Alternator Casing Cracked

[meltdowner]

Small crack in the alternator casing, it's still functioning however I'm thinking about replacing it anyway. If I'm replacing the alternator, would it make sense to replace any other maintenance items in the process?

Serpentine belt, tensioner pulley and idler pulley if never done.
