After you remove the bolt take the washer off it and re install it almost to the surface of the damper and use a 'elcheapo' steering wheel puller to slide the damper off. The reason to put the bolt back in is to use the head of the bolt for backing for the puller base. with out it for a backing the tip of the puller will fit into the crankshaft and do a number on the internal threads of the shaft. The damper will slide right over the bolt head without the washer on it.
