An often overlooked part of an engine build is balancer fit. With the vast array of aftermarket cranks and balancers, the chances of purchasing parts that are exactly right are slim to none. Most quality balancers are made small, to allow you to properly fit the balancer to your snout. If the balancer is tight and you force it on, you will ruin the crank. If the balancer is loose and you run it, you will ruin the crank. If you buy a new crank, you should buy a new balancer, or new hub for your existing balancer and have it fit properly. At the least, check the clearances and see what you need to do.
