Step 10: Install the Linkage Cranks and Cover

Take part 500_18B and align it with the threaded hole on the actuator nearer to the ankle on part 500_10C.

Take 6 – M3x12 Flat bolts and then lightly tighten it into the holes on part 500_18B to align it with the threaded holes on 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 500_18B and the actuator together.

Take part 500_17B and align it with the threaded hole on the actuator nearer to the knee on part 500_10C.

Take 6 – M3x12 Flat bolts and then lightly tighten it into the holes on part 500_17B to align it with the threaded holes on 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 500_17B and the actuator together.

After part 500_17B and 500_18B is secured to the actuators. We need to turn the knob such that part 500_17B (nearer to the knee) is turning to the left and part 500_18B (nearer to the ankle) is turning to the right. The two knobs should be parallel with each other because they serve as the linkage for the ankle mechanism.

Take the current assembly and put it on the surface such that the back side of the knee is facing upward towards the ceiling.

Take Part 500_13C and align it on the grove around the actuator hollows.

Take 4 – M3x12 flat bolts and lightly tighten into the holes of part 500_13C to align with part 500_10C.

After the parts are aligned:

• remove each of the 4 – M3x12 flat bolts,
• apply threadlocker,
• then tighten them back to secure Part 500_13C and part 500_10C.

Connect one connector of the 100 mm double-ended XT30 (2+2) cable to the port on right ankle A actuator ID 11 and the other connector to the port on right knee actuator ID 10.
