97 2.2 cant remove harmonic balancer doing timing chain

hi i working on my sisters car i trying to do the Timin chain as the engine quit and the lifters arent moving so that has to be timing chain

now i have gotten the power steering pump off and the tensioner wheel i left alternator on since i dont see u need to remove it? and the big plate still left on as it holds the car up

now i working on draining the oil and i hope the oil pan just drops and pulls away

but the problem i on now is i got the 3 bolts off the harmonic balncer pulled the pullie off

then i put my harmonic balcner puller on and tightend the 3 bolts till they all way screwed in but when i use the puller i cant get this hub off it just damages my center shaft puller shaft
why is it not coming off? something else holding it on? or what can i do to get it off?

i just stripped the shaft of my harmonic balancer puller
what the hell is holding this hub on? like how do i get this damn thing off
