  • Made the swap for a 50 8N
  • 7 hour round trip to trade my '44 Farmall B for this 1959 8N. Unfortunately the pictures from the ad made it look better than the tractor is up close and personal. But I made the trip so went ahead and brought it home. The guy put a new carb and coil on the tractor, but I think it will need some adjusting on both. Hard to start and seems to be running rough.

    Oh, well - it's home now and in the garage.

  • I deciphered the serial number on the engine block enough to believe the engine is from a late 2N. That serial number starts with *9N299.... But further investigation reveals this:

    I found a casting date of "G67" on the transmission tunnel housing, meaning a date of June 6, 1947. I found what I believe is the serial number on the left side of the transmission housing just forward of the PTO lever, of *8N402*, meaning it's an early 1947 8N. Only 401 were built in 1947 before this one. I'm sure with everything else I'm seeing this is indeed a 1947 8N.

  • The number that you found on the side of the transmission housing is not the serial number. Ford N series tractors only have the serial number in one place and that is stamped into the engine block.

  • Right now it's the closest I can come to identifying the year of this 8N. The stamping on the transmission and the stamping on the transmission tube, and with the other features I'm seeing, makes it an early '47. The serial number on the engine is stamped *9N2?93..*, which is all I can legibly read. So the engine has been replaced at one point.

  • I meant July 6, 1947 as "G" stands for July.

  • Re: Made the swap for a 50 8N
  • As I look over this 8N and compare it to the research I've done, it seems to be more of a mystery. The serial number on the engine block is too hard to read - almost impossible. It has the side distributor, but the oil filler tube is in a location that it would be on a front mount distributor engine, as Ford move the oil filler tube so that the generator can be mounted on the left side. This tractor has been converted over to 12V, so they were able to mount the alternator away from the filler tube.

    The steering box is from an early 8N, and the clutch linkage is from an early '47 8N. It's possible the engine got replaced by a side distributor one, but the oil filler tube defies that it was a side distributor engine. Was there an aftermarket kit to convert a front mount to a side mount distributor?

  • There were three different filler tubes used. Sounds like you have the long one used on early engines. See if you can find one of the shorter ones. It will fit the hole fine and probably fix most of your problem.

  • I don't know if a smaller tube will fit between the block and alternator. Here is a couple of images of the tube. Note the way they braced the lower part of the alternator in the second image.

  • Re: Made the swap for a 50 8N
  • Yep, That's definitely a front mount block converted to a side mount!

  • No after market kit needed, just later 8N standard parts, timing cover, camshaft, distributor. Note the two raised casting bosses with generator mounting bracket studs....these were not on earlier blocks that had generator on right side of engine.

  • Re: Made the swap for a 50 8N
  • Thanks, I have to recheck that.

    It has the spark plug wire rail, but it's been flipped backwards so they used it to wire tie wires, etc. The oil filler tube has been bent back against the block to allow the alternator to be mounted. It will be a pain to fill the crankcase since it's almost touching the underside of the fuel tank. I can get the cap off, but it will require a flexible hose to add oil. The timing cover has been changed to allow the mounting for the side distributor. The coil is mounted behind the dash, above the battery. It's amazing what previous owners will do over the course of their ownership. I kind of wish they would have left the front mount distributor on it, left it 6V, etc.

  • I believe it's a 1950, since it does have the side distributor, but not the proof meter, which also came out later in 1950. One guy on FB said he had a 48 and half that had the side distributor. I didn't bother to correct him, as I'm sure the side distributor came out in 1950.
