1932 B banger with a Model A flywheel ?
Hey guys, my recent 32 Truck B banger when pulled had a Model A flywheel installed. Apparently the flywheel fits and was ran this way before I acquired the truck. I could never confirm how well it ran since I only idled it due to other mechanical and leaks issues with the motor. I plan to continue using the flywheel if possible when I rebuild the motor but would like to know if anyone has done this without any issues like balance or chattering. Pros and cons ? Finding a 32 flywheel is near impossible and Model a flywheels are plentiful. Thanks .

Re: 1932 B banger with a Model A flywheel ?
Other than being unnecessarily heavier, there shouldn't be a problem with a Model A flywheel on a B engine. I would think that B flywheels would not be that hard to come by given that nearly 300,000 of them were made from 1932-1941 and unlike commercial/truck radiator caps, they did not fall off or get left behind at gas stations.

The A flywheel can be lightened to B specs by a machinist. Newc

There is a 11 lbs. difference between the Model A and the Model B ...63lbs. vs 52lbs. The "B" had a counter weighted crankshaft.
I am running a Model A flywheel that weighs 26 lbs. Many Model A parts suppliers have "lightened" flywheels for sale. |

No. The first Model B was in 1932 and it did not have a counter balanced crank, just a bigger crank than an A. They came out with the counter balanced crank in 1933. They were interchangeable with the early one.

IMHO...no need for the 60lb flywheel, that was for lugging thru mud holes we do not have anymore. I like the lightened v8 flywheel with a 9" disk and v8 pressure plate. Easy on the left leg, and quite peppy compared to the 60 lb hunk

Like the flywheel Burtz is selling for its five-insert-main bearing Model A engine.

Re: 1932 B banger with a Model A flywheel ?
I have always heard it referred to as a C crank. The one I ran was a Russian C crank.

Re: 1932 B banger with a Model A flywheel ?
The 'C' designation for '33-'34 fours likely comes from the mistaken interpretation of the 'C' on the cylinder head. In the case of the head, the C is there to distinguish it from the higher compression B Model A head. (Evidently Ford did not think that its dealers' parts counter persons were very smart, further evidenced by casting part numbers into '32 V8 heads, at least for a little while.) There is nothing in Ford's archives that supports the use of a C as either a prefix or suffix in the 1932-34 fours' part numbers.

The Model C was used in Britain, it looks kinda like a 7/8 scale 35 Ford. .

The part number of the counterbalanced crankshaft was B-6303-B. Not a C in sight.

Re: 1932 B banger with a Model A flywheel ?
It was long ago but I thought the A flywheel rubbed on the B transmission case. Maybe a bad memory or a build up of tolerances in a particular case.

Re: 1932 B banger with a Model A flywheel ?
The C was likely the engineering change for the different water pump from the original A design. This would have been the 3rd change in the A-6050-A lineage but it was for a new model of engine so the prefix changed to B. The suffix B high compression heads never made it into the green bible chassis parts book likely because they came so late in the model A production. The A-6050-B heads weren't produced till 1931. The heart shaped chambers and the big "B" give them away. A-6050-A heads had no markings till production for the model A cars was ended. After that, Ford generally just cast the Ford trademark on the surface with a date code. They may have produced them till the end of the model A engine production just before the start of WWII or they farmed them out like the blocks, ie the diamond blocks. Ford also produced the AF-6050 heads for the UK model AF production engines.
Since the model A had no markings on the heads from standard production, putting the "C" on there made them distinctive from the model A but a quick look at the water pump mount flange is enough for me. |

Re: 1932 B banger with a Model A flywheel ?
With respect, the A-6050-B cylinder head, high compression, is indeed listed in the chassis parts catalogs, just not one published 17 years later. It is shown at least through the 1934 version. Further, a '32 four-cylinder water pump's part number was B-8501 and that of the '33-'34 fours was 46-8501, not A-8501-C.

Re: 1932 B banger with a Model A flywheel ?
I'm not surprised, when parts were obsolete, they didn't make it into the green bible. The early part books likely were different colors over the years.
Municipalities that used the model A as a Police vehicle likely used them for a long time due to the depression years. It probably didn't take them long to go to the V8 for pursuit cars. That's what a lot of criminals were using. It would be interesting to know how many B heads were made. They were copied in later years. Last edited by rotorwrench; 02-17-2023 at 07:17 PM. |
