Knowing when to change your clutch plates

A clutch is a mechanical device that controls the engaging and disengaging from the engine crank shaft from transmission while shifting the gear, or to run the engine and idle speeds. It is flexible or releasable device that connects the ends of two coaxial shafts, one of them being the crank shaft of the engine, and the other being an input shaft of a gear box.

The multi plate clutch assembly is made up of the clutch housing, clutch boss, clutch plates- friction plates and steel hubs, and the clutch hub with pressure plates and springs, bearings, bushes and oil seals.

The clutch assembly is placed between the transmission and input shaft, and when it is depressed, it helps to separate the input shaft and the transmission. The depression of the clutch forces the springs of the hub to compress. This results in reducing or loosening the contact of the friction plates and steel plates, which in turn allows the flywheel to rotate freely.

This is when the right gear can be chosen by the driver according to speed and other factors. Bike Clutch Plates are thus important parts for putting the bike’s engine into gear, allowing you to stop at any speed by disengaging the engine, and may even save your life in case of an engine seizure.

Out of the components listed above, the clutch plates and oil seals are the ones that have to be replaced often, whereas the others survive for longer. The signs that we really need to replace the clutch plates in our bikes are as follows.

• Clutch Slips

In a clutch slip, the friction between clutch plates and pressure plates are not enough as they diminish and cause the loss of torque and power. It can be felt when you twist the throttle hard, but don’t get enough power at the rear wheel.

• Clutch Drag/ Burn

In this case, the friction between clutch plates and pressure plates is more than required, which leads to difficulty in disengagement. This is caused by stickiness of melted friction surfaces. In extreme cases, the friction surfaces can start burning due to overheating.

• Clutch Judder

While many drivers mistake this to be the power of the machine, this happens due to offensive engagement of the clutch. It causes a forward jumping, a judder caused due to unsmooth engagement with a vibration. It is not due to worn out clutch plates.

• Clutch rattle and knock

These are noises that the bike emits during idling and operating conditions and needs to be examined carefully.

If you feel that your bike parts have been damaged and need repair, you may have to contact a bike clutch supplier or bike disc brake supplier, and get the parts replaced.
