CLUTCH PEDAL
4. Adjust ASCD clutch switch (1), if equipped. Position so that
clearance between clutch pedal (2) and thread end of ASCD
clutch switch (1), with clutch pedal fully released, is within speci-
fication (A).
5. Check the clutch hydraulic system components (clutch master cylinder, clutch operating cylinder, clutch
withdrawal lever and clutch release bearing) for sticking or binding.
a. If any sticking or binding is noted, repair or replace the related parts as necessary.
b. If any hydraulic system repair was necessary, bleed the clutch hydraulic system. Refer to CL-8, "
Air
Bleeding Procedure".
NOTE:
Do not use a vacuum assist or any other type of power bleeder on this system. Use of a vacuum assist or
power bleeder will not purge all of the air from the system.

CLUTCH FLUID
Air Bleeding ProcedureINFOID:0000000001703119
CAUTION:
Do not spill clutch fluid onto painted surfaces. If it spills, wipe up immediately and wash the affected
area with water.
NOTE:
• Do not use a vacuum assist or any other type of power bleeder on this system. Use of a vacuum assist or
power bleeder will not purge all the air from the system.
• Carefully monitor fluid level in reservoir tank during bleeding operation.
1. Fill master cylinder reservoir tank with new clutch fluid.
2. Connect a transparent vinyl tube and container to the bleeding
connector (1) on the CSC.
3. Depress and release the clutch pedal slowly and fully 15 times
at an interval of two to three seconds and release the clutch
pedal.
4. Bleed the air from the clutch system according to the following:
1. Push in the lock pin (1) of the bleeding connector (2), and
hold it in.
CAUTION:
Hold the lock pin in to prevent the bleeding connector
from separating when fluid pressure is applied.
2. Slide the clutch tube (1) away from the bleeding connector
to the specified distance (A) to allow air to bleed from the
clutch system.
3. Depress the clutch pedal and hold it down.
CAUTION:
Hold the clutch pedal down to prevent air from getting
back into the clutch system.
4. Return the clutch tube (1) and lock pin (2) to their original
positions.
5. Release the clutch pedal and wait for 5 seconds.
6. Repeat steps 3 to 6 until no bubbles are observed in the clutch fluid.

CAUTION:
• If transaxle assembly is removed from the vehicle, always replace CSC (Concentric slave cylinder).
Return CSC insert to original position to remove transaxle assembly. Dust on clutch disc sliding
parts may damage CSC seal and may cause clutch fluid leakage.
• Keep painted surface of the body and other parts free of clutch fluid. If it spills, wipe up immediately
and wash the affected area with water.
REMOVAL
1. Remove transaxle assembly. Refer to MT-16, "Removal and Installation".
2. Remove CSC bolts and the CSC from clutch housing.
INSTALLATION
1. Install CSC to clutch housing and then tighten bolts to specification. Refer to MT-17, "Disassembly and
Assembly".
CAUTION:
• Do not reuse CSC.
• Do not insert and operate CSC because piston and stopper of CSC components may fall off.
2. Install transaxle assembly. Refer to MT-16, "
Removal and Installation".
3. Bleed the air from the clutch hydraulic system. Refer to CL-8, "
