Step 7: Close the Shoulder Actuator Housing
Join parts 400_13C and 400_14C around the actuators with the carried socket bolts and secure part 400_13C to actuator ID 15 with three threadlocked M4x8 socket bolts.
Parts needed
| Part | Count |
|---|---|
| Actuator-housing assembly containing part 400_14C | 1 |
| Prepared bearing housing containing part 400_13C | 1 |
| M4x8 Socket Bolts | 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 the 4 – M4x25, 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 – M4x25 socket bolt you just remove and then secure it through the aligned hole from Part .
Tighten the 3 bolts we have put in place in Step 3 around the circumference of the part . Don’t over tighten it, it is just meant to secure the actuator in place.
Take 3 – M4x8 Socket Bolts 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 each of the 3 – M4x8 socket bolts,
- apply threadlocker,
- then tighten them back to secure Part and the actuator together.

Step 6: Secure the Shoulder Actuators
Secure actuators ID 14 and ID 15 to part 400_14C with threadlocked M3x12 flat and M4x8 socket bolts, then tighten the three retaining bolts.
Step 8A: Connect and Join the Shoulder Assemblies
Connect the XT30 connector to actuator ID 14, solder the corresponding cable conductors from actuators ID 13 and ID 14, and join the shoulder subassemblies.
