Remove the gripper assembly from the "C" bracket. Remove the Little Grip from the Little Grip Connector. Set the "C" bracket and Little Grip Connector Lexan aside — they will not be used with the wrist rotate.
Figure 1.
Drop the HS-85BB into the wrist rotate bracket from the top as shown. Refer to the attachment diagram below. Make sure the servo is in center position and remove the servo horn — be careful not to turn the servo shaft.

Figure 2.
Attach the Little Grip to the HS-85BB servo as shown. Push it onto the servo and secure with the servo horn screw. Tighten snugly.
Figure 3.
Align the HS-422 servo to mid-position with the gripper halfway open. Remove the servo screw and horn. Slide the servo into the gripper from the bottom — wiggle slightly if needed to seat properly. Replace the servo screw, tighten down, then unscrew half a turn. Too much friction can bind the servo.
Figure 4.
Slip the gripper assembly back onto the arm assembly and attach with two #2 x .250" tapping screws. Add a 6" or 12" extender cable (or both if necessary) to the wrist rotate servo and plug into channel 5 on the SSC-32. Use wire ties to tidy up the wires.
