DIAGNOSIS AND TESTING
Manual Transmission and Clutch
Inspection and Verification
It is important to get an accurate description of the concern before any diagnosis can be carried out.
Ask questions as to whether it occurs when hot or cold, during shifting, driving at a particular speed or
in a particular gear. If possible, have the customer demonstrate the concern.
zWith the vehicle at a complete stop, shift through all the gears and evaluate the noise at
different engine rpm. Check for any noises in NEUTRAL at different engine rpm.

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.

1. Remove the transmission. For additional information, refer to Section 308 - 03A (T5OD) or
Section 308 - 03B (TR3650).
2. CAUTION: Loosen the bolts evenly to prevent clutch pressure plate damage.
NOTE: If the parts are to be reused, mark the clutch pressure plate and the flywheel.
Remove the bolts and remove the clutch pressure plate and the clutch disc.
Installation
NOTE: Clean the clutch pressure plate and flywheel with a commercial alcohol- based solvent so
surfaces are free from oil film.
Do not use cleaners with a petroleum base. Do not immerse the clutch pressure plate in the solvent.
1. Position the clutch disc on the flywheel. zUsing the special tool, align the clutch disc.

Installation
1. NOTE: Clean the clutch pressure plate and flywheel with a commercial alcohol- based solvent
so surfaces are free from oil film. Do not use cleaners with a petroleum base.
NOTE: Before installing the transmission, the ball stud, the clutch release lever and the input
shaft must be cleaned and lubricated with grease.
To install, reverse the removal procedure.
zUsing the special tool, align the clutch disc and pressure plate to the flywheel.
2. Tighten the pressure plate bolts in two stages. zStage 1: Tighten the bolts to 45 Nm (33 lb- ft).
z Stage 2: Tighten the bolts an additional 60 degrees. Klj . 3 ba

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
