Guidance needed on removing A/C rotor
 

My 2001 xlt 2.4l needs the ac clutch and rotor pulley removed. I have the replacement and removed the clutch and the snap ring.
I got an Evertouch A/C Clutch hub puller & installer kit. I think the piece below is called a Field Coil Assembly? But I’m not sure how to use the tool or if it’s even for this part. I’ve seen a video where it’s removed with a crowbar. I hit it with a penetrant but still unable to pull it off manually. what do I do?
