Are chainsaw sprockets interchangeable?
Chain pitch is the length of the links in the chain. Both sprockets fit only a single chain pitch, so for the powerhead–bar–chain combination to work, their design chain pitch must be the same. Chainsaw drive sprocket on the powerhead and the nose sprocket of the guide bar are pitch-specific.
How do I know if my chainsaw sprocket is bad?
Look closely at the teeth of the sprocket for signs of a groove or notches. The teeth are supposed to be smooth and consistent. If you noticed that there is a groove worn in the teeth and the chain will not rotate consistently smooth, it’s time to replace the sprocket.

Why must the sprocket and chain be matched for pitch?
Rim Sprockets use a pocket that must be wide enough to allow the drive tangs to seat. Pitch is the length of the links that make up the chain, basically the distance spanned by three rivets divided by 2 and chain pitch must match the sprocket pitch so the chain is properly driven.
