Step 6: 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.
Parts needed
| Part | Count |
|---|---|
| Actuator housing assembly from Step 5 | 1 |
| Bearing housing from Step 3 | 1 |
| 3 | |
| Threadlocker | As needed |
Instructions
Put the part (the part with the actuator secured to it) flat on a surface, such that the actuator is facing upward toward the ceiling.
Slowly remove 4 of , one bolt at a time around the round surface edge surrounding the actuator. Do it slowly so you can avoid the square nut from falling out of the slots.
Put the Part and Part together such that the actuator is well encapsulated and all the holes on the surface aligned with each other.
Take each of the 4 bolts you just removed and then secure it through the aligned hole from Part .
Tighten the 3 bolts we have put in place in Step 3 Instruction 3 around the circumference of the part . Don’t over tighten it, it is just meant to secure the actuator in place.
Take 3 of and lightly tighten into the three hole on the longe end of part to align the part with the actuator.
After the parts are aligned:
- remove 3 of one at a time,
- 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 (2+2) cable connectors to actuators ID 19 and ID 20, and route the single-ended cable through actuator ID 20.
Step 7: Connect and Join the Shoulder Assemblies
Connect the XT30 (2+2) connector to actuator ID 19, solder the corresponding cable conductors from actuators ID 18 and ID 19, and join the shoulder and upper arm assemblies with plates 300_03A and 300_01A and threadlocked flat bolts.
