Has anyone done this? I was changing the serpentine belt on my 93 300E 2.8L, and noticed that the pulley edge is slightly dented in towards the belt, which had caused damage to the previous belt. I couldn't figure out how to get the pulley of.

There is a tool to hold the pulley from behind and prevent it from turning while you removed the bolts from the pulley. That of course is done after you remove the fan. Once forum member posted this picture...

I hope this answer your question.
