Coil Spring Pressure Plate
The coil spring pressure plate uses small coil springs similar to valve springs (Figure 10- 5). The face of the pressure plate is a large, flat ring that contacts the clutch disc during clutch engagement. The back side of the pressure plate has pockets for the coil springs and brackets for hinging the release levers. During clutch action, the pressure plate moves back and forth inside the clutch cover. The release levers are hinged inside the pressure plate to pry on and move the pressure plate face away from the clutch disc and flywheel. Small clip-type springs fit around the release levers to keep them rattling when fully released. The pressure plate cover fits over the springs, the release levers, and the pressure plate face. Its main purpose is to hold the assembly together. Holes around the outer edge of the cover are for bolting the pressure plate to the flywheel.
