- Clutch cover assembly failure
- Clutch driven plate worn
- Clutch driven plate contaminated with oil
- Flywheel damaged/worn
- Clutch worn excessively - Cover assembly adjuster ring set to the fully worn position
- Clutch temperature excessively high
|
- GO to PINPOINT TEST A .

- Allow the clutch temperature to return to normal and retest
|
| Clutch chatter or shudder |
- Engine/transmission mounting loose/damaged
- Clutch driven plate contaminated with oil
- Clutch cover assembly failure
- Clutch driven plate worn/warped
|
NOTE:
- If a new clutch assembly is installed in the unreleased position, some clutch judder may be experienced.
- If a new clutch assembly is installed, the new unit should be bedded-in (this may be accomplished through 1 hour of in-town driving or similar).
|

- Clutch pedal travel insufficient/obstructed
|
- GO to PINPOINT TEST C .
- Check that the clutch pedal can move through its full range of travel
|
| Clutch pedal pulsation |
- Clutch and brake pedal pivot shaft not correctly lubricated

|
NOTE:
- Some levels of vibration at higher engine speeds is normal.
- If a new clutch assembly is installed in the unreleased position, some clutch judder may be experienced.
- If a new clutch assembly is installed, the new unit should be bedded-in (this may be accomplished through 1 hour of in-town driving or similar).
|
| Clutch pedal related vibrations |
- The engine/transmission foul condition with the body/chassis
