Take part and put it on top of the legs of the Pillow Block. Make sure the 4 holes on the surface of the circumference of part aligned with the Pillow Block leg.
Take 4 of and lightly tighten them into the 4 holes on the circumference of part to align it to the 2 Pillow Blocks.
After the parts are aligned:
- remove 4 of one at a time,
- apply threadlocker,
- then tighten them back to secure Part and the 2 Pillow Blocks.
Now flip the current assembly upside down so that the part is facing downward toward the floor. Put the assembly to one side.
