OK, you're halfway there. Don't drop the ball now by trying to use the center bolt to install the damper. You'll strip the new thread in the process. Borrow or rent a balancer installer that bolts onto the end of the crank and uses a heavier thread to push the balancer into position, or heat the hub as described and gently tap it into place. The threaded crank just allows you to secure the pusher tool.
