Here's a question we've received several times via email, pm, etc.
Q: I just received my pulley and it looks like it's damaged.
There seems to be a nick/notch/ding on the edge of the pulley.
A: Your OEM crank pulley has the same mark in the same location.
This is called a "timing mark" and is used to time the engine should service ever be needed in the future.
