Yesterday when i was coming home my serpentine belt got ate up and ABC warning , battery warning and power steering went out. I pulled over and popped the hoop and noticed my crank shaft pulley broke in half I think what should I do about this and getting the running good again ? Could someone refer a part number ? As you can see there is stilll pieces of the inside of the pulley on the crank shaft the other 8 rip piece is still on there

Reason: Added question
A belt that breaks can cause a bad day. They are tough enough to damage other expensive parts so jt is important to inspect them during service. A common cause for this to happen is if you have an oil leak that damages and weakens the rubber. Since the belt did that, check the oil cooler lines.
Post is from March, so probably fixed by now, but my question is, did the belt break and destroy the pulley, or did the pulley fail and destroy the belt? I've had a serpentine belt fail but I had no issue with the pulley!
That pulley has to be replaced, The Mercedes part # is 1130300103. They are not inexpensive; look to spend $600 or more. The outer part being mounted to the hub by the rubber in between is intentional, as its purpose is not just to be a pulley, but to dampen vibrations.
