The clutch is the vital link delivering engine power to the transmission. The role of the clutch is to effortlessly transfer the power from the engine to propel the vehicle. It really is the vital link between the power source (engine) and the power distribution (transmission, differential, axles and wheels). The functions of the clutch include:
- The ability to cut engine power quickly for safe driving
- Smooth, quiet transfer of engine power to transmission
- Quick radiation of frictional heating
- Maintaining inertia after disengagement
- Making full use of the engine's power
In manual transmissions, the clutch engages and disengages the engine from the transmission as you change up and down gears or into reverse. This constant use when driving means clutches are prone to wear, and eventually need replacement.
Signs you might have a worn clutch are:
- Poor acceleration
- Increase in fuel consumption
- Speed doesn't pick up quickly compared to amount of acceleration
- Poor power when climbing hills
