E: INSPECTION

1. CLUTCH PEDAL

Move the clutch pedal in the lateral direction with a force of approximately 10 N (1 kgf, 2 lbf) to check that the clutch pedal deflection is within the service limit.

CAUTION: If the deflection exceeds the service limit, replace with a new clutch pedal assembly.

Deflection of the clutch pedal: Service limit 4.0 mm (0.157 in) or less

F: ADJUSTMENT

1) If the full stroke of the clutch pedal is not within the specified value, loosen the lock nuts of the clutch switch and adjust the full stroke of the clutch pedal with the clutch switch.

CAUTION: When adjusting the full stroke of clutch pedal, do not turn the clutch switch.

Clutch pedal full stroke A:
130 - 135 mm (5.12 - 5.31 in) (non-turbo model)
135 - 140 mm (5.31 - 5.51 in) (turbo model)

Tightening torque: T: 8 N*m (0.8 kgf-m, 5.9 ft-lb)

2) Depress and release the clutch pedal two or three times to ensure that the clutch pedal and release lever operate smoothly. If the clutch pedal and release lever do not operate smoothly, bleed air from the clutch hydraulic system. <Ref. to CL- 25, Clutch Fluid Air Bleeding.>

3) Measure the clutch pedal full stroke length again to ensure that it is within specifications. If it is not within specifications, repeat adjustment procedures again from the beginning.

Clutch pedal full stroke:
130 - 135 mm (5.12 - 5.31 in) (non-turbo model)
135 - 140 mm (5.31 - 5.51 in) (turbo model)

4) Push the release lever until the operating cylinder push rod retracts. Make sure that the clutch fluid level in the reservoir tank increases. If the clutch fluid level increases, the hydraulic clutch is properly adjusted; If the clutch fluid level does not increase or the push rod does not retract, replace the master cylinder with a new part. <Ref. to CL-20, Master Cylinder.>

6) If the clutch fluid level increases, hydraulic clutch play is correct.

7) If the clutch fluid level does not increase or push rod does not retract, readjust the clutch pedal.

8) Check the clutch fluid level using the scale on the outside of the reservoir tank. If the clutch fluid level is below "MIN", fill the clutch fluid up to "MAX" level.

Recommended clutch fluid: New FMVSS No. 116 DOT3
