CENTER THE TROLLEY NUT
NOTE:
It is critical to make sure that the trolley nut is placed in
the center of the drive screw.
1. Use a tape measure to make sure the trolley nut is located
center on the drive screw.
2. To reassemble the travel assembly over the trolley nut, it
might be helpful to move the trolley nut above or below the
cover screw hole standoffs, but it must be re-centered prior
to inserting the travel assembly back through the collar and
drive screw.
