Hidden behind the sprocket cover, the chain sprocket is the driving force behind the chain. A seriously worn chain sprocket can cause the chainsaw chain and guide bar to wear at an increased rate, as well as reducing cutting performance too, so it’s important to keep an eye on. If the groove depth is too small, the tips of the drive links will scrape along the bottom and drastically impact how smoothly the chain moves around the guide bar.
A spur sprocket is a single piece of metal that has sprocket teeth made directly onto the clutch bell housing of the sprocket. Rim Sprocket Systems are typically used by professionals and chainsaw enthusiasts who cut large amounts of wood. Replacement rims typically cost around $7 while a whole Rim Sprocket System costs around $30. Properly maintaining your chainsaw will save you a ton of time and money down the line.
Replace a chainsaw drive sprocket after wearing out two chains or if it is damaged.

Pro Tips If your chainsaw uses a rim-type drive sprocket, add a spare sprocket and retaining clip to your field service kit.
Chainsaw Sprocket – Maintenance & PerformanceA chainsaw sprocket plays a key part in the performance of a chainsaw. Chainsaw drive sprocket maintenance Worn out sprockets not only affect the efficiency and working of your chainsaw but can result in wear on all the other components connected to it. Even though sprocket maintenance is such as an important aspect of overall chainsaw maintenance, many tree professions tend to overlook it.
In my opinion some people change sprockets too often and others seem to never change them at all until they wear clean through. It’s hard to recommend replacing the sprocket after so many chains because some people can file a chain and can use one chain for a long time, while others end up replacing a chain after a few failed attempts at sharpening. Most sprockets have a little horizantal line on each side of the driver holes of the sprocket.
