yeh just go rent a power steering puller tool from Autozone or something. They usually charge the cost of the tool and refund you 100% when it was returned. DOnt even bother trying to use a pulley puller b/c it will bend the pulley.
But im in Japan i dont have access to that kind of tools i see there is a allen wrench nut in the center do i take that out first then commence using a pully puller..
you can use a pulleypuller, just put the lips of the pulley in the groove, and let somebody put pressure on the lips with a socketwrench, so it won't slide off the groove...
