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.

What is a Clutch and what does it do

How Does it 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 is it Made?

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

Why Does it Fail?

  • Friction material on the disc wears out
  • High RPM engagement
  • Slipping the clutch during engagement
  • Harsh or high-speed downshifting
  • Lugging the clutch
  • Excessive vehicle loading
  • Riding the clutch
  • Disengaging clutch while in gear
  • Over-revving the engine
  • Engine, transmission and suspension modifications

What are the Symptoms of Failure?

  • Release problems
  • Noise
  • Chatter
  • Slipping
  • Hard pedal

What are the Implications of 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.
