The apparatus may include a lock nut gauge, a zero setting gauge extending into the lock nut gauge, a lash setting gauge extending into the zero setting gauge, and a bit stem extending through the lash setting gauge. The bit stem may include a bit which is used to rotate a tappet screw that sets the lash. A key extending between the zero setting gauge and a scroll channel in the lash setting gauge may be used to control setting of the tappet screw, and thus the setting of lash.
