CLUTCH PEDAL INSPECTION AND
ADJUSTMENT
1. Turn up the carpet, etc. under the clutch pedal.
2. Measure the clutch pedal height.
Standard value (A): 163.5 – 166.5 mm
3. If the height of the clutch pedal is outside the standard
value, loosen the locking nut and adjust the pedal height
to the standard value using the adjusting bolt or push
rod.
