Examination
1. Visually verify that the clutch master cylinder rod end moves freely without binding.
If the rod tip does not move freely, remove it from the clutch pedal and check for deformation or damage. Leave the clutch master cylinder rod end removed for the next step.
2. Make sure that the clutch pedal moves freely throughout its entire travel:
After disengaging the clutch master cylinder, move the clutch pedal up and down by hand to make sure it moves freely.
If any jamming is found, it must be replaced with a new one. Check again that the clutch master cylinder rod end moves freely.
3. Check the position of the ASCD switch (automatic speed control):
If the clutch master cylinder rod tip does not move freely, check that the ASCD switch does not apply pressure to the clutch pedal causing the rod tip to jam. To adjust the position of the switch, disconnect the electrical connector and rotate the ASCD switch.
Connect the ASCD switch electrical connector.
4. Check clutch hydraulic components (clutch master cylinder, concentric release cylinder) for jamming or jamming.
If any jamming or jamming is found, eliminate the cause of the malfunction or replace the parts with new ones.
If repairs are required on any of the clutch hydraulic components, perform the Clutch Bleeding Procedure after the repair is complete.
Note. Do not use a vacuum bleeder or any other type of special tool to force-bleed the clutch hydraulics as they will not completely remove air from the system.
Adjustment
Adjust the position of the ASCD switch (1) so that the gap «A» between the clutch pedal (2) and the threaded part of the ASCD switch, with the pedal fully released, corresponded to the set value (0.74-1.96mm).
