Inspection and Adjustment
INFOID:0000000001731683
INSPECTION
1.
Make sure that clevis pin (1) floats freely in the bore of clutch
pedal. It should not be bound by clevis or clutch pedal.
a.
If clevis pin is not free, make sure that ASCD clutch switch (2) is
not applying pressure to clutch pedal causing clevis pin to bind.
To adjust, loosen lock nut (3) and turn ASCD clutch switch.
b.
Tighten lock nut. Refer to
c.
Make sure that clevis pin floats in the 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 (bushing, clutch pedal assembly, etc.). Reassemble clutch
pedal and again make sure that clevis pin floats freely in the bore of clutch pedal.
3.
Check clutch hydraulic and system components (clutch master cylinder, CSC, 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
ADJUSTMENT

CLUTCH FLUID
Inspection
INFOID:0000000001731684
CLUTCH FLUID LEVEL
• Check that the fluid level in the reservoir tank is within the specified
range (MAX – MIN lines).
• Visually check for any clutch fluid leakage around the reservoir
tank.
• Check the clutch system for any leakage if the fluid level is
extremely low (lower than MIN).
Air Bleeding Procedure
INFOID:0000000001731685
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.
NOTE:
Do not use a vacuum assist or any other type of power bleeder on this system. Use of vacuum assist or power
bleeder will not purge all the air from the system.
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.
