Help Requesting Identifying Pulley

Hello All;
So I brought My E55 into a firestone dealer to get an alignment after hitting one of the many New England pot holes.

the tech comes back to me about 15 minutes later and asked me how the car is performing.
It's been ok I guess. Is it down on power? come to think of it yeah it is.
It's been winter and snow. Did I mention we have a had a record amount of snow this year? So I really have not been driving the car hard for months.

I recall doing the ECU reset about a week or so ago cause I did notice the lack of sprint on the throttle.

He showed me this:

The SC belt had come off, becasue this pully had come off!
Well THAT would explain the lack of power.

So I have searched for a part number for tis pulley but I don't really know what it's called. So without that I am a bit lost.

Does anyone have a part number and where to buy this ate other than a dealer?

Also could someone take a picture of theirs so I can see how it should be oriented, including the Belt path would be a nice bonus.

I also noticed that the c-clip is still in tact so I'm guessing the inner bushing is what failed.

Any thoughts as to how hard this maybe to install myself?

thanks for any help you can provide
