So im changing my water pump i rented the pulley puller from oriellys i put the 2 pieces on the snout of the pulley slipped the sleeve on then threaded in the bolt and start tightening then the bolt just gets tight it doesnt pop off the pulley what am i doing wrong?

That looks like the power steering pulley to me the water pump one should unbolt with 4 bolts and just about fall off.
