The mechanism is removed by unscrewing the two slotted bolts on each side of the gyralight. These slotted bolts screw into threaded assemblies attached to each side of the gyralight housing.

Photos of the motor and connecting components. The fixed ball joint is located in the middle of the unit. The motor is attached to the light platform on the top end through a heavy duty gearbox, a set of pulleys and a belt, an eccentric and a connecting slide. The slide moves in a reciprocating pattern when the motor is activated. This in turn causes the right hand side of the frame to reciprocate thus creating a circular or oval movement of the light beams.
