Pedal failure
1、 Fault phenomenon: When the engine is idling, although the clutch pedal has been pressed to the bottom, it is difficult to engage the gear, and the transmission gear makes a noise. After barely shifting into gear, the clutch pedal has not been released, and the car has driven or stalled.
2、 Check: Remove the bottom cover of the clutch, shift the transmission into neutral gear, and step the clutch to the bottom. Then, use a screwdriver to move the driven plate. If it can be easily rotated, it indicates that the clutch is well disengaged; If it cannot be turned, it means that the clutch is not completely disengaged.
3、 Exclude:
1. Check whether the free stroke of the clutch pedal is too large and adjust it.
2. Check whether the release lever height is consistent and too low. Move the release fork under the vehicle to make the front end of the release bearing gently lean against the inner end face of the release lever, and turn the clutch for a week to check. If the inner end of the release lever can not contact the release bearing at the same time, it indicates that the height of the release lever is inconsistent and should be adjusted. If the height of the release lever is consistent and the release is still incomplete, check the height of the lever. Adjust each release lever to the same height. If it can be completely separated, it indicates that the original adjustment is improper or it is too worn. After the release lever is adjusted, the free stroke of the clutch pedal must be readjusted.
3. If the above adjustment is normal and the separation is still incomplete, remove the clutch and check whether the driven plate is installed reversely, whether it is difficult to move axially, whether the driven and driven plates are warped, whether the release lever screw is loose, and whether the floating pin falls off.
4. For the clutch of newly riveted friction plate, check whether the driven plate and friction plate are too thick. If it is too thick, add shims between the clutch cover and flywheel.
5. For the hydraulic clutch, in addition to the above inspection, check whether the brake fluid is lacking, whether the pipeline leaks and exhaust the air in the hydraulic system.
