I didn't pay attention the direction of the woodruff key as it came out (I was just too happy that I finally got that dam pulley bolt to break), so I need a visual/description of the way it is supposed to fit in the slot. One side of the key is different from the other side, but the width is similar so I'm afraid that I might get it there wrong, become stuck, and then add more days to this already dreadful job. Can anybody help me?

 

Should be shaped like a half moon if I am not mistaken. Anyway, the round part goes against the crank shaft, flat against pulley.

 

Ah I see now, thank you for the reply!
