Step 11: Install the Linkage Shaft
Assemble the D-shaft linkage and mount it to Subassembly C.
Parts needed
| Part | Count |
|---|---|
| Foot-pivot assembly (currently documented in Step 12) | 1 |
| 6mm D-Shaft Stainless Steel | 1 |
| 6mm Bore 1-Side, 2-Post Pillow Block | 2 |
| Ball Joint Rod End | 2 |
| Steel Set-Screw Collar | 2 |
| M4x16 socket bolts | 4 |
| Threadlocker | As needed |
Instructions
Take the 6mm D-Shaft Stainless Steel and put 2 – Steel Set-Screw Collar onto it. Move it to the middle of the D-Shaft. Slightly tighten each set screw to keep the collar in place.
Take 2 – Ball Joint Rod End and put it one each on the right and left of the D-Shaft.
Take 2 – 6mm Bore 1-Side, 2-Post Pillow Blocks and put one each on the right and left of the D-shaft. Make sure that the bearing facing outward on the Pillow Block is sunken into the hole instead of flat against it. Please view the visualization in detail to install it correctly.
Take part and fit it onto part as shown below.
Then take the D-shaft component we have been building and align it with part and according to the visualization below.
Flip the assembly upside down so part is visible. Take 4 – M4x16 flat bolts and lightly tighten them into the holes on part to align with the threaded holes in the two pillow-block legs.
After the parts are aligned:
- remove each of the 4 – M4x16 socket bolts,
- apply threadlocker,
- then tighten them back to secure Part and the 2 Pillow Block.
Take part and align it with the holes on part as shown below
Take 7 - M4x16 flat bolts and tighten it into the 7 holes on part as shown below to secure it to part .
After the parts are aligned:
- remove each of the 7 – M4x16 flat bolts,
- apply threadlocker,
- then tighten them back to secure Part and part together.
Turn the current subassembly around such that part is facing downward toward the floor. You need to flush the 2 – Ball Joint Rod to flush against the 2 Pillow Block, then tighten the set screw on the Steel Set-Screw Collar to secure them in place accordingly.

Step 10: Install the Linkage Cranks and Cover
Install and align the ankle linkage cranks, attach the rear cover, and connect the XT30 cable connectors to actuator IDs 11 and 10.
Step 12: Assemble the Foot Pivot
Build the foot pivot by fastening parts 500_25A, 500_26B, 500_36A, 500_37C, and 500_39C to four pillow blocks with M4 bolts.
