A control arm clamp and shaft assembly for fine adjustment of angular
position of the clamp on the shaft. An adjustment bolt and nut includes a
socket head located eccentrically relative to the centerline of the bolt
shaft so that the bolt head can function as a cam lobe when the bolt is
turned. The control arm clamp includes a primary shaft clamping means. The
shaft has a diametric bore. The control arm clamp has an axially-slotted
opening into which the bolt head fits and engages opposing walls of the
opening. When the primary clamping means is loosened, rotation of the
adjustment bolt head against the opening wall causes an angular rotation
of the control arm relative to the shaft. After the control arm is
repositioned, the primary clamp is retightened and the adjustment bolt nut
is tightened. The adjustment bolt may also take the form of a removable
pin.
