effort, gear clash and grinding or transmis-
sion blockout. When any of these problems
occur, a careful analysis of these difficulties
should be accomplished and the basic checks
and adjustments performed before removing
the clutch or transmission for repairs. Run the
engine at a normal idle with transmission in
neutral and clutch engaged. Disengage the
clutch, wait about 10 seconds and shift the
transmission to reverse. No grinding noise
should be heard. A grinding noise indicates
incorrect clutch travel, lost motion, clutch
misalignment, or internal problems such as
failed dampers, facings, cushion springs, dia-
phragm spring fingers, pressure plate drive
straps, pivot rings, etc.
CAUTION: When servicing clutch parts,
do not create dust by grinding or sanding
clutch disc or by cleaning parts with a dry
brush or with compressed air. (A water
dampened cloth—NOT SOAKED—should
be used) The clutch disc contains asbestos
fibers which can become airborne if dust is
created during servicing. Breathing dust
containing asbestos fibers may cause seri-
ous bodily harm.
