PRECAUTIONS

PRECAUTIONS PFP:00001

Service Notice or Precautions ACS007HL

q Recommended clutch fluid is brake fluid "DOT 3". Refer to MA-10, "RECOMMENDED FLUIDS AND
LUBRICANTS" .
q Do not reuse drained clutch fluid.
q Be careful not to splash clutch fluid on painted areas.
q Use a flare nut wrench, when removing and installing clutch pip-
ing.
q Use new clutch fluid to clean or wash all parts of master cylinder
and operating cylinder.
q Do not use mineral oils such as gasoline or kerosene. It will cor-
rode the rubber parts of the hydraulic system.
WARNING:
After cleaning clutch disc, wipe it with a dust collector. Do not
use compressed air.

On-Vehicle Inspection and Adjustment ACS007XI

1. Make sure that clevis pin floats freely in the bore of clutch pedal.
It should not be bound by clevis or clutch pedal. B
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
CL
pedal stopper bolt or ASCD clutch switch.
b. Tighten lock nut.
c. Make sure that clevis pin floats in the bore of clutch pedal. It D
should not be bound by clutch pedal.
d. If clevis pin is still not free, remove clevis pin and check for PCIB0907E
deformation or damage. Replace clevis pin if necessary. Leave
the pin removed for step 2. E
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.
F
b. If any sticking is found, replace related parts (clutch pedal bracket, assist spring, bushing etc.) Re-assem-
ble clutch pedal and again make sure that clevis pin floats freely in the bore of clutch pedal.
3. Adjust clearance "C" while depressing clutch pedal fully. (With
G
clutch interlock switch)
Clearance "C": 0.3 - 1.0mm (0.012 - 0.039 in)
4. Check clutch hydraulic and system components (clutch master H
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 I
as necessary.
b. If hydraulic system repair was necessary, bleed the clutch
hydraulic system. Refer to CL-7, "Air Bleeding Procedure" . J
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 K
purge all the air from the system.
