This is a six-pin sprocket used in many models of chainsaws. The sprocket is an integral component of a chainsaw since it drives the chain on the machine, transfering the power to the chain so it can cut through wood effectively. Due to the high speeds and vibrations created by the chain, this item may become worn out and need to be replaced. The best way to determine whether the sprocket is worn out is by manually rotating the chain on the chainsaw. If the chain is tensioned correctly and the chain rotates smoothly before becoming loose or hard to turn, the sprocket likely has worn teeth. This can be checked by loosening the bar nuts and taking off the bar, chain, and cover. The sprockets will be exposed and an inspection can be done visually. Look for teeth that are grooved or notched, which indicates the sprocket will need to be replaced.This six-pin sprocket is a genuine OEM replacement part that is sourced directly from the manufacturer. The component is sold individually. The sprocket is compatible with various chainsaws manufactured by Craftsman, Poulan, and Poulan Pro.
