Description of Eccentric Bolt





1. Both ends of the eccentric fulcrum bolt, i.e. the threaded section and the head are concentric with the holes in the crossbeam fulcrum flanges. However, the center section of the bolt (arrowed), which retains the wishbone rear bush, is eccentric to the two ends of the bolt. When the bolt is installed; rotation of the bolt will cause the lower-wishbone rear arm to move in and out. A raised strip (arrowed) on the bolt head flange indicates the position of the bolts eccentric section, to aid positioning when adjusting the camber. The function of the eccentric bolt when it is rotated, is to increase or decrease the distance between the lower-wishbone fulcrum center at the crossbeam and the ball joint center, therefore altering the camber angle.
