1948 8N - Industrial Engine?

[calicopatchfarm]

Recently, my mechanic was over to work on my 1948 8N (see pictures 1 & 2). He noticed a plate (see picture 3) on the engine block. He wondered if it was an industrial replacment engine/block since that would be the location where a fuel pump would be attached. On the other side of the block, the serial number is 8N88187. Which would put the tractor around mid 1948. Additonally, on the axle, the date is stamped 5-18-48, which would make sense. So the block would seem to be original. We compared it to our "51 and it was just a machined surface (see picture 4). Any information/explaination would be helpful.

Patchy......congratulations, you have the "braggin' rights" to an ex-fuelie 1948 8N-Engine; s/n 8N88187.

Dunno, about the "fuel-pump" boss being plated. Ford sold their N-Engine for many applications that used fuelpumps, like WW2 Jeeps, railroad car refrigeration; Pullman car air-conditioning, irrigation pumps, oilwell pumps, 'lectric lite plants, grain combine mowers. Heck, they were even 60hp giants in 1/4-midget racing. Parts are the same.......HTH, Dell

These engines have been through so many permutations over the years. Could have been the original engine. Could have been an engine removed from a tractor, sent to a machine shop for reuild as a combine or baler engine then rebuilt again and put back in to a tractor. And the date codes match...
Someone here must have closeup pictures of a true industrial that you could compare the machining on the fuel pump land to see if yours is OEM.
I asked the question the other day if all Ns had the excentric on the cam to run a fuel pump but nobody answered.

Dell,

I think I followed what you were saying. But I am still alittle confused. With the 8N serial number on the block do you think it was the original engine in the tractor?
Thanks

Patchy......with axle date marks of 1948, probably original engine, but who knows??? Does it really matter, they all fit. Plus you gottz some unique "braggin' rights" ......Dell
