CLUTCH PEDAL INSPECTION AND ADJUSTMENTMZlFAAP
1.Measure the clutch pedal height (from the face of the pedal
pad to the firewall).
Standard value: 177
- 182 mm (6.97 - 7.17 in.)
If the clutch pedal height is not within the standard value
range, adjust as follows:
For vehicles without auto-cruise control system, turn and
adjust the bolt so that the pedal height is the standard
value, and then secure by tightening the lock nut to the
specified torque.
Vehicles with auto-cruise control system, disconnect the
clutch switch connector and turn the switch for standard
clutch pedal height. Tighten the lock nut to the specified
torque.
Specified torque: 13 Nm (9
ft.lbs.)
NOTEWhen the pedal height is lower than the standard value,
loosen the bolt or clutch switch, and then turn the push rod
to make the adjustment. After making the adjustment,
tighten the bolt or clutch switch to reach the pedal stopper,
and then lock with the lock nut.
2. Measure the clutch pedal stroke.
Standard value: 160 mm (6.29 in.) or more
If the clutch pedal stroke deviates from the standard value,
turn the push rod to adjust the stroke.
3. Return the clutch pedal gradually from its full-stroke
position to measure amount of the return made by the
pedal
u,ntil the interlock switch makes an operating sound.
Standard value: 10
- 15 mm (.394 - .591 in.)
If the amount of pedal return deviates from the standard
value, adjust it by loosening the lock nut and turning the
interlock switch.
