Quickly grab the hot balancer with your wife's best towel, duck her blows, and run out to the garage. Place it on the crank, place a 2X6 on the front pf the balancer and then hammer it on. Metal swells when hot and shrinks when it cools off. Trying to hammer on a cold balancer runs the risk of getting it 1/2 the way on and then not being able to move it.
Won't this cause damage to the inertia ring?
