Search for Clutch plate :

Manual gearbox allows the driver to feel the speed and the power of the vehicle, and enjoy the comfort while driving. Each driver can confirm how important the clutch system is, its motion depends on it primarily. One of the main elements of the system is the clutch disc, which, despite its fragility and small size, undergoes the power of the car, which can be quite significant.

The clutch disc is located in the middle of the pressure plate and flywheel. It is a kind of a junction of the transmission with the engine. Its work is considered the most important link in the chain of the system function as a whole. In its central section there are special slots that allow attaching the drive shaft to the gearbox output shaft. The thickness of the parts does not exceed eight millimeters. The disc is covered on both sides with a special friction material.

When driver presses the pedal, the clutch disc remains for some time in a stable position, then rotates with a speed of up to 6000 rotations per minute. This process brings to the heat up and friction of some elements, on which depends the work of the entire clutch. When the transfer of torque and the repulsion of the pressure plate occur, the clutch disc rotates on the transmission shaft. Its speed is gradually reduced to the moment the driver switches the speed. When he takes off his foot, all the ongoing processes contribute to the re-connection of engine and transmission.

Every driver must choose clutch spare parts with great care, because the performance of a vehicle depends on it directly. So if you need to buy a new clutch disc, you can do it in our online store. We can also offer you other parts for your car, such as brake hose, regulator, flywheel or fan.

What you need to know about clutch disc replacement: lifetime limits, common defects and their signs, tips and recommendations

Average service life of the clutch disc is about 100 000 – 120 000 operational kilometers. In most cases the component requires replacement because of broken or loose damping springs, cracks and delamination of friction pads, wear out of hub splines, deformation.

Signs of driven clutch disc defectare troubled gear shifting, large free movement of the clutch pedal, worsening of car dynamics and vibration at clutch turning on.

Driven disc diagnostics implies unit dismantling. This is a laborious process which requires gear box demounting. Performing of these works should be entrusted to service station specialists. A specialist will check the clutch disc for defects and measure its thickness.

Component replacement is performed at a service station as well. For this, specialists remove transmission components, the starter, clutch cables and speedometer cables, the shift knob and the gearbox. The clutch mechanism stays opened and the old driven disk can be removed. Special tools for disc and cover centering is needed for installation of a new part. It is recommended to replace the pressure disc and clutch bearing together with the driven disc, because these components are worn out at the same speed.
