F: ADJUSTMENT
1. CLUTCH PEDAL (2500 cc MODEL)
1) Turn cruise control clutch switch lock nuts until
clutch pedal full stroke length is within specifica-
tions.
CAUTION:
Do not attempt to turn clutch switch to adjust
clutch pedal full stroke length.
NOTE:
If lock nuts cannot adjust clutch pedal full stroke
length to specifications, turn master cylinder push
rod to adjust it.
Specified clutch pedal full stroke: A
130 Ð 135 mm (5.12 Ð 5.31 in)
Tightening torque (Clutch switch lock nut):
8
±2 N´m (0.8±0.2 kg-m, 5.8±1.4 ft-lb)

2) Turn master cylinder push rod so that clevis pin
moves to the left and then to the right. Clevis pin
must move without resistance while it is rattling.
Tightening torque (Push rod lock nut):
8
±2 N´m (0.8±0.2 kg-m, 5.8±1.4 ft-lb)
B4M1189A
3) Depress and release clutch pedal 2 to 3 times
to ensure that clutch pedal and release fork oper-
ate smoothly. If clutch pedal and release fork do
not operate smoothly, bleed air from clutch hydrau-
lic system.
4) Measure clutch pedal full stroke length again to
ensure that it is within specifications. If it is not,
repeat adjustment procedures again from the
beginning.
Specified clutch pedal full stroke:
130 Ð 135 mm (5.12 Ð 5.31 in)
5) Move clevis pin to the left and then to the right.
It should move without resistance while it is rattling.
If resistance is felt, repeat adjustment procedures
again from the beginning.
6) Push release lever until operating cylinder push
rod retracts. Ensure that clutch fluid level in reser-
voir tank increases. If clutch fluid level increases,
hydraulic clutch is properly adjusted; if fluid level
does not increase or push rod does not retract,
replace master cylinder with new one. 2-10 [W600].>
