Affected Vehicles
Condition
^ Clutch not operating properly.
^ Clutch smells burnt.
^ Clutch pedal does not fully return to starting position.
Technical Background
The following conditions can lead to clutch damage:
^ Incorrect shifting.
^ At a high vehicle speed, the clutch is pressed and an incorrect lower gear is selected. The gearbox drives the clutch plate past its designed RPM
range (over speed condition) and centrifugal force damages the clutch. If the clutch was engaged during this incorrect gear engagement, damage
would also occur to the engine.
^ The revolutions of clutch plate and engine input shaft differ too much.
^ Excessive slipping of the clutch.
This leads to the overheating of the clutch plate and removal of the lining.
Production Solution
Not Applicable.
