(3) Set the J2 belt around the pulley of the Joint #2
motor unit and secure the unit loosely.
Make sure the gear grooves of the belt are fit into
those of the pulleys completely.
Set the motor cable facing toward the other side
to J2 axis.
When securing the unit, make sure that the motor
unit can move by hand, and it will not tilt when
pulled. If the unit is secured too loose or too
tight, the belt will not have the proper tension.
