CLUTCH PEDAL
CLUTCH PEDAL |
PFP:46540 |
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.
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 nut.
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
PCIB0907E
deformation or damage. Replace clevis pin if necessary. Leave the 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.) 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 |
|
|
|
|
||||
|
clutch interlock switch) |
|
|
|
|
Clearance “C”: |
0.3 - 1.0mm (0.012 - 0.039 in) |
||
4.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-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 the air from the system.
