If it were mine, I'd remove the crank from the engine and take off the flywheels then take the bare crankshaft to a good machine shop and get it straightened.

While you're about it, if there are any scores or roughness, you may want to have them polish the journals. Polishing shouldn't take off enough metal to worry about. Just remove a shim or two to compensate.

Take care - Elden
