B tranny to C torque tube

When the CA came out the B and CA then shared the same torque tube. As did the B and C before.
 

I saw an interesting Allis "G", with Allis "B" trans and final drives/wheels..
Had a modern 4 cyl. injected auto engine and full 2-way Hydraulics..set up like a small road grader..
Looked like it could have been a New Factory product..!

Looks like a worth-while project..

If you want to hear of strange "will it fit" stories, I recently agreed to purchase a tractor that has D14 axles and wheels, D12 rear reduction housings and transmission, B engine, CA front end. It didn't have any sheet metal on it the last time I saw it, but the seller said he has sheet metal to go on it, that is included in the deal. Going to be interesting to see what it looks like, lol!
Allis used a lot of interchangeable parts, obviously!

B C transmission except for what they did to the front.

Not any difference between the B and CA engine blocks and they bolt directly to the D series bell housing. The B, C or CA fronts will bolt directly to any of the blocks. It would need the CA radiator cover to fit. Loss of HP is the bigest change. You can use the 3 7/16 pistons in all of them but the B,C and CA's have a 3 1/2" stroke and the D has a 3 7/8" stroke.
 

Yes, the old man said he had to eliminate that gear reduction..
He had to make completely new gear shifter linkage, because it is UNDER the seat(I have pictures somewhere here of that tractor) and model "B" rear end and wheels..eliminating the weak differential of the "G".
It looked "right" and had a more substantial look than a "G", with the cast rear wheels.
He said he used basically all AC parts to convert it (except for the Hydraulics.
I would think this would be a popular conversion..
 
Using the B final drives would have slowed it down a bunch with the engine on the back going thru the G bell housing gearing. Probly could have used the Allis small engine just as easy. I can see it being a useful project.
 

That must be why he said the front reduction had to be eliminated.
It looked very sharp, with the grader blade across the center, with small Hydraulic cylinders (one on each side-vertical)for blade tilt and height and a perfect Clear-Coated Persian Orange..
I think it was at the Steam Show in Plain City, Ohio (Pastime Park) last year..

The gears would have most likely been in the way to make the frame solid enough for the grader on the front. Those slow gears are for just that slow. The little one will not handle a lot of power.
