Loosely secure the units to Arm #2 so that the motor unit can be moved by hand, and
it will not tilt when pulled. If the units are secured too loose or too tight, the belt
will not have the proper tension.
(4) Apply the proper tension to the U2 belt, and
then secure the Joint #4 intermediate shaft unit.
To do so, pass a suitable cord or string around
the Joint #4 intermediate shaft 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.
