GENERAL PROCEDURES
Disc Check
WARNING: Dust and dirt present on wheel brake and clutch assemblies may contain
asbestos fibers that are hazardous to health when made airborne by cleaning with compressed
air or by dry brushing. Failure to follow these instructions may result in personal injury.
WARNING: Wheel brake assemblies and clutch facings should be cleaned using a vacuum
cleaner recommended for use with asbestos fibers such as the brake automobile brake drum
system with vacuum. Dust and dirt from the vacuum should be disposed of in a manner that
prevents dust exposure such as sealed bags. The bag must be labeled according to OSHA
instructions and the trash hauler notified as to the bag's contents. Failure to follow these
instructions may result in personal injury.
WARNING: If a vacuum suitable for asbestos is not available, cleaning should be done
wet. If dust generation is still possible, technicians should wear government- approved toxic
dust purifying respirators. Failure to follow these instructions may result in personal injury.
WARNING: Grinding or sanding on the brake linings, pads, rotors, drums or clutch
facings should be done only while using correct exhaust- ventilated equipment. Failure to
follow these instructions may result in personal injury.
WARNING: OSHA requires areas where asbestos dust generation is possible to be
isolated and posted with warning signs. Only technicians concerned with carrying out brake or
clutch service should be present in the area. Failure to follow these instructions may result in
personal injury.
1. Check the clutch disc lining surface for hardening or the presence of oil.
2. Check for a worn clutch disc lining. Measure the minimum allowable depth to the rivet heads with a slide caliper.

DESCRIPTION AND OPERATION
Clutch
The primary function of the clutch is to couple and uncouple engine power to the transmission upon
driver command. For additional information, refer to
Section 308 - 02 .
z The clutch is a single plate, dry friction clutch disc. The clutch disc has a splined hub (with
integral torsional dampening springs) which attaches the clutch disc to the input shaft.
z Engine output is coupled to the input shaft by the friction existing between the clutch disc
facings and the flywheel/clutch pressure plate assembly. The extent of this friction is directly
related to the composition of the facing material and the magnitude of the clamping force
exerted by the clutch pressure plate. These factors limit the amount of torque that can be
transmitted without slippage.
z The clamping force is obtained from a diaphragm spring contained within the clutch pressure
plate assembly. This force is developed during the attachment of the clutch pressure plate to
the flywheel.
z The clutch system is disengaged when the clutch pedal is depressed and engaged when the
clutch pedal is released. This displacement removes the spring load from the clutch pressure
plate and eliminates the coupling friction between the engine and the transmission.
z When the clutch pedal is depressed, a cable connected to the clutch release lever, hub and
bearing actuates the clutch pressure plate diaphragm spring, releasing pressure on the clutch
disc. This eliminates the engagement between the transmission and the engine.

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 self-
adjusting.
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. 4 7L583 Clutch pedal quadrant and pawl assembly Klj . 2 ba
