With the crank-bolt removed, check the bolts in the kit to make sure the threads match those in the balancer. After applying lubricant, thread the center screw partway through the puller and rest the swivel against the end of the crank (convex side against the crank). Now match the pointed end of the center screw (already threaded through the puller) to the dimple in the swivel. Hold everything in place and thread in the puller bolts (with washers). Make sure the three bolts are in evenly and at least halfway so they wont pull the threads out of the balancer.
