Identifying an 8N

Thanks,
68 Mag

One of the recent posts sent me back to my notes from the rebuild of my '50 8N two years ago. Here's the casting dates information that I recorded then. The legend for the code is, as I understand it, like this:

Month=A (Jan), B (Feb), etc...through letter L. Day = one or two digit number. Year = one digit number.

But some of the codes are in the mm/dd/yy format.

So, in my case, the number on the head, A190, is Jan. 19, 1950.

Here's what I found:

Head A190 (between the #2 and #3 plug holes). Oil pan A250 (bottom). Hydraulic pump 2/7/50 (bottom) Tranny case B30 (right side, forward, low). Right axle housing 1-13-50. Rear end housing B30 (left side under PTO shaft, upside down). Engine B20, on starter bump out.

This is serial # 257591. The range is Jan 13 to Feb 7, a pretty tight grouping.

Hope this helps..... ..... .Ed

You realize that most engine s/n's are handstamped and faint to begin with..... .Dell
