The main components of a single plate push-type clutch are the clutch discs, the clutch cover, the clutch fork, and the release bearing. The clutch discs are splined to the transmission input shaft. The clutch discs slide back and forth as the clutch is engaged and disengaged. When the clutch is disengaged, the clutch discs float between the pressure plate and the flywheel. During engagement, the clutch disc is clamped firmly against the flywheel by the pressure plate spring in the clutch cover assembly.

The clutch disc has friction material on both sides and a spring-loaded drive disc that absorbs torsional vibration and shock loads. The clutch cover has a machined surface used to clamp the discs against the drive plate. The springs hold the pressure plate and the driven plate together against the flywheel when the clutch is engaged.

The release bearing is a ball-thrust bearing on a sleeve. When the release bearing is pushed on the release levers, the clutch disc will disengage. As the driver allows the clutch pedal to rise, the release bearing starts to return to the in-rest position. When the release levers rise, the pressure spring expands and clamps the discs against the flywheel.

The clutch operating controls include a pendant-type pedal return spring, cable, and a clutch release fork. When the clutch pedal is depressed, the cable activates the clutch release fork. The clutch release fork presses the throw-out bearing against the clutch release fingers and releases the clutch.

The main components of a pull type clutch are the clutch discs, the clutch cover, the strap drive intermediate plate, and the clutch yoke. The clutch disc/s is/are splined to the transmission input shaft in order to slide back and forth as the clutch is engaged and disengaged. When the clutch is disengaged on the single plate clutch, the clutch discs floats between the flywheel and the pressure plate.

The two-plate discs float between the flywheel, the intermediate plate and the intermediate pressure plate. During engagement, the clutch discs are clamped firmly between the flywheel, the intermediate plate, and the clutch cover. The pressure plate spring in the clutch cover assembly provides clamping force.

The clutch discs have friction material on both sides and a dual-staged spring dampened drive disc that absorbs torsional vibration and shock loads. The clutch cover has a machined surface that is used to clamp the discs and the intermediate plate with springs located between the cover and the pressure plate. The springs hold the pressure plate and the driven plate together against the engine flywheel when the clutch is engaged.

When the clutch pedal is depressed, the release bearing is pulled rearward and pulls the clutch cover release levers in order to disengage the clutch discs and the intermediate plate. The disengaged clutch discs and the intermediate plate float free. The pressure plate retracts the pressure plate into the clutch cover causing the springs to compress, allowing the discs to float freely.

When the clutch pedal is released, the release bearing returns to the in-rest position and the release levers drop. When the release levers drop, the pressure springs expand and clamps the discs against the flywheel. The clutch operating controls include the pendant-type pedal return springs, the cable, and a clutch release mechanism. When the clutch pedal is depressed, the cable activates the clutch release mechanism.
