This is an OEM sourced replacement part used on Poulan chainsaws. A centrifugal clutch uses centrifugal force to connect two concentric shafts, with the driving shaft nested inside the driven shaft. Often centrifugal clutches will function even when they shouldn’t, far beyond the point of when they need to be replaced. Keeping an eye on equipment performance will determine when the clutch requires attention. This assembly includes metal clutch drum and a sprocket.

To replace this item you would need a wrench set.

• Remove the chain brake, bar, and chain.
• Remove the cover and spark plug.
• Bind the piston. (If you skip this step, the clutch will spin freely and you won’t be able to remove it. If you have a piston stopper, just thread it into the spark plug hole. )
• Remove the clutch.
• Replace old drum with a new assembly
• Seat the clutch.
• Unbind the piston.
• Secure the bar, chain, and chain brake.
• Tension the chain
