Step 6: J5-J6-J7 Sub-Assembly
- Install the
FL6700ZZ
bearing into the sheet metal componentJ6_A
, and gently insertJ7_B
into the bearing, aligning it as shown in the figure.

- Repeat the procedure with
J6_B

- Attach
J5_A
to the rotor ofJ5
motor using 6M3x18
bolts

- Attach the
J6_B
component toJ5_A
using 3M3x8
bolts. Ensure thatJ6_B
is aligned towards the mechanical stop ofJ5_A

- Attach the component
J6_A
toJ5_A
using 3M3x8
bolts.

- Attach component
J6_D
to motorJ6
using fourM3x6
bolts. Ensure thatJ6_D
is aligned so its top and bottom line up with the two Power+CAN ports.

- Attach
J7_E
to the rotor ofJ6
using 6M3x6
bolts

- Carefully place the motor
J6
betweenJ6_A
andJ6_B
, and securely fasten it toJ6_A
using 4M3x6
bolts. As a check, the communication port should be in line withJ7_E

tip
When looking straight at J6_B
, J7_E
should be protruding to the right for the right arm, and to the left for the left arm.

- Attach part
J7_A
to theJ7
motor using threeM3x8
bolts. Make sure the orientation matches the image, with the top bolt aligned with the Power+CAN port.

- Using two
M3x8
bolts, mount partJ7_C
to the back of motorJ7
as shown. Check that it’s aligned correctly and runs parallel to the line between the two Power+CAN ports.

tip
While assembling the left arm, mount the part J7_C
on the opposite side.

- Insert bearings
MR106ZZ1
into the two holes of partJ7_D_right
.

tip
For assembling the left arm, use the part J7_D_left
.
- Carefully place the motor
J7
between theJ6_A
andJ6_B
sheet metal pieces, and attach the twoJ7_B
pieces toJ7_A
using 2M3x8
bolts on each side.

tip
J7_C
and J7_E
should face the same direction once this step is completed

- Attach the component
J7_D_right
to bothJ7_C
andJ7_E
using the step boltDBSY4-6-5
with 4 washersSWSPS12-6-0.5
between the step bolt andJ7_D
as well asJ7_D
andJ7_C
/J7_E
.

tip
While assembling the left arm, use the part J7_D_left
.

- Carefully insert
J6_C_right
part betweenJ6_A
andJ6_B
and secure them using 3M3x6
bolts

tip
When assembling the left arm, use component J6_C_left
.

info
That concludes the J5-J6-J7 Sub-Assembly
