In a manual transmission, the clutch is disengaged as you press the pedal down. Now, the pedal works the thrust pad and presses levers in the middle of the clutch cover. In the process, the pressure plate is lifted away from the clutch plate while the flywheel turned by the crankshaft from the transmission shaft gets disconnected. When the pedal is lifted, the springs force the pressure plate and clutch plate against the flywheel. It is then allowed by the clutch plate friction linings to slide before it gets engaged.

Basically, contained in a pressure plate like the ACT pressure place are the clutch plate, springs, cover and release fingers. With the clutch disc sandwiched in between, the subassembly of the pressure plate is bolted to the wheel. There are actually two types of pressure plate – the spring type and the most commonly used diaphragm-type. The purpose of the pressure plate is to apply pressure to the clutch disc necessary for the transfer of torque to the transmission. When it is coupled with the clutch disc and flywheel, the pressure plate makes and breaks the flow of the power from the engine to the transmission.

Clutch chatter is a typical symptom when a clutch is damaged. You should not however be conclusive enough as this symptom could also be caused by oil leaking from the engine onto the clutch assembly, a poor flywheel surface, damaged pressure plate release levers, a sprung clutch disc hub and improper alignment between the engine and transmission. Clutch slippage is another common clutch problem. This results from different factors such as a worn pressure plate, worn, binding or misadjusted linkage, improper clutch components, and even normal wear.
