I have virtually no knowledge of any 9k engine prior to model year 94. What I do know is the Woodruff key is absolutely critical in keeping your timing correct. Also the chain sprocket, oil pump gear and the crank pulley are held together and prevented from roatating relative to one another by the Woodruff key as much as the proper tightening of the crank bolt. If you tighten the crank bolt to spec, the Woodruff key will not be loaded in shear (at least not as much).
I'd not touch the crankshaft. I'd replace the key and tighten the crank bolt to spec.
