I have asked a number of old time AC folks why or what the WD letters stood for?

Bryan is headed the right direction, the W is the engine type. The C, D and F designations are the tractor. The WC which came to life in 1933 with waukesha engines were converted to AC W201 engines for production in 1935. After the row crop version became popular the WF with the standard tread was introduced. The WD was an upgrade of the WC with hydraulics, the handclutch which gave live PTO and the traction boost system. There was a prototype of the 45 called an F also but it later became the WD45, most likely as Bryan stated because it was near 45 HP.
Most of this information is from Norm Swinford's book, "Allis-Chalmers Farm Equipment 1914-1985" which is highly recommended for the history of AC.

Well, the WD-45 was an upgrade from the original WD, hence the addition of the 45 (probably for 45 hp or thereabouts, since the WD45 was 43 belt hp).

The WD was an upgrade from the WC, hence WD instead of WC.

WC could have meant nothing, but as I remember it may have been called "all-crop" for a while. The WF was a "standard," non-adjustable wide front end version of a WC. I'd guess the "c" portion had something to do with cultivation or crop, but no bets on that. No idea what "w" stood for.

All these are my guesses. WC could have been a generic, off-the-wall designation with no associated words or could have been the next in line of a particular model designation class. Norm Swinford's book - and CH Wendell's - may shed some more light on this.

I wonder if the W was for the W engine? Where that came form though is another question.
