Mechanical car clutches are any of various devices for engaging and disengaging two moving parts of a shaft, or of a shaft and a driving mechanism. While many things contain clutches of some sort, we’ll be focusing on the type that sits between the engine and the transmission of an automobile equipped with a manual transmission.

While the clutch is engaged, everything spins as one unit. When you press the clutch pedal in, the clutch assembly is disengaged. The shaft and clutch disc spin independently of the flywheel and pressure plate.

As you let the clutch pedal out, the friction surfaces on both sides of the clutch disc begin to make contact with the metal surfaces of the flywheel and pressure plate, and the power of the engine is transferred through the transmission input shaft, through the gears and right down onto the road.

The tricky part is matching up the speed of the engine to the engagement of the friction surfaces so you don’t get caught in the clutches of a potentially embarrassing engine stall.

Now you see how important your CLUTCH is, so always check them
