Steps:

1. Use the Phillips #0 screwdriver to remove six 13 mm screws from the casing.
2. Place the screws in a small container so they don’t get lost.

3. Use a plastic separating tool (or a prying tool) to gently pry apart the top and bottom halves of the driver’s plastic housing.
4. Work slowly around the edges to avoid cracking the plastic or damaging internal clips.

5. Once the casing is open, lift out the printed circuit board (PCB), battery, LED, and existing motor assembly as one unit from inside the housing.
6. Using wire cutters, cut the black and red motor wires where they connect to the motor. (You’ll later re-solder to the new motor.)

7. Strip about ¼ inch (≈ 6 mm) of insulation off the ends of both red and black wires.
8. Make sure the exposed wire is clean (unoxidized) and ready to solder.

9. Before soldering, check that the contacts on the new motor are clean and free from residue.
10. Solder the red wire to the motor’s positive terminal (usually marked with a “+” or a red circle).
11. Solder the black wire to the motor’s negative terminal (or the remaining terminal).
12. Allow the solder joints and motor to cool down fully before proceeding.
13. Solder carefully! Using a hot soldering tool may result in injury!

14. Place the motor, along with the PCB, LED, and battery, back into the plastic housing in the correct orientation.
15. Close the casing halves together, ensuring clips and alignment are correct.
16. Reinsert and tighten the six screws you removed earlier.
17. Finally, test the device to confirm the motor now works.
18. If everything functions, you're done. If not, reopen and re-check your soldering and connections.
