By observing the above values the full movement of the side thrust pin will be available to cover the tolerance of the workpiece. For inserting the side thrust pins the use of a mounting tool GN 715.1 or GN 713.1 is recommended. Eccentric bushings GN 715.2 are a tooling accessory for GN 714 / GN 715. They enable a precise optimum setting of side thrust pins. This allows an adjustment to l 0 to accommodate for instance a larger tolerance range on a workpiece.
