An elecro-hydraulic reducer was designed to power the sculpture. An electric motor spins at 1000 rpm at the beginning of the gear chain reduction. After eleven sets of reductions though the Ford V8 timing chains, the output spins at one-half of a revolution per minute. The eccentric shaft output works a hydraulic pump back-and-forth to suck oil out of the reservoir and supply hydraulic pressure to the ram cylinders. The combination of mechanical and hydraulic reduction allows each car to move at about 0.005 inches per minute 24-hours a day for the duration of the show.
