How to Use the Hydraulic Clutch
CAUTION
Be careful not to apply the clutch
brake
while the vehicle is moving. The
purpose of the clutch brake is to stop
the transmission so that you can shift
into a starting gear without grinding
gears. Applying the clutch brake when
the vehicle is moving causes a braking
effect on the drivetrain and shortens
the service life of the clutch brake.
CAUTION
DO NOT push the clutch pedal com-
pletely
to the floor when shifting while
the vehicle is in motion. using the
clutch brake while shifting a vehicle in
motion will damage the clutch brake. A
non functioning clutch brake will make
shifting very difficult when the vehicle
is stationary.
1. Depress the clutch pedal past the
first 1/2 in. (13 mm) for
approximately 5 1/2 in. (139.7 mm)
of total pedal travel.
2. Depress the clutch pedal another
1/2 in. (13 mm) to engage the
clutch brake.
The clutch brake is used for stopping
transmission gears, allowing you to easily
shift into first gear or reverse without
grinding gears. The clutch brake is not
necessary when shifting into other gears
while in motion.
If the clutch pedal is pressed completely to
the floor and the transmission is not
shifting, then it is time to have the clutch
adjusted or serviced.
If the transmission has a butt-tooth
condition and you cannot engage a gear
,
gradually release the clutch. Then the drive
gear can roll enough to allow the teeth to
line up properly and complete the shift.
The clutch is not a footrest. Do not drive
with your foot resting on the clutch pedal. It
will allow your clutch to slip, causing
excessive heat and wear, damage could
result.
When you must idle your engine for any
period of time, shift your transmission to
neutral and disengage the clutch (take your
foot OFF of the pedal). This helps prevent
unnecessary wear to your clutch release
bearing, and it is less tiring for you, too.
• Always use the clutch when
making upshifts or downshifts.
• Never coast with the transmission
in neutral and the clutch
disengaged.
• To provide smooth gear
engagements while shifting, use
proper coordination between shift
lever and clutch.
How to Shift Using Double Clutch
Method
Double clutching is easier on the
transmission and on the engine, helping
match your vehicle's engine speed with
driveline speed to achieve clash-free shifts.
The manual transmission in your vehicle is
not equipped with gear synchronizers.
Whether you are upshifting or
downshifting, it is best to double clutch.
To double clutch:
1. Push the clutch pedal down to
disengage the clutch.
2. Move the gear shift lever to neutral.
3. Release the pedal to engage the
clutch. This lets you control the rpm
of the transmission mainshaft
gears, allowing you to match the
rpm of the mainshaft gears to those
of the output shaft.
