9N-2N ID

Message:

My buddy has a '47 2N. I was showing
him how it was the same as a 9N , even
the engine serial number started with 9N.
But then he pointed to the raised casting
number on the axle trumpet which along
with the raised '47 casting date it has
a p/n starting with 2N. Was that part
changed or improved over the original 9
part ?

If a part was added or redesigned between model years, it would carry a new prefix to designate when first used. Yes, all 9Ns and 2Ns had a 9N serial number prefix but parts changed over the years and those would show a new prefix. If a part was just modified, it often would show a letter suffix to define the new part and it would supersede the old part. One example is the early 9N-10000-A generator. It soon was necessary to improve the output/charging rate and thus the 9N-10000-B generator was released. Parts would carry over to each model year if no changes were made to it. You will find the 8N with 9N and 2N prefixed part numbers.

as others said.

remember.. the 9n/2n axle trumpet had changes at the fender bolt holes.

There are a number of parts on the 2N that are not the exact same as the 9N. The radius rods for one. From what I understand the changes where made so that they could keep making them during WW-2
