Crackshaft service hours.

Time before overhaul is measured not only in hours run but also in calendar years.

For 582: 

How old is your 582 engine?

(If you are not sure, we can look up the production date for you based on the engine serial number)

PS: This information  is published in the maintenance manuals, it's a good idea to become familiar with those...

Thank's for reply. 

My engine serial is 5307094

The cuestion is, if it is necesary to change cranckshaft on a overhaul since that hours.

It's necessary to do an overhaul once the TBO has been exceeded. The overhaul process includes tear-down, inspections and checks of all tolerances, and that process will determine exactly which parts will need to be replaced...
