What is the function of the clutch pressure plate?

The clutch pressure plate is an important part of your manual vehicle clutch system. It is a heavy metal plate controlled by springs and levers. Its main purpose is to apply pressure to the main clutch plate (or clutch disc) to make it close to the engine flywheel. This allows energy to flow from the engine crankshaft, into the gearbox/gearbox system through the engaged clutch, and then through the driveshaft to the wheels.

When the driver steps on the clutch pedal, the pressure plate stops applying pressure to the main clutch plate, thereby disengaging the clutch pressure plate, the clutch plate and the engine flywheel (eliminating friction pressure). This interrupts the transmission of engine power, allowing the driver to easily engage and shift gears.

Clutch disc wear

Wear of the clutch disc/clutch plate will damage the clutch pressure plate. Once the bushing is completely worn from the clutch disc/clutch plate, the rivets or other metal parts on the clutch plate will rub directly on the pressure plate.

Broken finger or spring

If one or more clutch pressure plates protruding from the center of the clutch plate are broken or bent, the clutch will not work properly and it may become difficult to engage the gears. In addition, if the spring device of the clutch pressure plate is damaged, you may not be able to engage or disengage the clutch and gear at all.

Incorrect installation

It is important that a certain distance must be maintained between the pressure plate and its release bearing. If part of the clutch is installed incorrectly, the thrust bearing may damage the clutch pressure plate.

Clutch cable adjustment is incorrect

If the clutch cable is over-tightened, the clutch thrust bearing may continue to press on the clutch pressure plate, resulting in continuous slight clutch slippage and damage.

Improper use of the clutch

If the clutch is used improperly, the clutch pressure plate may be damaged. Examples of improper use include overriding the clutch when starting on a hill, slipping gears, or using the clutch to slow the vehicle through engine braking.
