The correct way is an installer... Impacting th crank snout isn't a good idea. The thrust bearing is all you have to stop the crank from moving, and it's force in a direction the crank wasn't designed to take. Same with the balancer itself. The crank bolt isn't designed to pull them on. If it's a lose fit it will work, but a lose fitting dampener sin't going to work well either. In many cases the bolt by itself can't get it all the way seated - especially true with a new balancer and/or a new crank. Summit sells the installer/remover pkgs for $50-100 and you'll never need to buy it again.
