The part attached to the belt is the pulley. It should spin freely when the belt is not installed. The front plate is the clutch. It is linked to the compressor and only turns when the electromagnetic coil behind the pulley is engaged, forcing the clutch to retract and contact the pulley.

well there's ALOT of play in the pully and metal shavings and dust are coming from it. I can wigle it back and forth in any direction.

If that's the case I'd venture to say the bearings are shot. If you spin it, does it make any sort of grinding sound?

A new pulley/coil/clutch pack can be had new for about $100. It might take an hour to replace with the right tools.

You can get just the pulley, but the clutches do wear out eventually. IMO it's worth the extra money to just get the entire assembly and replace all of it while you're there since you need to remove the clutch hub to get at the pulley anyway.

The Motorcraft P/N for just the pulley is F5VY-19D784-A and goes for $75 on Rockauto.com. The entire clutch pack assembly is F5VZ-19V649-AARM and runs for $115.

BTW - be sure to remove the snap ring holding the pulley on after you get the clutch off. :)

One of these:


You can see the snap ring underneath all the grease; the part you stick the tool into is at the lower right in the pic.



Snap ring pliers can be had at any auto parts store for under $10.
