Tighten the bolt while simultaneously spinning the pushrod with your other hand. Once the slack is taken up, use a wrench and an Allen socket to tighten the bolt. It should not take more than a full turn of the wrench to tighten. If it takes more than one turn, you will need to remove the rocker and install a shim (shown in the previous photo) between the aluminum stand and the stand guide. A small shim was needed for almost of our rockers.
