If a crank broke, you just went to the junk yard and bought another engine or you went to the used car lot and bought another car. It depended on how much money you were making at the time. During the war, folks had to make due with what they had since auto manufacturing dried up but there were still used cars available from service men going overseas. My Pop sold his 35 Tudor in Florida before he and his crew left for the ETO. He bought a 41 Tudor after he got back in late 1945.

Adjusting the bearings was an accepted service procedure back then. In fact, the Model A Instruction Book says "If a bearing has become loose it should be adjusted by an authorized Ford mechanic." Many A's, probably most, needed at least a valve and ring job during their lifespan which included adjusting the bearings unless it was a backyard job. My question is, How many broken cranks resulted from the resulting "bowing" effect? In spite of all the adjusting that went on, A's did not have a reputation for breaking cranks (such as Chevy's reputation for broken axles at that time).

To answer your question, on what we have found, was about 33 cranks, in about 55 years, not broke, but cracked, and not usable. We have never used any crank shaft, with out magnafluxing it first, on any kind of car.

Thanks,

Thanks for the info, Herm. That's a low figure, for sure. And I imagine a lot of the engines that hit your shop have been ridden hard and put away wet! How many engines would you estimate have gone through your shop in those 55 years?

Give, or take 500 engines. Way more then that in just babbitt jobs. There was a Guy in Minneapolis, that would bring, 18 to 22 blocks at a time. He would do the machine work, and then brought them for babbitt. He used to work for Gopher, engine, nice guy.

Model T's, about 400, not counting Babbitt Jobs.

33,000 Spun poured A, Rods, That many , or more in Model T rods.

For many years we had 5 to 6 full time Employees.

That is not counting all the other makes of cars, and tractors, and all kind of industrial machines.

One thing I can brag on is, in 55 years to date, we have never lost a bearing to bad workmanship. The reason for that is if there is even a small imperfection, that won't bother, it goes back, for repouring. At the time of finish machining, whether the bearings are in finished Semi, or completely done.

Thanks

Herm.
