhaps a Volume II is in order. Next, torque values are used on the fastener itself, NOT the device or part being fastened. The value is also based on the type of material or grade of steel the nut or bolt is composed of AND the thread size. We have a handy reference chart to download in our HOW-TO's, under GENERAL, or just click on the link below. If a fastener is required to be at a certain torque value, it will be listed in the manuals, mainly the repair/technical ones like the I&T F-04 and Ford Service Manuals. Some items are more important than others like cylinder head, bearing caps and rods, and the flywheel fasteners. You can find a chart listed in the back of the lime-green Ford 8N Service Manual along with all the other technical specifications. We offer that manual in DVD form on our SUPPORT page for a modest donation if you don't have one. Torque is often an overrated term by engineers. Add the fact that many folks do not know how to correctly use a torque wrench. Most decent torque wrenches have more than one scale and could be any one or combination of; Inch-Ounces; Inch-Pounds; Foot-Pounds; Meter-Kilograms≥; and Newton Meters. One must know what scale is to be used and how to calculate from one to another. For any fastener, common sense usually will win out. Never overtighten anything. No need to get crazy stupid with a 4-foot long galvanized fence post on a wrench to tighten. As far as that 45 FT-LB comment, I don't know where it came from as I briefly looked in my manuals and did not see it. 49 FT-LBs is around the spec for a 7/16-14 fastener, somewhere between a Grade 2 and a Grade 5 so I suppose that is what the person was conveying. The bolts that fasten the side inspection covers on are 7/16-14, probably Grade 5 or 8. The issue with the side covers is they are made of aluminum and when the paper gasket fails, oil will start to leak around the outside of the covers. Often fellas will reef down on the bolts with a wrench and breaker bar and this probably distorts the aluminum more and unevenly creating more of a leaking issue. My advice is if a torque value isn't critical and listed in the spec manual, go by the industry standard chart for fasteners, or better yet, just use plain old common sense and trust your own strength. Don't know your own strength? If real ambitious, you can make a practice gage with several different tapped holes and install bolts and studs and with nuts. Install the fasteners and set to their required torque values. Then using your own standard tools, wrench on them to get what mechanics call 'the feel'. I'd use both open end wrenches and socket wrenches. Also, try tightening a nut or bolt with your wrench, the n use your torque wrench to see how close you are. You could do the same on any fastener on the tractor and no need for an application gage, but just a thought. When you get your chart done, just send it to Tyler and he will post it on the HOW-TO's forum.

  • Re: maintinence
  • Thanks for the response Tim,

    I had fun with the follower pin replacement. I found a machine shop that replaced it for me in an hour after all my efforts to replace it without removing the follower arm failed. I have Zane's fixture and will perform the adjustment after I clean everything up. My sensitivity to torque specs comes from my job as a support engineer in water cooled electronic assemblies. They are very critical to component heat dissipation and water fittings. I see a lot of water fittings come back from customers that tighten them without observing the torque warning labels to the point that really expensive repairs are required. I probably seem overly cautious, but after years of leaky equipment from under torqueing my own equipment and breaking bolts and flanges, I wanted to put together a guide that I can use to avoid that. I am particularly concerned with the pump base. It seems like it made of pretty soft aluminum and I don't want to overstress the bottom flange or strip the threads where the chambers are fastened. The comment about the round cover plates at 45 FT-LB came from someone at another site who was concerned with the casting being thin. I like the 57 FT-LB for everything else with the 7/16-14 bolts. How about the 7/16-20 bolts used on the ram cylinder? I am thinking about 62 FT-LB. One other would be the 8N-638 safety valve.
    I am planning on getting some of the DVD's soon.
    Last, I wouldn't have even considered starting working on this tractor (50 8N 377551) without all of the advice, suggestions and even heated discussions I have read on this site. I have been playing with this for about 3 years on and off since I bought my "Baby" as my wife put it and am still learning thanks to everyone here.

  • We have a bunch of videos and books on our home page. Or you can cruise youtube and try to find some.
