Air Pump for w201? ('91 190E 2.6)

Was wondering if anyone had experience with problems on the 190E 2.6 Air Pump. The pulley attached to mine seems to have unaligned itself making the belt smoke and awful noises. It was running but (next day) when I got a tow it started and died. Won't start now.

It doesn't appear that the main bearing of the pump is unaligned but rather that the pully is coming apart from itself. Is it possible that I only need to replace the pulley?? If you're familiar with this issue, you know I'm not looking forward to replacing the $1000 pump.

Any and all help/info would be appreciated.
