No, they don't all do that!  Maybe a few 0.01mm, but not much.

Make sure it isn't about to come off the end of the crank!  There's a
large bolt holding it on the crank, whinh should be tight.  the pulley slides
a long ways onto the crank and is located via a woodruf key - so if the
bolt's loose seems to me it could slip off the end of the crank while
it was still being driven by the key - large wobble ought to occur just 
before things come loose.  (at least it's a theory).

If you need a pulley, let me know maybe I can find one.
