Using the Clutch Brake
The clutch brake is applied by depressing the clutch
pedal past the fully released clutch position, almost
to the floor plate. The last part of the clutch pedal
travel will compress the clutch brake plates together,
stopping the transmission input shaft. The purpose of
the clutch brake is to stop the transmission gears
from rotating in order to quickly engage a transmis-
sion gear after idling in neutral.
CAUTION
Never apply the clutch brake when the vehicle is
moving. If the clutch brake is applied when the
vehicle is moving, the clutch brake will try to
stop or decelerate the vehicle, causing rapid
wear of the clutch brake friction discs. Consider-
able heat will be generated, causing damage to
the release bearings and the transmission front
bearings.
Holding the Vehicle on an Incline
Always use the vehicle service brakes to prevent the
vehicle from rolling backwards while stopped on a
hill. Slipping the clutch on a hill to maintain the ve-
hicle position will quickly damage the clutch assem-
bly.
Coasting
Coasting with the clutch pedal depressed and the
transmission in a low gear can cause high driven
disc speed. The clutch speed can be much higher
under these conditions than when the engine is driv-
ing the clutch. This condition creates a hazardous
situation due to the lack of vehicle control and due to
the high clutch disc speed. Engaging the clutch
under these conditions can cause component dam-
age because of the shock loads to the clutch and
drivetrain.
WARNING
Always shift into the gear that is correct for the
traveling speed of the vehicle and engage the
clutch. Coasting with the clutch disengaged can
prevent engagement of the correct transmission
gear which can cause loss of vehicle control,
possibly resulting in personal injury or property
damage.
High clutch disc speeds while coasting can also
cause the clutch facing to be thrown off the disc.
Flying debris from the clutch can cause injury to
persons in the cab.
Clutch Maintenance
Clutch Adjustment
Eaton Fuller Solo clutches are adjustment-free. As
the clutch wears, its wear-adjusting technology moni-
tors clutch components and makes any necessary
adjustments. The wear adjusting technology comes
from two sliding cams, which rotate to maintain the
proper adjustment. Atop the upper cam, a wear indi-
cating tab mirrors the cam’s movement, letting you
know when it’s time to replace the clutch.
CAUTION
Operating the vehicle with incorrect free pedal
could result in clutch damage.
Hydraulic Clutch Fluid Reservoir
Checking
Make sure that the clutch fluid reservoir is full. See
Fig. 14.4
. The reservoir is full when the fluid level is
up to the "max" mark. The fluid level must always be
above the "min" mark. Use only heavy-duty brake
fluid, DOT 4, in the clutch hydraulic system.
