On-Vehicle Inspection and AdjustmentECS001WB
1. Make sure that clevis pin floats freely in bore of clutch pedal. It
should not be bound by clevis or clutch pedal.
a. If clevis pin is not free, make sure that pedal stopper bolt or
ASCD clutch switch is not applying pressure to clutch pedal
causing clevis pin to bind. To adjust, loosen lock nut and turn
pedal stopper bolt or ASCD clutch switch.
b. Tighten lock not.
c. Make sure that clevis pin floats in bore of clutch pedal. It should
not be bound by clutch pedal.
d. If clevis pin is still not free, remove clevis pin and check for
deformation or damage. Replace clevis pin if necessary. Leave
clevis pin removed for step 2.
2. Check clutch pedal stroke for free range of movement.
a. With clevis pin removed, manually move clutch pedal up and
down to determine if it moves freely.
b. If any sticking is found, replace related parts (clutch pedal
bracket, assist spring, bushing etc.). Reassemble clutch pedal
and again make sure that clevis pin floats freely in bore of clutch
pedal.
3. Check clutch hydraulic and system components (clutch master
cylinder, clutch operating cylinder, clutch withdrawal lever, clutch
release bearing, etc.) for sticking or binding.
a. If any sticking or binding is found, repair or replace related parts as necessary.
b. If hydraulic system repair was necessary, bleed the clutch hydraulic system. Refer to CL-8, "
Air Bleeding
Procedure" .
NOTE:
Do not use a vacuum assist or any other type of power bleeder on this system. Use of a vacuum assist or
power bleeder will not purge all the air from the system.

Air Bleeding ProcedureECS008B9
NOTE:
Do not use a vacuum assist or any other type of power bleeder on this system. Use of a vacuum assist or
power bleeder will not purge all the air from the system.
CAUTION:
Monitor clutch fluid level in reservoir tank to make sure it
does not empty.
Keep painted surface on the body or other parts free of
clutch fluid. If it spills, wipe up immediately and wash the
affected area with water.
Bleed the air of operating cylinder.
1. Fill master cylinder reservoir tank with new clutch fluid.
2. Connect a transparent vinyl hose to air bleeder valve.
3. Depress clutch pedal slowly and fully several times at an interval
of 2 to 3 seconds and hold it.
4. With clutch pedal depressed, open air bleeder valve to release
air.
5. Close air bleeder valve.
6. Release clutch pedal and wait for 5 seconds.
7. Repeat steps 3 to 6 until no bubbles can be observed in clutch
fluid.
8. Tighten air bleeder valve to the specified torque. Refer to CL-12,
"Components" .
