Disconnect power! And even off, the blades are very sharp, and will slice your fingers very easily. Keep your fingers away.
1. Remove the side cover
2. Notice the sprocket on the motor is stripped, and the bolt is loose. Poor assembly, or teenagers pushing the feed too much? Can't tell.
3. Remove the bad sprocket with an allen wrench.
4. Remove the sprocket farthest from the motor. This turned out to be the easiest way to get the chain back on, for me.
5. Install the new sprocket on the motor spindle, and wrap with the chain, around the tensioner.
6. Re-install the feed sprocket, moving the feed roller as necessary to align the spindle key with the sprocket (which is constrained by the chain).
7. Turn on the planer and make sure everything is lined up and the feed rollers are moving nicely.
8. Replace the cover
