FIGURE 4-3, ROTATIONAL MOTOR & DRIVE CHAIN
The hydraulic torque motor swings the boom left or right by means of a pair of sprockets & roller chain. The motor is
mounted to an adjustment plate located under the chain drive guards. The adjustment plate along with a pair of jack
screws allow for tightening the drive chain. Solenoid valve V-2 controls left/right movement.
