Description

The clutch drum, which holds the clutch, is an essential part of a chainsaw. Gasoline-powered chainsaws are designed to be able to idle with the engine running without the circular chain moving around the bar, which is also called the blade or the arm. The chain started turning when the user pulls the throttle trigger so the gasoline to the carburetor is increased. As the engine RPMs increase, the clutch is designed to expand and engage the chain, pulling it around the bar. Many dynamic forces impact the clutch drum, including the revolving chain, the rapidly increasing and decreasing RPMs, and the vibrations of the engine. Thus, it is not unusual for the clutch to wear and eventually need to be replaced. Wear on the clutch typically signals wear or damage to the clutch drum as well. Signs of wear include the chain being slow to turn when the engine's RPMs increase dramatically or not turning at all. This drum is compatible with 40 different models of Echo and Shindaiwa chainsaws. It is extremely important for the sake of proper functioning as well as safety to substitute only OEM replacement parts, such as this one, for the original components.
