how to seperate a clutch fan...out of the car

hey guys

I am installing a A/C compressor on the 360 that will go into the duster
when I got the compressor the clutch was included but not mounted to the compressor (makes sense, there is no way to take it off the bracket with the clutch on)

now, here is my problem, I cant seem to figure out how to take the clutch apart so I can mount the backing plate back unto the compressor

any thoughts?
