Clutch Chatter Complaints

CLUTCH CHATTER COMPLAINTS

For all clutch chatter complaints, perform the following:

1. Check for loose, misaligned, or broken engine and transmission mounts. If present, they should be corrected at this time. Test vehicle for chatter. If chatter is gone, there is no need to go any further.
2. If chatter persists, check hydraulic clutch release system is functioning properly.
3. Check for loose connections in drivetrain. Correct any problems and determine if clutch chatter complaints have been satisfied. If not:
a. Remove transaxle.
b. Check to see if the release bearing is sticky or binding. Replace bearing, if needed.
c. Check linkage for excessive wear on the pivot stud and fork fingers. Replace all worn parts.
d. Check clutch assembly for contamination (dirt, oil). Replace clutch assembly, if required.
e. Check to see if the clutch disc hub splines are damaged. Replace with new clutch assembly, if necessary.
f. Check input shaft splines for damage. Replace, if necessary.
g. Check for uneven wear on clutch fingers.
h. Check for broken clutch cover diaphragm spring fingers. Replace with new clutch assembly, if necessary.
