3-66.3. SYNCHRONIZING MOTOR - MAINTENANCE INSTRUCTIONS.

a. The hydraulic governor is equipped with a reversible electric synchronizing motor mounted on the governor cover. This motor

permits close adjustment of the engine speed from a remote control point. This feature is especially valuable when synchronizing two

generators from a central control panel.

b. The motor is connected to the source of electrical supply through a two-way switch located on the Main Switchboard. The

friction drive components are assembled to the drive shaft of the synchronizing motor and extend down through the governor cover. The

speed adjusting screw of the friction drive is threaded into the governor cover and bears directly on the speed adjust lever.
