I missed your post question. the removal I use a electric torque gun with the belt on to remove the studs . I rotate the crank pulley so that the pointer is up. this is so the engine is at TDC or 180deg out.when doing the opti.

I also used a file the first time I removed this and put antisieze on the back side and on the hub assy. did this a few times , first time is the tough one.

I would not use a brake drum puller .. you should pull on the inner portion because the outer portion is with a rubber bonding .. pull on that . it will damage it and others have had this happen .. make sure the belt rides properly on pulley..
I used a typical steering wheel puller used penetrating oil and wire brush to clean up the hub area first.
