CLUTCH

At the most basic level, a clutch connects and disconnects your engine from your transmission (and everything else) in your car or truck. Your engine is constantly turning, and the clutch helps to transmit this power to your gearbox, so that you can successfully shift gears.

How do Clutches Work?

The clutch system consists of a pressure plate, disc, release bearing and pilot bearing. The disc contains various springs to smooth clutch engagement and dampen vibrations. The friction material is riveted to numerous cushion segments, which are known as marcels. Subtle waves in the marcels soften clutch engagement. Flywheel is also part of the system, though it is actually connected to the engine, while the other parts listed previously are connected to the transmission. When the clutch is disengaged (the clutch pedal pushed in), the pressure plate lifts away slightly from the flywheel, interrupting the flow of power from the engine to the transmission. Bringing the pedal back up re-engages the pressure plate with the flywheel, which in turn reconnects the engine to the transmission and drive wheels.

How are Clutches Made?

  • Precise engineering and close manufacturing tolerances
  • Forged heat treatment – case hardening and induction hardening
  • Machining – shaping, drilling, milling and reaming
  • Assembly

How Can a clutch Fail?

  • Falls out of adjustment
  • Becomes contaminated
  • Floods
  • Leaks

What Are the Symptoms of Failure?

  • Poor engine performance
  • Black smoke due to incorrect mixture
  • Overheating

What are Implications of Car Light Failure?

  • Though technically it is possible to drive a car with a clutch that is failing, doing so puts other components at risk and the performance of the clutch will continue to decline. It’s best to have the vehicle inspected by a qualifi ed technician as soon as the failure symptoms begin to appear.
