Color Change Motor Belt Tension
The color change belt tension should cause the color change cam to rotate with
minimum backlash. The belt should be tensioned with some amount of slack so it is
not so tight that it wears the color change shaft and bushings needlessly.
Adjust the color change belt tension by loosening the color change motor
mounting screws and moving the motor to make the belt more or less taut. Set the
belt tension to 6-7 pounds using the Gates 5M Tensiometer. When tightening the
belt tension, use hand pressure only on the motor. No additional force is needed.
Replace all the covers removed to perform this service.

If replacing the color change cam and associated hardware, refer to the following
procedure to allow the new assembly to rotate freely within the bracket.
