Holding the Vehicle on an Incline With a
Slipping Clutch

A slipping clutch accumulates heat faster than it can
be dissipated, resulting in early clutch failures. Never
use the clutch as a hill holder.

Coasting With the Clutch Released
(Pedal Depressed) and the Transmission
in Gear

Coasting with the clutch released and the transmis-
sion in gear can cause high driven disc rpm through
multiplication of ratios from the final drive and trans-
mission.

WARNING

Do not coast with the clutch released (pedal de-
pressed) and the transmission in gear. High
driven-disc rpm could cause the clutch facing to
be thrown off the disc. Flying debris could cause
injury to persons in the cab.

Engaging the Clutch While Coasting

Engaging the clutch while coasting can result in tre-
mendous shock loads and possible damage to the
clutch, as well as to the entire drivetrain.

Reporting Erratic Clutch Operation
Promptly

Reporting erratic clutch operation as soon as pos-
sible will give maintenance personnel a chance to
inspect and lubricate the clutch components, make
necessary internal clutch and linkage adjustments,
etc.

Clutch free pedal is a decreased resistance felt at
the top of the clutch pedal stroke. See

Fig. 7.8

. With

the clutch pedal in this range, the clutch is fully en-
gaged and the only resistance to clutch pedal move-
ment is the force of the return spring. If clutch free
pedal is 3/4 inch (20 mm) or less, measured at the
pedal, have the clutch adjusted.

Free pedal should be included and commented on
daily in the driver’s report, since clutch free pedal is
the maintenance department’s guide to the condition
of the clutch and the release mechanism.

See Group 25 of the

Century Class Trucks Work-

shop Manual

for clutch adjustment procedures and

specifications.

CAUTION

Operating the vehicle with incorrect free pedal
could result in clutch damage.

Clutch brake squeeze is an increased resistance
(greater than the force of the clutch spring) felt as
the clutch pedal approaches the end of its stroke. If
the gears grind when shifting into first or reverse
gear with the clutch pedal fully depressed, the clutch
is out of adjustment or the clutch brake is worn and
needs to be replaced.

Clutch Adjustments

Clutches have an internal adjustment, and external
linkage adjustment. See Group 25 of the

Century

Class Trucks Workshop Manual

for clutch adjustment

procedures and specifications.
