This is a ten (10) pin sprocket assembled by original manufacturer. It is used in some Makita planers. Sprockets engage gears and/or chains. These parts are designed to be replaced fairly often due to wear and tear from regular use. Sold individually.
1. Removed the side panel that covers the drive chain.
2. Removed the spring that holds the drive chain snug against the sprockets.

1. Remove the side cover

8. Replace the cover
