Instructions
Take Sub Assembly A and lay it flat on the surface such that the L-shape part is facing upward toward the ceiling.
Take part and oriented it such that the solid knee portion is facing upward toward the ceiling. Slot Sub Assembly A into part such that the two motor holes are aligned with the knee portion first to help us estimate how the part will fit together.
Turn the leg toward the right so we can see the part of Sub Assembly A with the bearing on the motor facing upward toward the ceiling.
Take part and fit it on to the groove on part , such that the protrusion fits into the bearing and then all the holes on part align with the threaded insert on part .
Take 9 – M3x10 flat bolts and lightly tighten into all the holes on part to align it with part . Once it is aligned, tighten the bolts and secure the two parts together.
Flip the Sub Assembly A 180 degree on the other side such that part is now facing downward toward the surface. You should be able to see the motor shaft facing toward the ceiling.
Take 2 – M3x18 socket bolts and lightly tighten into the threaded holes on the motor shaft. Make sure that the bolts are on the opposite side of each other, use those bolts as the leverage to turn the motor shaft so that the bolts is on a straight line with the rest of part . This makes it easier to align with part later on. Remove the 2 – M3x18 socket bolts.
Align part with the motor such that the 6 holes nearer to the center of part aligned with the threaded holes on the motor.
Take 6 – M3x18 socket bolts and lightly tighten into the 6 holes near to the center of part to align the part with the motor. During this time also make sure that part is aligned with the groove on part .
Once the parts are aligned, remove each of the M3x18 sockets, apply the threadlocker onto them and tighten them back into the holes to secure part to the motor.
Take 9 – M3x10 flat bolts and lightly tighten into all the holes on part to align it with part . Once it is aligned, tighten the bolts and secure the two parts together.
