Default Crank wear??

I have a OS TZ and the crank has .0005 wear out of round on the crank pin. How far until it is time for a new crank?

It is come up to 0.012mm and I wouldn't vorry about it for now, but defenetly it will go more way faster then from full round to this number, so as Doctor say keep eye on it and it should last for some more time.

.0005 is in thousanths of a inch not .0005mm.

Are you saying that it can wear .12mm out of round before I need to worry about changing the crank? .12mm is about .0045 thousanths of a inch .012mm is so small I don't have anything that will read it.

AMGRacer pointed absolutly right-it is 0.0125 mm and if you have this elliptical size diference then you are OK.
Sorry, I am using metric system because I think it way more convinient then SAE.
