synchronizer will be bypassed.
z With the clutch pedal up, gently pull the shift lever toward the
reverse gear position. Gear clash can now be heard.
z Slowly depress the clutch pedal. Using the steering wheel
inner seam as a reference, note the measurement when the
gear clash stops or the shift lever slides into reverse gear.

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.
