I googled "Willys Crankshaft Crate" and the only crates that popped up were a Chevy V-8 crank and a Spare DB 605 crankshaft (Meserschmidt 109), appearing fresh from the machine shop.
Never store a good crankshaft horizontally; only vertical. They will warp. Of course, if you never plan to use it without re-grinding, then store it any way you like.
That's an interesting statement. Especially considering they are left lying horizontal for the better part of their entire lives. Crated they are usually horizontal as well. Do you have any data to support your position? _________________ Wes K

Storing crankshafts vertically is a common assertion; I have no opinion if it is true or not. The concept is that a crankshaft is designed to be supported on its main journals, like the example in the crate. In use, of course that how it is supported. Again, the theory is if the crankshaft is stored horizontally on the counterweights, it is subject to unbalanced loads and can bend over a long period of storage. You can find strong opinions from mechanics, engineers, and shop foremen on both sides of the issue. Crank machine shops typically store vertically, although this may be for convenience and space saving. Flathead Ford engine rebuilders recommend vertical storage, or V-block mains supported horizontal storage.
I currently store mine vertically, bolted down to a wood deck, coated with Cosmoline and covered with a plastic bag. But, I am building crates similar to the photo example with wood V-blocks supporting all 3 main journals.
changes the meaning of dpcd67's original post significantly. Now since most cranks do not have symetrical counter weights it stands to reason they may bend unevenly due to loading when stored for very long periods resting on their counterweights.
However when properly supported at their main journals this is not an issue.
The reason why I do not store cranks vertical? The risk of damaging the crank when stored vertical is much greater because they are easily knocked over. _________________ Wes K
