I’m guessing that is just a punch mark on the flywheel key, someone was either replacing it or trying to reposition it in the crank….

I think Don is right as far as what caused the damage to the key. Someone was probably trying to "find" the key location and rotated the flywheel around the crankshaft. In doing so they banged the keyway into the top of the key a few times and buggered it up. As long as you don’t find anything while working on it that looks like it caused the damage, I would assume someone did it while trying to remount the flywheel.

I would probably replace it, but truth be told, it is only there to locate the flywheel at assembly. The taper holds the position after the nut is properly torqued anyway. As long as you are able to properly seat the flywheel over the key, that banged up spot isn’t going to hurt anything. Just be sure there isn’t a burr that gets mashed between the flywheel taper and the crankshaft when it is installed.
