I think your prefix numbers (72 and 76) are date codes, or whatever and MEANINGLESS to what's going on here.

Also, you are missing a digit in the first part number you posted.

A crankshaft cross reference I found lists the following crankshaft numbers as interchangeable: 3055045R2, 3059510R1, 313295632, 3132956R, 3132956R3.

You say you are working with a machine shop, why not have them evaluate the mystery crank, checking exact journal sizes, and to be sure it's ground concentric and is not bent?

You can usually view the official FIAT parts website on-line at the link below to see what part numbers are shown in the official parts catalog, unfortunately, it seems to be down for maintenance at the moment.

Plasticguage is cheap. Also easy to have one bearing in crooked. Did you turn crank every time you tightened one main. Or rod. Are they all to big. Or just one.

May not have any bearing on what you are doing but I have an industrial 464 and find out that a lot of things on the farm tractor 464 are different.
