Part #640200214
This authentic OEM rim sprocket in your chainsaw transfers power from the engine to the cutting chain. It is typically located at the center of the clutch drum, situated at the end of the engine crankshaft. By engaging with the chain drive links, it enables the chain to rotate and cut through materials as the engine turns. You will notice that if the rim sprocket is broken that the chain slips, does not engage, or rotates unevenly. It may also reveal signs of wear such as worn-out teeth. Failure to replace a broken rim sprocket can result in reduced cutting power, chain damage, and increased strain on the engine. To remove the rim sprocket, first, loosen the chain tension by adjusting the tensioning screw or knob. Then, remove the guide bar by loosening the nuts or clips on the side cover and sliding the guide bar off the saw. Use a screwdriver or appropriate tool to remove the screws or fasteners securing the clutch cover. With the clutch cover removed, you can access the clutch drum.

Ordered on/off switch. My switch had only one wire terminal. Replacement had two. I ran a wire from one to a screw as a ground. Switch worked fine.
