D12C accessory drive pulley

I have a 2001 Volvo vnl with a d12C motor. I was about to load today when I heard a funny squeal noise coming from my engine so I opened the hood and saw that one of my pulleys was wobbling.

I did as much research as I could, and found out that it’s the accessory drive pulley, from what I can tell drives my fuel pump.

I can’t find a repair guide anywhere on this, but would like to attempt it myself, as I consider myself pretty mechanically inclined.

Does anyone have or know of a place that I can find out what is involved with this repair? I’d rather have some sort of guide or troubleshooting done versus just taking it apart and guessing as I go.

 

I appreciate your help. I saw this, unfortunately, my problem isn’t my fuel pump, it’s that pulley. I don’t know if there’s any special tools or a method to do this, or what I should be looking for, this was only part of the info I needed.

 

I’m sorry, I must’ve misread, if they’re all one unit I see what you’re saying. I was hoping I didn’t have to pull everything off of the front of the truck, lol.
