ford 8n pistons

The number on my pistons starts with 9n does this mean its a
9n piston or just a part number. Its a 51 or 52 8n
 
8Ns shared Many parts with 9Ns and 2Ns.
If the part was originally designed and installed on a 9N it would retain a 9N part number for as long as it was used in production or untill it was superceded by a later part.
Here is an example.
2N upper and lower spindle bushings were part # 2N3109 (1.250" I.D., 1.370" O.D., 1.500" long)
That same exact bushing/part # was used on all 8Ns and for the Upper spindle bushing on all of the Jubilees, Hundred Series and smaller Thousand Series (2000, 3000, 4000)Ford tractors.
 
(quoted from post at 22:17:37 06/19/14) Thanks i have the pistons was just curious if there was an engine swap
I was trying to point out that there were more than one type.
3 ring vs 4 ring, etc.
An engine swap would be obvious between a 9N and a '51/2 8N.
A late 8N engine would have a side mount distributor and the
generator on the left side of the tractor when in the seat.
9N would have a front mount distributor, genny on the right.
No mounting bosses for the generators on the opposite sides.
That's not to say the pistons couldn't have been swapped tho.
Lots of history with a 60+ year old tractor!
