Clutch Control System

Self-Adjusting

The clutch control system is self-adjusting. Clutch pedal motion is transmitted by clutch release lever cable (7535) to the clutch release shaft (7515) .

NOTE: After proper installation of the clutch release lever cable , adjustment is completed by pulling the clutch pedal (7519) to its upmost position.

• With the clutch pedal in the upmost position, the pawl is free of the quadrant and the quadrant position is governed by the position of the clutch release fingers, the quadrant being free to rotate independent of the clutch pedal .
• The adjuster load spring force ensures contact between the clutch release hub and bearing (7548) and the fingers. As the clutch disc facing wears, the fingers are gradually moved away from the flywheel (6375) and this movement is translated to the quadrant, adjusting the quadrant position relative to the clutch pedal , when the pawl is free of the quadrant.

During normal running position, the pawl is engaged with the quadrant, locking it to the clutch pedal . For the rest of the clutch pedal travel, the system works as a conventional system; the clutch pedal motion being transmitted to the release fingers. The quadrant remains locked to the clutch pedal during clutch pedal movement. Since the clutch release hub and bearing in this system is constant-running, transmission neutral rollover noise can be detected as such only by disengaging the clutch release hub and bearing from the clutch release fingers.

NOTE: Lift clutch pedal to the upmost position when connecting or disconnecting the clutch release lever cable .

This is best accomplished by disconnecting the clutch release lever cable from the clutch release shaft and moving the clutch release shaft away from the clutch release lever cable . If neutral noise is evident under this condition, it is coming from the transmission (7003) .

Noise associated with the clutch release hub and bearing /clutch system will be evident during all or some portion of clutch pedal travel.

The clutch is a Belleville spring-type clutch pressure plate (7563) and a multi-stage dampered clutch disc (7550) using a self-centering, constant-running clutch release hub and bearing .
