Page 2 of 17 The clutch control system engages and disengages the clutch. The clutch control system disengages the clutch when the clutch pedal is depressed and engages the clutch when the clutch pedal is released. Clutch pedal motion is transmitted by the clutch release lever cable to the clutch release lever. The clutch release hub and bearing engages the clutch pressure plate diaphragm spring, releasing the pressure on the clutch disc which in turn disengages the transmission from the engine. The clutch adjusts automatically to compensate for clutch disc wear. The clutch linkage is selfadjusting. The clutch pedal position (CPP) switch prevents the starter motor from engaging unless the clutch pedal is depressed all the way to the floor. The switch plunger is contacted by the clutch pedal and extends as the clutch pedal is pressed. The clutch pedal position switch is electrically connected in line with the ignition switch and the starter motor relay coil. The CPP also turns off the speed control when the clutch pedal is depressed. DIAGNOSIS AND TESTING > CLUTCH CONTROLS Refer to MANUAL TRANSMISSION, CLUTCH & TRANSFER CASE - GENERAL INFORMATION.
