wc allis transmission

does anyone know where the transmission on the allis styled WC originated from. It looks to be some kind of pickup transmission originally.
 
I have a 1939 WC and never paid much attention to the make or model of the trans . But your right about using truck trans in equipment . We had a 230 timberjack and it had the same trans as a 2 ton dodge of ford . SO the WC could be a Spicer , Borgwarner etc.

The safety lock for reverse is similar to an old truck I used to haul grain with. Some of the tractor companies used vendor supplied components like engines transmissions and even rear ends
 
Lots of local farmers had "35 to '42 Ford 1 1/2 ton grain trucks with the same shift pattern and reverse trigger when I was growing up. Often wondered who made them and never found out, probably Borg Warner, but still don't know.
 
Might be that it was BASED on an existing 4-speed transmission, but I suspect it was built in-house, because they used the same gears in the WD for a few years and the housing for that one was built by Allis.
 
I would say Clark.....here is a 1957 ad for Clark and I can identify both the WD and CA housings.
As stated most of the gears in a WC are the same as the WD.

Wow! I have to agree that ad is dead on. I think that Clark
also supplied the Allis B and C also. I would also bet they
supplied them for the Oliver super 44 & 440, IHC B and A,
Cletrac General and HG and a bunch of others. If you look at
them, they all look alike.
 
Yes you are on to something with these other transmissions. However with the WC it is different at least the housing. since this thread started I have found out that the WC is definitely the same transmission used in the 40s model Chevrolet 3/4-2 ton pickup trucks.
 
Assuming it is the same, it would likely be a Clark tranny, I guess.

dont forget the WC & maybe other models had a differant rear end housings during the war years , welded together not cast , i do know allis was known for using truck & other equipment trans, and such for there tractors , they put it up for bid to other companys , why ? dont know , easier , cheaper
 
Yes you are right it was Ford trucks. It was an old Ford that I drove for awhile with the similar transmission not the 40's Chevy trucks. Any way it was very muck like the Allis WC I now have.

Allis Chalmers sold components to smaller companies such as Clark for use in their own equipment. If there is a resemblance to WC parts, it's most likely due to a manufacturing agreement of some kind between the two companies where either A-C supplied the units, Clark had a licensing agreement with A-C to manufacture them, Or possible the A-C patents had expired. Another interesting point, the WD was last manufactured in 1954 and the Clark ad is dated 1957.

At the time the WC was built A-C was a huge manufacturer company with foundries quite capable of building anything they needed. Allis Chalmers tractors used only in house foundry components.
 
I would go so far as to speculate this: Allis-Chalmers cast and machined their own housings and bought the transmission components from Clark. I believe they did this up to the point when they came out with the constant mesh/helical gear design with the curved gearshift. This would have started sometime in late 1952 or surely early 1953 in the last of the model WD tractors and carried on into the WD-45's. The rearend casting changed slightly to accommodate tapered roller gearings on the bottom shaft, but all the transmission gears, shafts and ring & pinion were different. I think A-C made their own gears from then on..... Like I say, only speculation on my part.
 
Well MD, we can speculate all we want, but....do you disagree that that is a WD housing....and....a CA housing as well?
I would "speculate" that Clark may have continued to use the picture of the WD housing that they already had on file rather than go to the expense of taking a new photo of something that, except for the shift lever, is essentially the same housing.
My handwritten note on the ad indicated that it was a WD housing!
The ad speaks of "designing for a need"......maybe Clark designed and Allis manufactured?

Brian...Sorry you seem to be upset by a differing opinion. Your speculation is just that, you have formed a theory about this subject without firm evidence. Pictures in a company ad does little in providing proof especially in regards to the WC transmission which is the original genesis for this thread.

Prior to the introduction of the Model WC in 1933, A-C had already acquired such companies as Monarch Tractor Co., Stearns Engine Co., Advance-Rumely Thresher Co., And Hi-Way Machinery Company. Given the fact that these companies had already been producing such products as tractors and threshers, providing those ample resources for the manufacturing of transmissions and their related components in my opinion would be self evident.

Further more, given the time period the WC was manufactured, companies did little if any "outsourcing" as large companies wanted to “own, manage, and directly control” every aspect of their products. The concept of "outsourcing" didn't begin until the 1950's were profits outweighed full control and the term wasn't formally identified to as such until the late 1980's.

With all this imperial data and no conclusive proof to the contrary I would have to believe that Allis Chalmers did in fact build their own transmissions.
