3. If the height of the clutch pedal is outside the standard
value, loosen the setting nut to adjust the pedal height
to the standard value.
Caution
Do not push in the master cylinder push rod at this
time, otherwise the clutch will not operate properly.
4. After completing the adjustments, confirm that the clutch
pedal free play (measured at the face of the pedal pad)
and the distance between the clutch pedal (the face of
the pedal pad) and the clutch pedal stopper or toeboard
when the clutch is disengaged are within the standard
value ranges.
Standard value (C): 4 - 13 mm
Standard value (D):
114.3 mm or more
100 mm or more
5. If the clutch pedal free play and the distance between
the clutch pedal and the clutch pedal stopper or toeboard
when the clutch is disengaged do not agree with the
standard values, it is probably the result of either air in
the hydraulic system or a faulty master cylinder, clutch
cylinder or clutch. Bleed the air, or disassemble and inspect
the master cylinder, clutch cylinder or clutch.
