*** Unplug the grinder from power supply ***
PLEASE READ THESE NOTES BEFORE YOU BEGIN:
Some parts of this assembly come pre-lubricated with a food-safe lubricant. Take care not to get these parts dirty.
This kit comes with one new metal washer on the side, but if this washer is bent in shipping, save the old washers when disassembling and use them in the new assembly.
DO NOT USE BENT WASHERS.
Baratza recommends removing one shim from under the Sette cone burr after performing this repair. This is because the new 2018 Sette gearbox seats the ring burr lower, and closer to the cone burr. See step 13 in this guide.
1.Remove motor/gearbox assembly from grinder. Please follow this video for assistance in removing the motor/gearbox (S056/S057): https://www.youtube.com/watch?v=Wflgc4dqm6o&feature=youtu.be
2.Once the assembly is out of the grinder, start by removing the top screw connecting the gearbox to the motor mounting plate shown below. There are only two screws holding the gearbox to the motor. The top screw is easy to access, so you may use a Torx bit or the included hex key.

3. Next remove the bottom screw. This screw is more challenging to access. Start by using the hex key. If you are unable to remove it with a hex key, you may need to use pliers to loosen the screw and remove it.
4. Gently pry open each of the four clips holding the gearbox onto the motor mount. Put opposing pressure on the gearbox to help pull it away from the motor. It is easiest to do this with the motor clamped gently in a vise (wrap with a towel to avoid damage to the motor).
Because the bottom two clips are more difficult to access, it is easier to open those first:
