Is there a listing of the location of the serial numbers on AC tractors? Thanks.

Not that I recall at the moment.

B, C, CA, is at the base of the gearshift lever.

WD/WD45 is above the left rear brake spring hole

"D" Series up to D17 is on the rear left side of the engine on the bell housing

D19 is on the back center edge behind the seat mount. It might be covered up with oil & dirt or a hydraulic line, or both.

Hope this helps you for starters.

Here is a link to Bryan Smiths Webpage.

Lots of technical info. for Allis Chalmers.

For a list of Serial No. Locations, find it in the R/H column.

The Steiner catalog has locations as well as serial number breakdowns. This page also has year charts under the home page - serial numbers.
