On-Vehicle Inspection and AdjustmentNCS00006
1. Check to see if the 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 clevis pin is not free, check that the pedal stopper bolt or
ASCD clutch switch is not applying pressure to the clutch pedal
causing the clevis pin to bind. To adjust, loosen lock nut and turn
pedal stopper bolt or ASCD clutch switch.
b. Tighten the lock nut. Refer to CL-6, "
Removal and Installation" .
c. Verify that the clevis pin floats in the bore of the clutch pedal. It
should not be bound by the clutch pedal.
d. If the clevis pin is still not free, remove the clevis pin and check
for deformation or damage. Replace clevis pin if necessary.
Leave pin removed for step 2.
2. Check clutch pedal stroke for free range of movement.
a. With the clevis pin removed, manually move the clutch pedal up and down to determine if it moves freely.
b. If any sticking is noted, replace the related parts (clutch pedal assembly, bushing etc.). Re-assemble the
clutch pedal and re-verify that the clevis pin floats freely in the bore of the clutch pedal.
3. Adjust clearance “C” while depressing clutch pedal fully. (With
clutch interlock switch)
4. Check clutch hydraulic and system components (clutch master
cylinder, CSC, etc.) for sticking or binding.
a. If any sticking or binding noted, repair or replace related parts as
necessary.
b. If hydraulic system repair was necessary, bleed the clutch
hydraulic system. Refer to CL-7, "
Bleeding" .
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.Clearance C : 0.1 - 1.0 mm (0.004 - 0.039 in)

Disassembly and AssemblyNCS0000A
DISASSEMBLY
1. Remove spring pin, nipple and reservoir seal from cylinder body
using a pin punch.
2. Loosen push rod lock nut. Remove clevis and lock nut.
3. Remove the seat from the cylinder body.
4. Remove the stopper ring and stopper, and then remove the
push rod, piston assembly and return spring from the cylinder
body.
CAUTION:
Restrain the push rod while doing this because there is a
danger the piston assembly will fly out of the cylinder body.
