(1) Mount the U1 pulley and the motor plate to the
new Joint #4 motor.
Pull the pulley to the motor side with 50N force to
pressurize the bearing while securing the pulley.
Tighten one of the set screws on the flat face of
the motor shaft until the screw just touches the
surface.
Insert a bushing into the other set screw hole to
prevent damage to the motor shaft. Then, tighten
both set screws.

(3) Place the U belt around the U1 pulley and the U2
pulley so that the gear grooves of the belt are fit
into those of the pulleys completely.
(4) Loosely secure the Joint #4 motor unit to Arm #2.
Loosely secure the Joint #4 motor unit to Arm #2
so that the motor unit can be moved 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.

(5) Apply the proper tension to the U belt, and
then secure the Joint #4 motor unit.
To do so, pass a suitable cord or string
around the Joint #4 motor unit near its
mounting plate. Then, pull the cord using a
force gauge or similar tool to apply the
specified tension shown in the figure on the
right.
Make sure that the brake cables do not touch
the pulley.
