Clutch Release Bearing: Description and Operation

CLUTCH RELEASE BEARING AND LEVER

DESCRIPTION





A conventional release bearing is used to engage and disengage the clutch pressure plate. The clutch release bearing is mounted on the transaxle front bearing retainer. The bearing is attached to and operated by the release lever (Fig. 8), which moves the bearing into contact with the clutch cover diaphragm spring.

OPERATION
The release bearing is operated by the release lever (Fig. 8). Pressure applied to the clutch pedal transmits force through the clutch cable, causing the release lever to move the release bearing into contact with the diaphragm spring. As additional force is applied, the bearing presses the diaphragm spring fingers inward on the fulcrums. This action moves the pressure plate rearward, relieving clamping force on the clutch disc. Releasing pedal pressure reduces the force applied to the release lever. The release bearing then moves away from the diaphragm spring which allows the pressure plate to exert clamping force on the clutch disc.
