Clutch Weights

A clutch with more weight try to hold a given RPM without any regard of how much or how little power is applied. By increasing the weights and springs only by 50% a lot of difference can be made in the action of the clutch.

How a Clutch Weight works
When the RPM increases, the clutch weights start transmitting power by overcoming the spring pressure with the centrifugal forces it had created, and by closing the pulley enough to employ the belt.

The clutch weights act as the speed-sensing component of the primary pulley. With the increase of the RPM, the squeezing force created by the clutch weights continues to increase.

Functions of Clutch Weight

• It will give a smooth power delivery.
• It improves the engine's tractability low to mid-RPM.

Materials used for making Clutch Weights
The two most commonly used materials for making Clutch Weights are:

• Titanium
• Aluminum
