How to Check for Clutch Failure?

[LaAshlyn]

Here are the methods to check for clutch failure: 1. Check if the driven plate can be turned easily. Remove the clutch bottom cover, shift the transmission into neutral, fully depress the clutch pedal, and then use a screwdriver to turn the driven plate. If it turns easily, the clutch disengages properly; if it doesn't turn, the clutch is not fully disengaged. 2. Check if the clutch pedal free play is too large and adjust it. 3. Check if the release lever heights are consistent and not too low. Under the vehicle, move the release fork so that the front end of the release bearing lightly touches the inner end of the release lever. Rotate the clutch one full turn to inspect. If the inner ends of the release levers do not simultaneously contact the release bearing, the release lever heights are inconsistent and should be adjusted. If the release lever heights are consistent but the clutch still doesn't fully disengage, check the lever height. Adjust all release levers to the same height. If the clutch then fully disengages, it indicates improper previous adjustment or excessive wear. After adjusting the release levers, the clutch pedal free play must be readjusted. 4. If the clutch still doesn't fully disengage after the above adjustments, remove the clutch and check if the driven plate is installed backward, if axial movement is difficult, if the main and driven plates are warped, if the release lever screws are loose, or if the floating pins are missing. 5. For clutches with newly riveted friction plates, check if the driven plate and friction plates are too thick. If they are, add shims between the clutch cover and flywheel. 6. For hydraulically operated clutches, in addition to the above checks, also check if the brake fluid is low, if there are any leaks in the pipes, and bleed the air from the hydraulic system.
