Removing Shaft Keys From Sterling Rotor.

[connerdstines]

I recently got myself a Sterling M-5. The shaft keys holding the rotors on are heavily corroded and they are unbelievably tight. Am i screwed, or is there still hope in removing these without destroying the siren?

Your best bet would be to heat up the center of the choppers so the aluminum expands to the point to which they can be slid out. Whenever I can't get a chopper off, I take it to a motor shop and that's what they do.
