CLUTCH PEDAL ADJUSTMENT
Adjustment Procedure
1. Determine the clutch pedal play. Depress the clutch
pedal lightly with your hand and measure the dis-
tance when you feel resistance.
2. Adjust the clutch pedal play. Loosen the locknut
and turn the pushrod. Clutch pedal play should
measure 6 to 12 mm (0.2 to 0.5 inch). Tighten the
locknut after adjustment.
3. Measure the clutch pedal travel. Press the clutch
pedal all the way to the floor. Measure from the
starting position to the ending position.
4. Adjust the clutch pedal travel. Loosen the locknut
and turn the bolt. Clutch pedal travel should mea-
sure 130 to 140 mm (5.1 to 5.5 inches). Tighten the
locknut after adjustment.

CLUTCH RELEASE POINT
ADJUSTMENT
Adjustment Procedure
1. Apply the parking brake.
2. Run the engine at idle speed.
3. While you move the shift lever into the reverse
position, depress the clutch pedal slowly and mea-
sure the distance between the point when gear
noise is not heard and the point the clutch pedal is
completely depressed. The distance should be 30
to 40 mm (1.2 to 1.6 inches).
4. If the distance is not within the specified value,
check the following:
S Clutch pedal height
S Clutch pedal play
S Air in the system
S Clutch cover and disc pressure plate
AIR BLEEDING
Bleed the hydraulic system to remove the air which en-
tered when the pipes were disconnected for repairs. The
clutch/brake fluid in the clutch/brake reservoir must be
maintained at the MIN level or higher during air bleeding.
1. Attach a vinyl hose to the bleeder plug. Place the
other end of the vinyl tube in a glass container half–
filled with brake fluid.
2. Slowly pump the clutch pedal several times.
3. While you press the clutch pedal, loosen the bleed-
er screw until the fluid starts to run out. Close the
bleeder screw.
4. Repeat Step 3 until there are no air bubbles in the
fluid.
5. Fill the reservoir with brake fluid up to the proper
level.
PRESSURE PLATE AND CLUTCH
DISC
Removal Procedure
1. Disconnect the negative battery cable.
2. Remove the transaxle from the vehicle. Refer to
Section 5B, Five–Speed Manual Transaxle.
3. Remove the pressure plate bolts and the pressure
plate.
Important : Support the pressure plate when you remove
the last bolt.

Inspection Procedure Clutch Disc
1. Visual Inspection
S Inspect the worn or oily contamination on the
clutch surface.
S Inspect the damaged or weakened torsion
spring.
S Inspect the a warped or bent clutch disc. After
inspection, replace new clutch disc, if necessary.
2. Clutch Disc Inspection
S Measure the rivet head depth from the clutch
disc surface.
S Replace the clutch disc if the measured value is
below the limit.
S Rivet Head Depth (Limit) : 0.3 mm (0.012 in)
Inspection Procedure Pressure Plate
1. Check for a worn diaphragm spring finger.
2. Check for a worn or cracked pressure plate sur-
face.
3. Check for the polluted face by the oil. After inspec-
tion, replace the pressure plate if necessary.
