Mintaining your clucth disc

Riding or driving in a correct practice can reduce technical problem from your machine. For example driving in correct way can help maintaining you clutch disk. Here some newbie technical review about bike disc or also known as clutch plate.
First let's take a look at the thing first.

   

 So what this thing do? This clutch disc cover with frictional meterial that goes between flywheel and pressure plate. During engagedment of clutch this is squeezed between flywheel and pressure plate and power from engine transmited by disc's hub to input shaft of transmission. Refer here for more. You can refer to the below picture

Here i list some of factors that can cause cltch disc failure:

1. Incorrect gear selection of a low gear while driving at speed causes the driven plate to accelerate instantaneously to a speed far in excess of the facing burst strength due to the multiplication of the rotation speeds of the Gearbox and or Differential Ratios. The driven plate rotation speed is independent of the engine speed.
   
   
2. The clutch disc exceeds its facing burst speed limit  while  the clutch is disengaged for gear selection, and when  the clutch is re-engaged the facing can disintegrate completely. The Facing material becomes entwined and bound amongst the Pressure Plate (cover assembly) componentry and restricts the correct operation of the Clutch cover and its components.
   It is not possible for the driven plate material to disintegrate while it is firmly clamped between the pressure plate and the flywheel.
   Disintegration can only occur while a clutch is disengaged or slipping due to do faulty adjustment proceedure during installation.
   
   
3. Mis-Shifting a gear while driving at speed can also cause the plate to accelerate past its facing burst strength as per the previous paragraphs 1 & 2.
   
   
4. Tow-Starting or push starting a vehicle while in low Gear can  cause increased rotation of the driven disc and also cause the facing material to tear away from the clutch backing plates when the clutch is suddenly engaged.
   
   
5. Repeated harsh clutch engagement at high engine RPM can also cause the facing material to break away from the Backing plate or damage the clutch hub the stop pins-and blow out the compression springs  causing compete clutch disc failure.
   
   
6. Excessive clutch slippage while driving causes the facing materials to overheat resulting in disintegration and failure of Clutch Disc and Pressure plate assemblies due to contamination from the facing materials.
   
   
7. Simply dropping a clutch disc on the floor prior to or during installation can impact and easily crack the facing material after a short operational period.
   
   
8. Fitting a clutch to a vehicle which has had an engine performance modification which exceeds the designed torque ratings of the clutch and Clamp loading of the pressure plate will also  cause Premature clutch failure.
