8n serial #

Just got an 8n with side mount distributor. The serial number flat plate on left side of head has no number on it. Possibly ground off although surface is smooth, not scarred. Behind this plate stamped into the cast of the head is the number I287. What does this say about this engine or the tractor? Does this mean the engine was re-manufactured and they removed the serial number?

SN should be on the block just above the starter, not the head.

Check out the Ford N site right here on YT.

Serial number is on the block, just below the head, almost behind the aft end of the oil filter.
If you've found that flat and it is completely bare, it's probably a replacement block that was never stamped.
They were just lightly stamped with hand tools though, so they are sometimes hard to read and full of paint.
They were not raised/cast numbers/letters. Hand stamped in.
Ford used the "I" to represent a "1".

Casting code on your head indicates Sept 28,1947. Check the engine casting date code just behind the starter.

Side mount distributor would be 1950 up And I am thinking the head is different to mount generator on left side soa head for an earlier would not work on the later tractors.
 
Kirk Looks like the casting number is 1051, but first digit real vague. And I screwed up when I said the flat ID plate was on the head... it is just below. But that was good info that pre-50 head would not fit side mount block.
 
"pre-50 head would not fit side mount block"

The main difference I know of in the head, is that the mounting for
the oil filter was moved back a little to clear the generator. Anyone
else know a reason the later head would not work on an early block?
 
"I thought the generator mounted on the head."

No sir, the generator mounts to a bracket bolted to the block.
The blocks are definitely different because there was no provision
to mount the generator on the left side of the earlier blocks.
I should have taken pictures of the generator on my '52 while I
had it out today.
 
just as added info; I have a 9n/2N whose engine serial number places its production in 1943, IIRC. Generator is small, 3-brush, on right side of engine. Simple enough and typical for 9N and 2N units. However, on the left side I have a little confusion. The oil filler/breather is right where a left-side generator would need to mount, so that is a feature of 9N/2N block. HOWEVER, the oil filter mounts to the head, and it sits back far enough that a generator could fit on the left side. Also, the oil filter bracket partially blocks the view of the serial number stamping on block. REASON for all this? The head has another name, not Ford. This aftermarket head was made for a later tractor, 8N, which could have the left-side generator. SO, THE HEAD FITS THE BLOCK, BUT IS REALLY NOT CORRECT for this tractor. Will I change the head? Heck no. That's my story and I'm sticking to it!
