2001 XJ 4.0L here. What is the bolt that goes through the center of the idler pulley for? It seems like you would just turn the adjustment screw to vary the tension on the pulley, and not mess with the bolt. Does it actually hold the idler pulley in place, or does it just lock it down after adjustment?
