Technician Handbook ! 302 Manual Transmissions & Transaxles Clutch Operation When the release bearing is pushed against the diaphragm spring, the spring folds inward and the pressure plate moves away from the clutch disc. Clutch engagement begins when the pressure plate of the clutch cover and flywheel begin to rub against the clutch disc. The amount of torque transferred to the clutch increases as spring pressure against the pressure plate increases. When the clutch is engaged, pressure from the clutch cover diaphragm forces the pressure plate against the clutch disc and flywheel. Technical Training 19
