PRECAUTIONS
PRECAUTIONS PFP:00001
Precautions ECS0068J
q Recommended fluid is brake fluid "DOT 3".
q Never reuse drained brake fluid.
q Be careful not to splash brake fluid on painted areas.
q When removing and installing clutch piping, use Tool.
q Use new brake fluid to clean or wash all parts of master cyl-
inder and operating cylinder.
q Never use mineral oils such as gasoline or kerosene. It will
ruin the rubber parts of the hydraulic system.
WARNING:
After cleaning clutch disc, wipe it with a dust collector. Do not SBR686C
use compressed air.

CLUTCH PEDAL
Removal and Installation ECS0068P
Refer to CL-5, "Components" .
INSPECTION AFTER REMOVAL
q Inspect for clutch bending, damage and welding cracks. Replace if necessary.
q Make sure that the assist spring and return spring have not lost their spring. Replace if necessary.
On-vehicle Inspection and Adjustment ECS0068O
1. Check to see if the clutch pedal clevis pin floats freely in the bore
of the clutch pedal. It should not be bound by the clevis or clutch
pedal.
a. If the pin is not free, check that the ASCD switch or pedal stop-
per bolt is not applying pressure to the clutch pedal causing the
pin to bind. To adjust, loosen the ASCD switch or pedal stopper
bolt lock nut and turn the ASCD switch or pedal stopper bolt.
b. Tighten the lock nut.
c. Verify that the clutch pedal clevis pin floats freely in the bore of
the clutch pedal. It should not be bound by the clevis or clutch
pedal.
d. If the pin is still not free, remove the pin and check for deforma-
tion or damage. Replace the pin if necessary. Leave the pin
removed for step 2.
2. Check the clutch pedal stroke for free range of movement.
a. With the clutch pedal clevis pin removed, manually move the
pedal up and down to determine if it moves freely.
b. If any sticking is noted, replace the related parts (clutch pedal,
pedal bracket, assist spring, bushing, etc.). Reassemble the
pedal and re-verify that the clevis pin floats freely in the bore of
the pedal.
WCIA0146E
3. Adjust the clearance "C" while fully depressing the clutch pedal
(with the clutch interlock switch) as shown.
Clearance "C" : 0.1 - 1.0 mm (0.004 - 0.039 in)
4. Check the clutch hydraulic 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 noted, repair or replace the related
parts as necessary.
b. If the hydraulic system was necessary, bleed the clutch hydrau-
lic system. Refer to CL-7, "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 of the air from the system.

Air Bleeding Procedure ECS0068Q
NOTE:
Do not use a vacuum assist or any other type of power bleeder on this system. Use of a vacuum assist or B
power bleeder will not purge all the air from the system.
q Bleed air according to the following procedure.
q Carefully monitor fluid level at reservoir tank during bleeding CL
operation.
q When bleeding the air from the clutch fluid, first bleed the air
from the operating cylinder air bleed valve and then from the D
bleed connector air bleed valve.
1. Top off reservoir with new recommended brake fluid.
2. Connect a transparent vinyl tube to the air bleeder valve on the E
clutch operating cylinder.
3. Fully depress the clutch pedal several times. WCIA0018E
4. With clutch pedal depressed, open the bleeder valve to release F
air.
5. Close the bleeder valve.
6. Repeat steps 3 through 5 until clear brake fluid comes out of the air bleeder valve. G
