I would have thought that using a blowtorch would make the crank expand (thus making the hole smaller) and make the spindle expand which would make the two even harder to separate.
I would try freezing it so that the hole gets bigger and the spindle smaller.
Don't try to hammer it if you do though as the metal will be more brittle.
