Step 6: Secure the Shoulder Actuators
Secure actuators ID 19 and ID 20 to part 300_14C with threadlocked M3x12 flat and M4x8 socket bolts, then tighten the three retaining bolts.
Parts needed
| Part | Count |
|---|---|
| Actuator-housing assembly from Step 5 | 1 |
| M3x12 Flat Bolts | 6 |
| M4x8 Socket Bolts | 3 |
| Threadlocker | As needed |
Instructions
Take 6 – M3x12 Flat Bolts and lightly tighten into the 6 holes on the surfaces of Part to align the part with the actuator.
After the parts are aligned:
- remove each of the 6 – M3x12 flat bolts in a star formation,
- apply threadlocker,
- then tighten them back to secure Part and the actuator together.
Tighten the 3 bolts we have put in place in Step 4 around the circumference of the part. Don’t over tighten it, it is just meant to secure the actuator in place.
Align the threaded holes on the shell of actuator EC-A3814-H14-107 (ID 20) with the three hole at the bottom of the long end of Part .
Take 3 – M4x8 Socket Bolts and lightly tighten into the three hole on part to align the part with the actuator.
After the parts are aligned:
- remove each of the 3 – M4x8 socket bolts,
- apply threadlocker,
- then tighten them back to secure Part and the actuator together.

Step 5: Connect the Shoulder Cable Connectors and Position the Actuators
Seat actuator ID 19 in part 300_14C, connect the XT30 cable connectors to actuators ID 19 and ID 20, and route the single-ended cable through actuator ID 20.
Step 7: Close the Shoulder Actuator Housing
Join parts 300_13C and 300_14C around the actuators with the carried socket bolts and secure part 300_13C to actuator ID 20 with three threadlocked M4x8 socket bolts.
