I don't have the club's 1932 Ford books, so I'm wondering if someone could please tell me the standard gear ratio for the 1932 Model B? Is it a 4.11?

I can't directly answer your question, but I'm sure it depends on the motor in the car. For someone to answer the question they would need to know if it's a 4 cylinder or a V-8. This message was edited by trjford8 on 6-14-20 @ 7:52 AM

Thank you, It is the 4-cylinder. A tudor sedan.

Unless it is a very early axle the ratio will be as you thought, namely 4.11. The ratio is normally stamped on the center section near the connection with the torque tube (4.11 being stamped 9-37). In very early production, Model B open cars and commercial chassis had rear axles with a 3.78 ratio, Model B closed cars had 4.11 ratio axles, and V8 passenger cars had 4.33 ratio axles. In late April, the 3.78 and 4.33 ratio axles were discontinued and all 106" wheelbase vehicles were equipped with 4.11 ratio axles for the rest of the model year, including the new 18-prefix axle with a straddle-mounted pinion gear released late in the model year. Given that yours is a Model B closed car, it would have been built with a 4.11 ratio axle whether it was an early, mid-year, or late production vehicle. Of course over the last 88 years the rear axle may have been changed at some point in time. This message was edited by 3w2 on 6-11-20 @ 8:10 PM

Oh Henry, that's interesting. I came across a service bulletin that appeared to be from around March 1929 proclaiming that Ford would be discontinuing the 10-37 differential for Model A production and only manufacture the 9-34 (3.78). So it makes sense that those would bleed over into early Model B production. But I wonder why they reduced the rear end from 3.78 to 4.11 in the Model B when they raised the horsepower of the 4-banger from 40 to 50. I guess they weren't exactly putting "highway miles" on cars back then and needed the torque. Thanks for the info! It is appreciated.

I've read that the "rated horsepower" in many cases was invented by advertising needs rather than reflecting actual fact. Alan

Alan, And perhaps the advertising guys invented the dynamometer test results on file at the Benson Ford Research Center; not likely however.
