Differences in each 800 model

Can someone please point me to a manual, scroll, leaflet, magazine, pamphlet, book, library full of books, anything that can tell me the differences in the 800 models. Google Images are getting tired of me asking them to keep pulling up photos for comparisons.

Also, are there manuals available for each 800 model or maybe just the 800's?

Thanking you so much in advance.

PS - I managed to replace all the freeze plugs the right way.
 

I&T manual number FO-20. Yes, this site sells it.

Yes it is the manual for the 800 series Ford and this site has them. There are a number of models of th 800 series like the 840 which has 4 forward gears. Then there is the 850 and 860 bot have 5 forward gears. But the 850 has the nonlive PTO and the 860 has live PTO

Hey young fella, since Mark, in his original post, asked for a reference to tell him what are the differences between the different 800 models it appears to me that he knows that there are different ones.
 
(quoted from post at 18:47:09 03/23/21) Chart showing all models and the year each model was produced.

From the chart maybe an 840 or 841. Still don't know the year though. I've started to get measurements on most of the parts needed so I can order them that way. I do know I have a 3.90 bore and rod bearings have 0.40 stamped on them. But I have to know what the original journal measurement is in order to know if I'm over the limits.
I have a 10" clutch that needs the disk replaced. I need to replace the pilot bearing but I guess I'll have to remove it and measure it as well. Throwout bearing and hub as well.
The head looks good along with the valves. I did lap them though. I'll hone the cylinders today.
I'm going to need manifolds which I assume will be expensive. Is there an aftermarket on them?
Wire harness as well for 12V conversion.
All gauges including proofmeter.
All tires
There are O rings on the bell housing for the hydraulics that meet up with the manifold on the engine block. Need those too.
New fuel system minus the tank.
New seat.
On and on and on and on.

I do have a Ford tractor manual and it gives specs but if you don't know your model number it's useless.
 


Well then, now it is apparent that you started out asking the wrong question, LOL. The difference between the 800 and 801 is little more than the paint and year. 98% of the parts are the same between the two. The model and serial number are stamped into the bell housing. If you stand with your left hand on the starter and right on the clutch pedal and look down you will see either 840 or 841 stamped into the horizontal flat surface. You can get most of the parts that you need right here at YT. In the interest of everything coming together successfully for you I suggest that you consider following the common practice of taking your block with cam shaft and crank to your local machine shop for cleaning, evaluation and prep for reassembly. They will take measurements to see if just honing is adequate or if boring is advisable. The bores are often tapered beyond spec. They will evaluate your crank to see if it needs only a polish or a grind. If it needs a grind they will tell you what size bearings to use. They can resize your rods. They can evaluate your camshaft and install the new bearings. If you want the insurance, and probably save some money you can order the bearings and rings and pistons if needed from the machine shop so that you know that they are all going to go together. Don't bother measuring your pilot bearing, clutch release bearing, or hub. Enjoy yourself and don't hesitate to post back.

I appreciate the info. So far I know that the difference between an 800 and 801 are the paint and year. How about the other 800 series models? From the chart posted above, I am guessing I have an 840 or 841 but all of the identifying marks, such as the area you pointed out are no longer present. They are gone. Wiped clean - no more. LOL That's the issue I'm having in the identification.

Taking the block to a machine shop sounds expensive. Since this is my first rodeo with a Ford, I'm just going to tackle it myself. It's only going to be driven around the yard so it should be fine.
 
An 800 will have the left side brake pedal shaft crossing in front of the rear housing to the left side of the tractor as shown below.

An 801 will have the left side brake pedal shaft crossing under the rear housing to get to the left side of the tractor as shown below. My project 841 has the rear mounting bolt for the running board broken so it makes a good demonstrator to show the 801 left brake shaft routing.

Uh oh. What if I only have brake pedals on the right side? And I'm new at submitting photos. I hope after I push select it works right. LOL.

It is isn't it. But I think I'm going to take the crank to a machine shop and have it turned to make all the journals the same. The engine blew a head gasket between #2 & 4 but it's not those journals that are worn. It's the outer ones that are 0.008 worn more than the inner two.

Uh oh. What if I only have brake pedals on the right side?

All 800 and 801 series Ford tractors have both brake pedals on the right, but the brake pedal closest to the side of the tractor is for the left rear wheel. The actuation rod is different between the 800 and 801 series where it crosses under the tractor. Reread my response and study the pictures I posted to see the difference.

Ok, I'm a little embarrassed now. It looks like the brake pedal shaft is passing in front of the rear housing so I would assume this is an 800 series? If that's correct, which model in the 800 series do you believe this is? Thanks. Mark

Mark, I agree with Michford ....REREAD...........REREAD.......or maybe read for the first time? I can see from the gray paint at the bottom of the dogleg that your Ford must be an 800. I can't understand your obsession with exactly what model it is. It is highly unlikely that it will make a shred of difference!! I have had these old Fords for 22 years, and I know that it rarely makes a difference. Almost every place that sells farm equipment has a rack of IT manuals on sale. Have you tried to get one?? Since you can now post pictures, If you post one that is in good focus of the place where I told you to I will see if I can read the numbers for you. In my 20 years on YT there have been over 15,000 guys that have bought old Fords and have bought many parts for them without concern for which sub model it is. As I pointed out before, 98% of the parts are the same between an 800 and an 801. Pistons, rings grill, manifolds and carb are different.

The left side view shows the clutch pedal in front of the split,,the view of the right side shows the brake pedals are not 800 series. I know nothing really, just observing the pictures and comments.

First, I have no "obsession" to find which model I have. Am I curious -you bet. This is the first tractor I've owned, let alone torn down so ease up a bit. Maybe a better response would have been, "Hey Mark, the model doesn't matter. Just order your parts for a 172."
I have one manual at the house and the FO-20 is in the mail.
And I'm sure your numbers are off a bit - I bet it was more like 15,001 guys who ordered parts without telling the parts guy what they had. "Nope - you don't need the model number. I own a Ford tractor and I need a bearing so gimme me whatcha got." I'm sure it didn't go down that way.
And the dogleg eh? I was a firefighter/paramedic for 30 years and I would never describe something to anyone using technical language if I wasn't sure of their level of expertise. "Hey Bob, I started a subclavian artery IV last night on a patient with a tension pneumothorax, pushed 40mg of Dexamethadone and I used a 14 ga." Far out, you know I'm a plumber...right? Oh. Geez.

Mark, The point is that all of those guys can look up the part numbers without needing to know the sub model. I am at a loss about the dog leg term. It is hardly technical. Call it whatever you want it doesn't change the shade of gray.
