I just bought a 8N, looking forward to tinkering around with it, I pick it up next week. Overall it runs good, starts right up, and is a tight machine, but it has a few problems, so I have a few questions. Haha! The first one is the brakes feel different from one another. The left has little free play while the right has more. If you put even pressure on both pedals the left will lock up before the right. Is this adjustable? Another problem is that it isn't charging the battery. Is there an easy way to tell if it's the generator or the regulator? The right hand lift pin is leaking, this seems to be common in the N series tractors. It is somewhat loose, similar to a loose bolt, if you grab it, it moves easily, not a lot but anybody would consider it loose. How bad can this be before a replacement trumpet would be needed? Thanks you for this forum. I've been browsing for a bit now and decided to join.

Before you tear it apart run it and see how everything works. No sense draining and refilling the fluids just to have to do it again.

It's mostly original, no cobbled wiring or repairs that I could see. Nothing welded back together. The wheel hubs are tight and the seals don't leak, all the front end bushings, bearing and ball joints are good, no loose play or wiggly wheels during the test drive. Gas tank is clean inside. The hood has the typical rot out in places along the ribbed lower profile. The proofmeter face is mostly illegable. 3400 hours and the tach needle moves with rpm, not really sure how accurate it is or if the hour meter works. Oil pressure gauge works, ammeter doesn't. It looks to have been cared for mechanically, not so much cosmetically, a good candidate for an easy clean and paint restore. I did some basic checking and testing before I bought it, though I didn't have time to dig into it. 6v positive ground. It isn't charging regardless of throttle speed, the battery is sitting at 6.1 v running and 6.2v when off. Looks to be a 3 wire generator, which I think it correct for the year. New battery- Interstate. The serial number is a 1951 and the engine and other casting dates are all around early to mid 1951. It has the side distributor. The governor area has a small leak at the block, which will be dealt wil later. The lift pin leak needs to be addressed immediately since the pin is loose and the fluid level is somewhat low. I certainly will not be firing the parts cannon at it. It runs fairly strong a couple of pops and farts when changing speeds but will idle with the throttle closed. Cold start with choke, warm restart without. Oil pressure was around 15 psi cold at idle, running around 10 or 12 when warm, somewhere around 30 when driving around and mid rpm range, if you go by the gauge. The transmission and rear end is quiet and all the gears work. I think repairing the pin leak, the charging issue and running it to see what it wants is the best course to take. I'll invest in the books, I usually do and have for my other toys and equipment. I'm going to pick it up on Monday or Tuesday. I've solicited a buddy who's into old iron as well to come along as I don't own a suitable trailer at the moment. Haha! I'm pretty excited to get it, I don't really need one, though. I have a 200'+ gravel driveway and parking area going to the back workshop. My plan is to use it to clear snow and grade the driveway. I probably will get into a front snow plow as an additional project for it. My old snowblower kind of works but shoots gravel everywhere, if I set it to not pick up the gravel it does a poor job clearing the front paved drive. A new track drive snowblower could be a good choice by what fun would that be? Around here it would be $4k plus for a used Honda. I could get to $4k (but I doubt it) invested in the Ford while spending time with the kid wrenching. A worthwhile investment. We've rebuilt/restored a '77 Kawasaki KZ650 for him and for me a '84 Kubota B5100 baby diesel tractor. I use it to cut the grass and mistakenly thought would be enough to plow snow with. Thank you for the replies, you guys are great!

Heck it wouldn't be a FORD if it didn't have bad leaking brakes... ; > ) 1st is to know if you have the early front mount distributor or the later side mount unit. Next is whether 6V or 12V is being used. It matters and both are wired differently. Mechanical issues are secondary problems. Tackle fuel/carb first if an issue, next is electrical and wiring. What does your AMMETER read when running at start-up/idle? Should be about 7 AMPS. Throttle up and should show a slight increase. A good reliable brand battery is required. Bargain house brands tend to be junk and can have poor lifespans. By stating GEN and VR we assume you have the OEM 6V/POS GRN electrical wiring. Verify with Pictograms. Don't assume. Don't just replace parts willy nilly until proven defective. Most of all, invest in the ESSENTIAL MANUALS and related documents. Your local GEN/ALT shop can bench test everything and tell you if GEN needs rebuilding. You can motor test yourself -get out your I&T F0-4 Manual. Ya gotsta know certain things B4 doing any work.

I will add the axle trumpet comes off as an assy you do not need to tear it down. A engine crane are such will make short work of it.

I don't remember if Bruce mentioned all you need to pull is the left side once off reach in remover the center section (pumpkin as some call it) then you can get to the other pin. I use to be able to man handle that I am not sure anymore.
Brakes, if they lock up adjust and move on with life, life will be good.
BTW those axle housings should be available as they don't sell well.

Hey Bruce, thanks so much for the detailed reply! I hope the trumpet isn't wallowed out and the repair goes as smoothly as your description. I have experience with automotive rebuilding work and plenty of tools to enable this repair. I suppose the brake work will reveal itself when I take it apart. Both side axle seals are dry so at least it isn't a leaky seal causing the brake difference. Now to order some fluids and gaskets! Jim, I'm going to look up some YouTube videos regarding servicing the N series. I didn't think of Youtube, thanks for the idea. What an awesome forum!

Yes, the brakes can be adjusted, but the problem you are having is most likely hydraulic fluid on one side and not the other.

To stop the leaky pin, you need to replace the pin. To do that, you need to remove the axle trumpet. If you remove the left trumpet, you can do them both at the same time. It's held on by a castelated nut w/ a cotter key on the inside.

Drain the fluid (see tips 3 & 4, below. Resist the temptation to park it nose-down in a ditch or to jack up the rear end. If you have a bad front transmission seal, you will fill the bell housing with hydro fluid. Then you get to replace the clutch)

Remove the left trumpet & slide the differential gear out. (an engine hoist is a good idea) Make sure the holes are not wallowed out or you will be in there again. I hear Loctite Quick Metal 660 Retaining Compound, Press Fit Repair.works.Or if the axle housing is really worn, you can use Loctite Fixmaster Fast Set Steel Epoxy, but I've never had the problem so I can't say for sure. Referring to the picture, the pin you need to replace is p/n 563. The hole which may be wallowed out is in the trumpet, p/n 4010 or 4011. The nut that holds the pin on (which is inside the differential housing) is p/n 33860-S. The cotter key is p/n 72035-S. Torque the nut on the new pin to 150 lbs before you put the cotter key in. Wipe the new trumpet gaskets w/ warm water until they are sufficiently pliable to stretch over the studs w/o breaking. Let them set a few minutes before you put them on. Make sure you use your favorite gasket sealer. Torque the 11 trumpet studs to 40 lbs.

And, beware of mission creep: the rear end is probably full of 50+ years of crude, so have some kerosene & rags ready to clean it out .

Sorry, can't get my flow chart for checking the charging system to post.

I have a video cassette I bought in the nineties from a man in Pine, Colorado that covered repair of the brakes, axle,seals, and hubs. It also covered removal of the left trumpet and the differential, PTO repair and other maintenance. His 8N was named Harriett. The tape is about 2 1/2 hrs. long. There should be YouTube videos available with the same information.

In the 1960's I used to haul those missirable things into the ford repair shop for brake work. The old boy told me Manny times Henry Ford designed the brakes on these to be a little better
