When they have been on form more years than they should, they sometimes get stuck.
Easiest thing is take a sharp chisel and split the impeller between the vanes. Right over the key is the best place to do it, it's not only thinner there, but if you go to deep you hit the key, which is easily replaceable.
Then just clean the shaft up, new impeller and key, and you are good to go.
