| C and B steering boxes steer opposite of each other . My guess is somebody replaced your B box with a C box , not knowing this . |

| Any chance it’s a C with a B front end? Sounds like it has a C steering gear box in it if it’s for sure a B. |

How would I tell the difference? I do see the gear box is not fully bolted up tight, so maybe there something to this idea.

The tractor serial number should include a letter for the model. It might be that the B and C shop manual can help you identify the parts. http://geraldj.networkiowa.com/Trees/Allis-Chalmers-G-B-C-CA-Service.pdf" rel="nofollow - http://geraldj.networkiowa.com/Trees/Allis-Chalmers-G-B-C-CA-Service.pdf Gerald J. |

| Pictures, pictures and more pictures. After 80 years and B C parts being interchangeable unless you know the slight differences in B and C parts it is hard to tell what you may have. The B steering box has a shorter out shaft with a constant spline. The C steering box has a longer out shaft that has a larger diameter spline that is not constant exact splines. They can bolt up tight to the torque tube because both the B and C uses the same torque tube. This is only one of many slight differences in parts that will interchange. |

The Arm on a B box points down. A C arm points up. Makes the mismatch you describe by using a C box on a Arched Wishbone B Front axle used on All 1938 Bs. Any B Gemmer or Ross box will correct the problem.

How Correct a 38 are wanting your Highschool project to be. I helped a friend do up a Early B like yours. #751. I have a extra pair of the correct F&H Cast Iron front wheels for your early 38 B if yours don't have them. Being the 816th B off the assembly line it came with 3 piece rear rims bolted to the wheel with 2 3/4 Bolts and 2 3/4 eccentrics. They may be long gone. Correct rear tire size should be a 8-3 x 24. By requesting a copy of a early B parts book as a guide for a accurate restoration would help you tremendously . Your B should NOT have a metal seat back. It was wood padded and covered with canvas

OK, I'll bite. I had never heard of this issue. But I am trying to get my head around how it would feel to attempt to drive a tractor that has been set up like this!:) My guess is that eventually it might become OK in your brain that it responded back wards?? Kind of like getting off a Allis WD series with the hand clutch and getting on a John Deere with the opposite working hand clutch??? I Think you should find the correct steering box and add that to the list. Yes we need tractor pictures of the project too.

| Looks like a B steering box from that angle. Could you take a picture showing the linkage from the front to the steering box including the front axle? |

like Dick said........ look at the front end linkage.. Does this gear box have a long rod that connects under the radiator, or does it connect to the left front wheel king pin area ? ------------- Like them all, but love the "B"s. |

In the summer of '68 I worked as a helper millwright, during change over. Some of the fork trucks there steered backwards, to go right you turned the steering counter clockwise. Dusty ------------- 917 H, '48 G, '65 D-10 series III "Allis Express" |

I will resize your pictures if needed so we can help figure out what is going on. A side picture of the tractor might be a help. |
