Hydraulic Clutch Operating Members
The clutch system consists of the following components:
- A master cylinder with a remote reservoir and a hose assembly
- 2 switches
- An actuator cylinder connected to hydraulic tubing
- The pressure plate
- The clutch cover
- The diaphragm springs
- The clutch disc
- The torsional springs
With the depression of the clutch pedal, the clutch master cylinder becomes pressurized from the force of the push rod into the master cylinder. This forces hydraulic fluid into the tubing from the master cylinder to the actuator cylinder. The actuator cylinder then pushes the release bearing into the diaphragm spring to disengage the clutch. A hole in the cowl panel accommodates the master cylinder. A quick connect coupling helps route the hydraulic tubing. The actuator cylinder is inside the transmission and on the input bearing retainer. The hydraulic control system can be replaced without having to gain access to the clutch system internal components, simply engage the quick connect coupling mounted through the transmission housing. No adjustments to the clutch system are necessary. As the clutch wears, the fluid level in the master cylinder reservoir changes to compensates for clear wear. A new system will have fluid in the reservoir. An electrical switch on the push rod has two functions. One function is a clutch interlock, ensuring the engine does not start unless the clutch pedal is engaged, positioned to the floor. The second function is to cut off the cruise-control system, if equipped, when the clutch pedal is engaged. Some systems may have a clutch pedal hold down assist spring. Its purpose is to keep the clutch pedal depressed. This reduces driver fatigue during stop and go traffic.
