On modern vehicles it is becoming increasingly common that when a clutch is replaced the concentric slave cylinder (CSC) also requires replacement.
The assembly of a concentric slave cylinder is structured to allow it to operate directly in front of the clutch cover.
This new technology allows direct hydraulic load to be applied to the clutch via the master cylinder and concentric slave cylinder. As a result providing less pedal pressure, eliminating the potential loss of bearing travel caused by wear commonly associated in traditional linkage or cable type systems.
At Mr Clutch we recommend fitting a new concentric slave cylinder whenever performing a clutch replacement in vehicles where these units are used. Failure to do so may cause damage to the new clutch, resulting in expensive rework.
Advantages of CSCs:
- Lighter pedal pressures allowing a more comfortable drive
- Self adjusting system prolonging the life of your clutch
- Less moving parts which means there are less items to wear or fail.
The flywheel is a metal disc which is fitted directly onto the crankshaft between the engine and the clutch. Its purpose is to help provide a smooth transfer of power from the engine to the drive train. In essence, the flywheel gives your vehicle enhanced momentum and a smoother driving experience.
Indications of a worn flywheel are:
- Visible Grooves
- Visible glazing and/or cracks
We, along with the leading clutch manufacturers worldwide, recommend that whenever a clutch is renewed, your flywheel should be inspected and, where necessary, skimmed or replaced.
Dual Mass Flywheel
Most new vehicles now come fitted with dual mass flywheels. These are essential components that allow an enhanced performance in the vehicles drivability. Additionally, these new components reduce harmful vibration.
A worn dual mass flywheel will affect the performance and efficiency of the new clutch and almost certainly result in premature failure.
Indications of a worn Dual Mass Fhywheel are:
- Irregular noises
- Vibration
- Intermittent clutch slip
A standard clutch assembly comprises of several different parts that fit together and assist in helping you to change gear and pull away smoothly. These are the clutch cover, clutch plate, pressure plate, clutch fork, clutch cable or hydraulic system and bearing. There is one other vital component called the flywheel that sits next to the engine and this helps keep the clutch and engine spinning at the same time.
When you are driving and your foot is off the pedal, springs force the pressure plate to push the clutch plate against the flywheel. Because there is a high level of friction between the clutch plate and flywheel this keeps the engine and clutch turning over at the same speed.
When you press the clutch down, the clutch cable or hydraulic system pushes the clutch fork forward, which in turn presses the bearing onto the diaphragm in the clutch cover. The diaphragm then pulls the pressure plate away from the clutch plate which disengages the clutch from the flywheel and engine allowing you to change gear.
Thank you for trusting Mr Clutch Autocentres with your vehicle
Take the time to read all the information below. It has been provided to help you understand why your vehicle may drive differently since the repair. If you find you have an unexplained problem please don’t hesitate to contact your local Autocentre so they can investigate. For your nearest Mr Clutch Autocentre call 0800 67 67 67.
Following your Clutch Replacement
After your clutch is replaced, Mr Clutch Autocentres recommend a bedding-in period of 500 miles. During this period you should release the clutch gently. You will find the ‘biting point’ and the pressure of the clutch pedal has changed, it may be ‘fierce’ as it is engaged.
Whilst all efforts are made to identify every potential problem, not all are apparent at the time of repair. If you find you need further assistance please contact your local Autocentre.
Warranty Terms — please read carefully
Mr Clutch trained technicians use high quality components during repair or replacement, but faults can occur. In the event you have a problem, please don’t panic, simply contact your local Autocentre so that they can investigate the problem.
- Components:
- All our complete clutch kits carry a warranty against manufacturing defects for a period of two years or 20,000 miles, whichever is sooner (from the original invoice date). Except vehicles for commercial use i.e. taxis, driving schools and light commercial vehicles which carry one year or 12,000 miles.
- Modified vehicles could render the warranty invalid.
- Any other parts supplied carry the manufacturer’s warranty only.
- The warranty becomes void if:
- the replaced component is misused
- clutch adjustments are not carried out by a Mr Clutch Autocentre at 500, 3,000, 6,000, 12,000 miles. Please present your invoice when returning your vehicle for each adjustment.
- A subsequent component failure is caused by other fault parts, (e.g. hydraulics, clutch forks, clutch or brake cables) which were not apparent at the time of the component replacement.
- A subsequent component failure is caused by other faulty parts that have been reported on your vehicle, but have not been rectified.
- Failure is as a result of undue wear and tear.
- You do not produce your invoice when making a claim under this warranty.
- We accept no responsibility for any subsequent part failures that were not apparent at time of inspection.
- In the event of a component failure during the warranty:
- You must immediately inform the Mr Clutch Autocentre that carried out the original replacement.
- It is your responsibility to return the vehicle to a Mr Clutch Autocentre for inspection/repair as soon as possible after such notification.
- If we repair or exchange the faulty part concerned, the original warranty period is not extended.
- This warranty does not affect your statutory rights.
