PrecautionsNJCL0001+Recommended fluid is brake fluid ªDOT 4º. Refer to
MA-16, ªFluid and Lubricantsº.
+Never reuse drained brake fluid.
+Be careful not to splash brake fluid on painted areas.
+When removing and installing clutch piping, use Tool.
+Use new brake fluid to clean or wash all parts of master
cylinder and operating cylinder.
+Never use mineral oils such as gasoline or kerosene. It will
ruin the rubber parts of the hydraulic system.
WARNING:
After cleaning clutch disc, wipe it with a dust collector. Do not
use compressed air.
PRECAUTIONS
Precautions
CL-2

CLUTCH PEDAL ADJUSTMENTNJCL0006S04Pedal StrokeNJCL0006S04011. Loosen the pedal stopper bolt completely (so there is no con-
tact between pedal and stopper bolt).
2. Adjust pedal stroke to the specified value with the master cyl-
inder push rod.
3. Adjust the pedal stopper bolt until it is just in contact with the
pedal, then tighten the lock nut.
4. Once stroke is set to specification, adjust clutch pedal free
play.
Pedal stroke ªSº.
Refer to ªSDSº, CL-24.
Pedal Free PlayNJCL0006S04021. Adjust pedal free play to the specified value with the master
cylinder push rod.
2. Tighten lock nut of the master cylinder push rod.
+Push on the clutch pedal until resistance is felt, and check the
distance the pedal moves.
Pedal free play ªAº.
Refer to ªSDSº, CL-24.

AIR BLEEDING PROCEDURENJCL0006S021. Bleed air from clutch operating cylinder according to the fol-
lowing procedure.
+Carefully monitor fluid level at master cylinder during
bleeding operation.
a. Top up reservoir with recommended brake fluid.
b. Connect a transparent vinyl tube to air bleeder valve.
c. Slowly depress the clutch pedal to its full stroke and release it
completely. Repeat this operation several times at 2 to 3 sec-
onds intervals.
d. Open the air bleeder with the clutch pedal fully depressed.
e. Close the air bleeder.
f. Release the clutch pedal and wait at least 5 seconds.
g. Repeat steps c through f mentioned above, then air bubbles
will no longer appear at the damper in the brake fluid.
Air bleeder valve tightening torque:
: 5.9 - 9.8 N´m (0.6 - 1.0 kg-m, 52 - 86 in-lb)

RemovalNJCL00081. Drain brake fluid.
CAUTION:
Be careful not to splash brake fluid on painted areas; it may
cause paint damage. If brake fluid is splashed on painted
areas, wash it away with water immediately.
2. Remove clutch tube using a flare nut wrench.
3. Remove snap pin between clutch pedal and push rod, and
remove clevis pin.
4. Unscrew master cylinder assembly mounting nuts and remove
master cylinder assembly from vehicle.
InstallationNJCL00091. Connect clutch tube to master cylinder assembly, and hand-
tighten flare nut.
2. Install master cylinder assembly to vehicle, and tighten mount-
ing nuts to the specified torque.
: 11 - 14 N´m (1.1 - 1.5 kg-m,8-10ft-lb)
3. Tighten clutch tube flare nut using a flare nut torque wrench.
: 15 - 18 N´m (1.5 - 1.8 kg-m, 11 - 13 ft-lb)
4. After installing clevis pin, install snap pin to connect clutch
pedal to push rod.
5. After finishing the operation, bleed air from clutch piping con-
nector and operating cylinder. (Refer to ªAir Bleeding
Procedureº, CL-10.)
SCL725
DisassemblyNJCL00101. Loosen push rod lock nut A to remove clevis and lock nut A.
2. Remove dust cover.
3. Remove stopper ring and stopper, and remove push rod from
cylinder body. During removal, keep push rod depressed, to
prevent piston inside master cylinder from popping out.
4. Remove piston assembly from cylinder body.
InspectionNJCL0011Check the following items, and replace if necessary.
+Rubbing surface of cylinder and piston, for uneven wear, rust
or damage
+Piston with piston cup, for wear or damage
+Return spring, for wear or damage
+Dust cover, for cracks, deformation or damage
+Reservoir, for deformation or damage

CAUTION:
Be careful not to splash brake fluid on painted areas; it may
cause paint damage. If brake fluid is splashed on painted
areas, wash it away with water immediately.
2. Remove union bolt and clutch hose from operating cylinder.
3. Remove operating cylinder mounting bolts, and remove cylin-
der from vehicle.
DisassemblyNJCL0021Remove dust cover, and remove piston assembly from cylinder
body.
InspectionNJCL0022Inspect for following, and replace parts if necessary.
+Damage, foreign material, wear, rust, and pinholes on the cyl-
inder inner surface, piston, and sliding part of piston cup
+Weak spring
+Crack and deformation of dust cover

5. Remove clutch hose and clutch tube.
SCL730
InstallationNJCL00431. When installing clutch hose to bracket, face lock plate in the
correct direction as shown to secure clutch hose.
CAUTION:
Install clutch hose without twisting or bending it.
2. Tighten flare nut to the specified torque, using a flare nut
wrench.
: 15 - 18 N´m (1.5 - 1.8 kg-m, 11 - 13 ft-lb)
CAUTION:
Be careful not to damage flare nut and clutch tube.
3. Install clutch hose to operating cylinder, and tighten mounting
bolts to the specified torque.
