Dr Allis: Can a D19 rear be matched up to a D17 without much re-engineering to make a "D18" Have a Pic of D18 with 18.4-34's on bar axles (D19 Rear end). Thanks, Elvin.

Piece of cake. Everything bolts right up. Years ago, I wanted to drop a 433/F2 engine in a D-19 chassis and use D-17 hood and fuel tank. Build a live engine powered hydraulic pump with a 170-185 hyd valve stack to the right of the seat.

That would make a cool tractor!

Notice the D19 behind it...?

 "Years ago, I wanted to drop a 433/F2 engine in a D-19 chassis"
Doc, I wanted to do that too, but those 433 engines are kinda hard to find up this way. Had thought about a 4BT Cummins engine swap... Or a 4.236T Perkins. Sadly, stuff like that takes time to do.

The D18 in the picture is a factory experimental tractor that was shipped to North Carolina by mistake back in the day. It was supposed to be shipped back but it never happened. Picture was taken at the Pontiac Ill show in 2018. I'm personal friends with the owner who has the full history of this tractor.

Dr. Allis. Have a friend who replaced the gas engine in a OneEighty with a 433/F2 engine. He loves it.

An F-2/433 engine into a One-Eighty would be easy, once you transferred over the front cover so you had a hydraulic pump drive, or maybe he went with a front pump drive like a late 170/175?? There'd be room for that.  Getting the fan to the radiator or getting the radiator shroud to the fan would be a challenge.    Calvin, I wonder if that ex D-19 chassis had a serial number?? located right behind the seat stamped on the top of the housing.

What would you gain from building a D18 vs a D-19? Honest question, not bein snarky at all just curious.

I'm not buying the story on the D18 pictured as being the real deal. There's several things that are not correct. The big one is the front axle. The D18 prototypes have the D19 heavier front axle. The one pictured has a D17 front axle.

Allis built a prototype d18 during the development that would eventually lead to the production of the d19. Building one would be a neat endeavor for an allis enthusiast who has the time and resources and would be a good conversation piece at shows. Kinda like the red guys that build Farmall HTAs.

The production D-19 was released in December of 1961. It indeed had
 the more modern looking and rugged wishbone on the front axle.  I'd like to think the D-18 proto tractor(s ?) would have been field testing in late 59? and surely thru 1960 ??   and maybe the actual D-19 proto's were only tested thru the 1961 year time frame ?    Well, I have a piece of Series 2 D-17 advertising literature. The printing date was Oct of 1960. It has cream wheel centers. Persian orange #2 is the color and a horizontal mesh screen grille, painted cream. Hood has the riveted on Allis-Chalmers emblem plates. It clearly has the old style wishbone front axle. According to AGCO parts books it appears that old axle design stayed on the D-17 until the series 3 models in 1962.  I guess what I'm trying to say is, the D-18 probably did have an early design D-17 front axle under it. Swinford's book makes reference to the D-18 with the short D-17 hood and raised up fenders didn't look rugged enough. The front axle wouldn't have looked rugged enough either, so the real D-19 got a change. I'd sure like to see the S/n on the rear end of the D-18.
