Story of my ford 9n 8n hybrid (long read)

as I said the other day I would post my 9n's story so here it is:
The story of my 39 9N with 8N engine. So it starts the day I went with my mom and stepdad (i’m 15) to their buddies place, we were chatting around when the buddy (i’ll call him Bert) asked me “what's the oldest tractor you drove?” I said the oldest I drove was a 1945 WC that my great grandpa owns. He said well this ones a 52 and points at what I assumed was an 8N. It had custom hood sides that didn't fit right, a custom bumper bolted to the hood side brackets on the radiator and it was all white with a red engine and a 12 volt conversion as well as a broken three point hitch that wouldn't lift. He asked if I wanted to drive it, I said sure I wanna drive it. The battery was old and not working so he had to jump it but it fired right up. So i went for a drive around, I tried to give the old tractor a little throttle, 3 notches into throttle *boom, loud backfire. No good I said, it wont run good. Eventually I had to park it and we went home shortly after. A few weeks go by and we go to Berts house in town now. He says he's selling that tractor for 1200$ to anybody but because he saw I liked the tractor and that i'm younger i could buy it for 500$. I jumped at the opportunity and arranged the purchase. One month later we headed out there to get it. We got there and it's already running but almost out of fuel, we brought gas for it and fueled it up. That's when he said “that's the first tank of gas it had in the 2 years I've owned it”. Yikes I said to myself, no wonder it wouldn't run nice. So we then set off 20 km to home from his place in -16c weather. It was cold but we eventually made it. The next day was the first things we did. We changed the battery as none of our chargers would start it and we changed the plugs to ensure that it would run well. That was the day I looked around the tractor and figured out it was a 9n. When we finished changing stuff I pulled the harrows to flatten the driveway and tried revving it up, this time it sounded rough and tried to stall above half throttle (it still does that). So i said eh i'll just run it below half. Then after we brought it out to my nan and papa's place to get it fixed up right. During the months of November to January we did a lot. We changed the hydraulic pump and found out it wouldn't work because water had gotten in it and froze, literally exploding the valve chambers of the pump. So we got a new one. I wanted to see if it was a 1939 so i put a magnet to the trans cover and dash and it didn't stick meaning its cast aluminium which means its a 1939. We also replaced the steel mesh grill and custom hood sides with the proper hood sides and a later grill (I'm not paying 1500$ for a 1939 grill). We then replaced three really worn out tires, two front and one back. Then we tested the hydraulics after everything was all back together and they still wouldn’t work. We then brought it home despite the hydraulics not working and I used it for pulling harrows with the drawbar. Then one day I said well I'm going to take my brother and my cousin sledding behind the tractor in gear three, it broke trails through the snow really well and for that reason I named my ford 9n Buster. We had a ton of fun and it turns out the Ford 9N can drift on ice like a sports car can on the road. So we did that for a while until the carb had a float issue and needed to be adjusted, so we fixed that up and continued on our way. Then one day out of the blue it hit me why the hydraulics wouldn’t work, we didn’t put the control valve in far enough. So i drained the hydraulic fluid down to the bottom bolt and took a flathead screwdriver and pushed it in more, i started it up and engaged the pto and it lifted but wouldn't stop so i shut it down and pried the valve out just a little bit and now it lifts and lowers. Now my next plans are to change the resonator on my exhaust out for a proper muffler and to give the tractor a new paint color. The new paint color I do need ideas but as it sits right now i want to paint it pink on the bottom, ford beige on the hood and fenders and the rims are white outer and red hubs and inner. But I am open to suggestions. (here are the before and after pictures so far)

Nice write-up. It sounds like there are plenty of old 9N parts available in your area. When you feel like attacking the back fire and reluctance to get past half throttle, pull the distributor and check the centrifugal advance. I'll bet it's frozen up.
 
Welcome Kondoge,
Thats great you got it home and started fixing it up.
A 52 8n engine would have the gen, or alternator on the port side, so your 8n front mount is 1948- early 50.
Be careful on your N. Guys have been killed when it tipped over on them.
Years ago, on a hillside, I tipped a small Kubota onto its side. Was able to jump off uphill. Friend and I were able to lift it back upright.....
 
Aluminum dash/trans cover was used into 1941 so it’s probably not a ‘39. Is the starter button on the dash or by the bottom of the shifter? Where is the key located? Show some pictures from all sides.
 
Here’s more pictures that I went out today and took. Also note the steering wheel was changed and so were a lot of other things by one of its past owners that had no clue what tractor it was or what they were doing. Also the engine was swapped

It’s a 1940 9n. Serial number would have been between 12500 and 15000. The trans cover dipstick is wrong so don’t know if the hight is correct. There is a trans plug on right side of trans to check overfill but they’ve been there without taken off they get rusted in place and I’ve heard of guys snapping them off and cracking the case.I would remove bottom bolt on round side cover for overflow. Will check later today on dipstick hitch. Good luck with you new tractor
 
thanks for helping me correctly identify the old 9n. what did you mean by the trans cover dipstick is wrong? and that plug I really don't want to take out as it seems to be working fine. and would that 90 degree bend in my pipe hurt anything? I just have the feeling that I should change it to a curve. I also have the original hydraulic pump if ya'll wanna see what water can do when it freezes in there. and for the numbers of it

Don’t have a ‘39/‘40 dipstick hight. Maybe at the other farm. Won’t be there until the spring
 
Be advised. plastic inline fuel filters make some folks persnickety. Both of my tractors have one.
I use a metal inline filter. I was wondering if this restricted my fuel flow so I disconnected the fuel line at the carburetor and timed how long it took to fill a cup. It took 8 seconds so 1 pint would have taken 16 seconds.
 
Hey I’m actually out working on the tractor right now I tried to start er up and the starter wouldn’t stop and it did eventually stop but now it has no engagement power at all what did I do now
 
Switch probably stuck or starter button.When this happens disconnect the battery or maybe smack it with a hammer. Hopefully you didn’t burn out the starter

yeah I did hit it with a 5lbs hammer gently and it worked again. also we didn't do my wiring wrong did we. funny thing, turns out that top link really hurts to get your fingers caught under when it falls
 
Found a ‘39 trans with dipstick in it in the barn. Dipstick is 12 1/2” long from where it rests on top of trans cover. From the bottom up 9/16” to low line. From bottom up 1 1/8” to full line

I think mines a little long I’ll send a picture of it next time I go out but that won’t be for a while it’s -30 till Wednesday plus I just fill it till it leaks out the bottom bolt of the inspection covers and no more cause it leaks into my right brake drum if I put more in
 
Here’s the old hydraulic pump I took pictures of the the broken pistons and valve chamber and the numbers for y’all, if you want me too I can take him apart and show you guys all the pieces that I put together to make it look like it’s together. please don’t be like busters previous owners, if you see water contamination change the oil because this happens if you don’t

The only problem I have had with inline gas filters is the ones that have the 2 step, 1/4 and 3/8. I have no problem with the 3/8 just squish the rubber hose with a clamp.
 
Yeah but ima try to get a sediment bowl and the proper fuel line, also That’s on the diff that had JB weld covering a massive hole. It’s working so don’t matter to me
