Description:
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

Easy
Time Spent Repairing:

Tools Used:
Screwdriver, Pliers, Piston stop
The chain drive sprocket had broken teeth and the whole drum assembly needed to be replaced. Also, while I had the saw apart, I decided to install a new filter, and a new chain tensioner.
The chain tension kit and the filter were simple replacements, but the drum assembly was a small challenge. I removed the out cover to expose the drum assembly. You Tube has some good videos connected with replacing the drum assembly, but basically you have to use a piston stop of some sorts. The pros suggest using a piece of cord to jam the piston, but this did not work for me. Instead, I removed the spark plug and used a wooden dowel slightly smaller than the spark plug hole. This worked well and were no concerns in ruining the piston or rings. Once the piston is arrested you will note that the retainer has reverse threads. Most drum assemblies are marked to show which direction to either tighten or loosen the retainer. simply use a screwdriver or whatever to knock the retainer loose and back it off. Once the retainer is off it is simple to replace the assembly, taking note of any washers or bushings that were removed in sequence. Replace the chain and cover and then re-tension the chain. Save yourself a lot of money doing it yourself. I am a logger and the professional chains I use are very hard on the drive sprocket. Now that I know how to do this, it will save me hundreds of dollars a year. My parts arrived quickly and were to exact specifications.
