crank shaft "timing stub"

[90_eclipse]

So one of my buddies ended up actually over torquing the crankshaft sprocket bolt, and cracked the balance shaft sprocket. We had a very hard time taking off the sprockets and we were left to find that the crank shaft "stub" seems to be pushed back making a right-angle triangle vs a flat rectangle. any ideas?

That's a key and it's removable. Straighten it up.

that's a tough one to overtorque. It's over 100ft lbs if memory serves.
