Hello folks....I recently purchased an 8N from a guy that said it was a 1949. The serial number is: (star)9N36886(star). However, that number would trace to a 1940 9N. Everything on the tractor says it is an 8N (4 speed tranny, draft control, etc.) It has a front mount distributor. Assuming it is an 8n (discarding the "9N" stamp for a moment) the 36886 serial, could imply that it is an early 8N model (1947). Would it be reasonable to imply that Ford was using up pre-stamped 9N blocks on the early 8Ns? Thanks....d

The block could have been replaced,they bolt right up and both would have been front dist.Look for other clues,I know the freeze plugs where different on the blocks and some other slight changes that I can't
remember but someone on here will.

don't go by what's in that drain hole. all models came with petcocks, but many of the petcocks have been replaced with plugs over the years.
my guess is u really do have a 9N engine. i have never heard of 8N blocks stamped with a 9 instead of an 8. there were no blocks to be used up - if that had been the case, u would have a block with a 6 digit serial in the form of *9N2xxxxx*.

With the interchangeable engines in the N series, it's not unheard of for engines to be swapped.
My 8N has a 1944 2N engine in it as well.

Sounds like an engine swap. Does it have an 8n hood with ford
script? Does you doglegs have holes on the side bottom to bolt in?
Does it have a round shape disc on the steering box where the arms
bolt in or is it more oval. Lots of parts get switched out over the years
with these old ford tractors. Sometimes not a bad thing.

Nope. ALL standard 9N/2N Models used the "9N" prefix in the serial number. ALL standard 8N Models used the "8N" prefix in the serial number. Congratulations -you are the proud owner of a mutt. Nothing to be ashamed of or to be concerned with as many N's had engines swapped out over the years with 9N blocks in 8N blocks and vice versa. Model years and serial numbers mean little unless you are restoring an original early 9N or 8N, IMHO. What are important is if your tractor has a front mount distributor or and angle mount, if it's a 3-spd or 4-spd; if it has POSITION CONTROL; and if it is wired as an OEM 6V/POS GRN system or been switched out to 12V. As a newbie, the best investment you can make right now is to invest in the Essential Manuals and keep next to your Bible and read both religiously.

Yes sir....I agree....looks like it was an engine swap. All signs point to it being an original 8N with a 9N heart. I have another 1952 8N and pretty much everything matches except this guy has a front distrib vs a side distrib in the '52. The guy I bought it from doesn't have much history on it, as he bought it from his wife's widow friend (who didn't know much about it other than she thinks it was a 1949 model). Very clean little tractor that was barn kept and not ran for 2.5-3 years....but fortunately the gas was drained and the block is free. I'm tinkering with her now....step by step based on the great info on this site. Thanks again for all of the comments and assistance guys!
Thanks for the info sir!
Yes to the following: front mount distributor, it's a 4-spd; it has POSITION CONTROL; and it is wired as a 12V (next step is to verify if 12v conversion was completed....has a 12v battery and alt...I need to test coil if 6v or 12v and complete the wiring etc. and determine what electrical parts are missing/needed).

Yes, a 9N block would use the front mount distributor. Don't assume because you have a 12V battery and alternator it is wired correctly. The electrical will run on either positive or negative ground but a 12V switch over job requires some critical changes to be made. Is the square Voltage Regulator out of the circuit? Is the OEM Ballast Resistor in the circuit? Is there an alternator device that keeps the belt tight? Does the tractor run now?
