Clutch Kit Essentials


So you want to buy a new clutch kit, and are perhaps even thinking about installing it yourself?

Replacing a clutch is a big job, as well requiring a certain level of skill, we recommend that only the well-experienced undertake the job.


What’s In a Standard Clutch Kit?

Here are your clutch kit essentials, so that you know exactly what you’re getting in your clutch kit, and how it all fits together, without getting too technical.

A standard clutch kit will have three main components; the clutch cover assembly, clutch disc and release bearing.

Clutch Cover Assembly / Clutch Facing

The clutch cover assembly, is sometimes referred to as the ‘pressure plate’ but it actually has four main parts:

  • Pressure plate
  • Springs
  • Clutch cover &
  • Release arms

The clutch cover assembly mounts onto the flywheel and is its partner in providing a friction surface for the clutch.


Clutch Disc

The clutch disc is the ‘driven’ part of the clutch kit.
Your choice of clutch will be influenced by the type of driving that you do, and the clutch disc is where this choice of material is important.

There are two common materials for a clutch disc - organic and ceramic.

Generally, high performance driving is more suited to ceramic clutch discs, and everyday driving, to organic clutch discs. There are also cerametallic and carbon options, each using combinations of materials for high performance applications.

Release Bearing

The clutch release bearing is the bearing that releases the pressure plate, sometimes referred to as the ‘throw out bearing’.


Flywheel

Not included in a clutch kit, but nevertheless an important part of the clutch mechanism is the flywheel. The flywheel gives the clutch disc (contained within the Clutch Cover Assembly- see above) a friction surface.

This is why the surface of the flywheel is so important to the smooth function of the clutch. A flywheel can be resurfaced, or machined, which can get rid of minor cracks. Any major cracks or faults in the flywheel will indicate that a full replacement is required.


Clutch Linkage

Beyond the clutch itself are the links that exist between where your foot meets the clutch pedal. There are several different types of clutch linkage and there configuration will vary depending on the type of vehicle you drive.

They are cable linkages, mechanical linkages and hydraulic linkages.
