CLUTCH PEDAL


Inspection and Adjustment






1. Check to see if the master cylinder rod end moves freely. It should not be bound by the clutch pedal.
- If the rod end does not move freely, remove the rod end and check for deformation or damage on the rod end. Leave the rod end removed for step 2.
2. Check the clutch pedal stroke for free range of movement.
a. With the master cylinder rod end removed, manually move the clutch pedal up and down to determine if it moves freely.
b. If any sticking is noted, replace the clutch pedal assembly.
Reverify that the master cylinder rod end moves freely.
3. Inspect the ASCD clutch switch position.
a. If the rod end does not move freely, check that the ASCD clutch switch is not applying pressure to the clutch pedal causing the rod end to bind. To adjust, disconnect the ASCD clutch switch electrical connector and turn the ASCD clutch switch.
b. Connect the ASCD clutch switch electrical connector.





4. Adjust clutch interlock switch (1) position so that clearance between clutch pedal (2) and thread end of clutch interlock switch (1), with clutch pedal fully depressed, is within specification (C).

Clearance C : 0.74 - 1.96 mm (0.0291 - 0.0772 in)






5. Adjust ASCD clutch switch (1) position so that clearance between clutch pedal (2) and thread end of ASCD clutch switch
(1), with clutch pedal fully released, is within specification (A).

Clearance A : 0.74 - 1.96 mm (0.0291 - 0.0772 in)


6. Check the clutch hydraulic system components (clutch master cylinder, CSC) for sticking or binding.
a. If any sticking or binding is noted, repair or replace the related parts as necessary.
b. If any hydraulic system repair was necessary, bleed the clutch hydraulic system. Service and Repair.
