Step 3: Install the Neck Yaw Actuator

Take actuator EC-A4310-P2-36 (ID 24) and lay it flat on a surface such that the actuator shaft is facing toward the ceiling, the port is at the bottom.

Take part 100_03A and align the 4 inner holes with the threaded holes on the actuator.

Take 4 - M3x12 Flat bolts and tighten it lightly into the 4 holes on part 100_03A to align it with the actuator.

After the parts are aligned:

• remove each of the 4 – M3x12 flat bolts in a star formation,
• apply threadlocker,
• then tighten them back to secure Part 100_03A and the actuator together.

Connect one connector of the 200 mm double-ended XT30 (2+2) cable to the specified neck yaw actuator port, then route the cable through the cutout in part 100_03A. Leave the free connector accessible for the neck pitch actuator.

Connect one connector of the 600 mm double-ended XT30 (2+2) cable to the other neck yaw actuator port and leave the free connector accessible for the RPU connection.

Take the actuator and part 100_03A and align it with the neck on part 100_01C. The double-ended XT30 (2+2) - 600mm cable should be routed through the neck to the inner hollow of the body. The double-ended XT30 (2+2) - 200 cable should be routed through part 100_03A and face forward toward the chest of part 100_01C. Then, carefully lower down the actuator into the neck hole of part 100_01C.

Take 6 - M4x12 Flat bolts and lightly tighten into each of the holes on part 100_03A to align Part 100_03A with the neck portion of part 100_01C.

After the parts are aligned:

• remove each of the 6 – M4x12 flat bolts in a star formation,
• apply threadlocker,
• then tighten them back to secure Part 100_03A and part 100_01C.
