Clutch Controls
The clutch control system consists of these components:
- Clutch master cylinder and reservoir assembly
- Clutch slave cylinder
- Clutch pedal position switch
- Clutch pedal and support bracket
- Clutch master cylinder push rod and bushing
6.0L system shown, 5.4L and 6.8L similar.
The clutch control system actuates the clutch system. When the clutch pedal is depressed, it pushes the clutch master cylinder plunger which transmits hydraulic pressure to the clutch slave cylinder. The clutch slave cylinder engages and compresses the clutch pressure plate diaphragm spring, releasing the pressure on the clutch disc which, in turn, disengages the transmission from the engine.
The hydraulic clutch system adjusts automatically to compensate for clutch disc wear.
The clutch pedal starter interlock switch is attached to the clutch pedal. Depressing the clutch pedal manually closes the switch and allows engine cranking.
The clutch pedal deactivation switch deactivates the speed control system when the pedal is depressed.
