Is it common for Fiat to stamp their cranks with factory O/S's?
I have here a couple of 2L cranks that i was examining this afternoon for a friend and noticed one has [+0.254] stamped on the side of one of the counterweight flats.
Is this refering to an undersize on one journal? or all? Or maybe the crank was machined by a machine shop and they stamped it given it seems to be an imperial measurment not Metric?
I dont have a micrometer handy ATM to verify for myself but very interested to know if this is common.

Re: Crank markings
It is not common but it happens.
The stampings indicate an 'odd sized factory journal' and bearings are not available for them. This is very annoying and I do not think the factory should have ever approved the practice.
If the old bearing is good enough to re-use then do so otherwise that crank is scrap, you must not regrind them as it destroys the carburised layer (hardness and oil retention lost..)
