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.

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 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 – 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.
