The pulley is bigger than the balancer. That's why I recommended taking out the four bolts holding the pulley to the balancer. The groove in the balancer is probably not lined up with the key anymore, keeping it from going back on easily. Try a little rotation to see if you can line them up, or just unbolt and split the pulleys from the balancer.
