2006 Hyundai Azera
145k miles

I just climbed out from under this car. And with filthy fingers and brow furrowed in frustration, I bang this solicitation for suggestions into the keyboard. Here goes...

The field coil on the compressor is bad. I need to replace it. I have the car on jack stands with the compressor dangling from its hoses. I've removed the 8mm fastener in the center of the clutch plate. And that is as far as I have gotten.

The clutch plate will not come off. Period.

The pulley spins freely; the clutch plate spins freely. But the thing will not release from the spines that hold it to the compressor shaft. I've sprayed WD-40 where I can, whacked the clutch with a ball-peen hammer, and pried at the edges against my intuition ...all for the past hour, at least. Yet...

The clutch plate will not come off.

Unlike brake rotors, there are no holes in the clutch plate to thread in bolts to push the thing away from the hub (...stupid Hyundai).

I am officially stymied.
Suggestions? Recommendations?
