Check the clutch pedal shaft and bushing for wear.
Check the clutch pedal for bending or distortion.
Check the return spring for damage or deterioration.
Check the clutch pedal pad for damage or wear.
Measure the clutch pedal height (from the face of the pedal pad to the floorboard).
Standard value : (A) 160.7 mm (6.4 in.)
If the clutch pedal height is not within the standard value range, adjust as follows :
Turn and adjust the bolt, then secure by tightening the lock nut.
After the adjustment, tighten the bolt until it reaches the pedal stopper, and then tighten the lock nut.
Turn the push rod to agree with the standard value and then secure the push rod with the lock nut.
When adjusting the clutch pedal height, be careful not to push the push rod toward the master cylinder.
After completing the adjustments, check that the clutch pedal free play (measured at the face of the pedal pad) is within the standard value ranges.
Standard value : (B) 6-13 mm (0.24-0.52 in.)
If the clutch pedal free play do not meet with the standard values, it may be the result of either air in the hydraulic system or a faulty clutch master cylinder. Bleed the air or disassemble and inspect the master cylinder or clutch.
