Thanks. The next time I clean the well I'm going to see if I can grasp
it with a pliers and remove it.

Just be gentle; pull straight out while giving it a bit of a twist and it
should come right out. For some reason replacement impeller shafts for the
500 are harder to come by than the universal shaft for the smaller AQ
series.
