Introduction

The extensive use of a music box and winding the main spring excessively will lead it to fail. This failure is caused because the music box mechanism gets jammed, and then, you are no longer able to enjoy its beautiful tunes.

However, the music box that you have loved and cherished over the years can still be salvaged. This guide will help restore your music box to mint condition with some easy-to-do steps that will assist the restoration of the mechanism.

With minimal effort your music box will resume entertaining you with its beautiful tunes.

Tools

Step 1

Use a Phillips #0 screwdriver to unscrew the screws at the base of the music box.
Remove the outer casing and isolate the mechanism.

Step 2

Gently wipe the mechanism with a cloth to get rid of any settled dust particles.
Make sure you wipe all the open and accessible surfaces of the mechanism.
Be extremely careful when cleaning the comb and the drum. The comb is delicate and can break when too much pressure is applied. The threads of the cloth can get stuck in the pins of the drum.

Step 3

Slowly turn the winding key in the opposite direction to release the tension built-up in the spring.

Step 4

Tap the base of the mechanism a few times to release the governor assembly.

Step 5

Gently push the governor fan with your fingertip to assist its spin movement.

Step 6

Use a toothpick to reach the flywheel.
Push the toothpick forward to spin the flywheel and assist its rotation.

Step 7

Using a narrow nozzle, spray some WD-40 on the spring housing gear and the governor.
The nozzle is pointed at the spring housing gear in the first photo, and in the second photo the nozzle is pointed at the governor.
In case you don't have a narrow nozzle, you can add a few drops of WD-40 using any other small quantity dropper.

Step 8

Keep the music box playing for a few minutes after it restarts.

I don"t recommend the instructions above. as they are not careful and can result in more harm than good.

Never wipe your music box with a cloth. Here are my instructions:

- take the movement out of the housing. older ones use flat head screws newer ones cross head.

- remove the comb and place upside down on a soft cloth so as not to break any teeth

- if you cannot remove the governor oil it using a tiny drop of 3in1 oil.

- if you can thoroughly glean and polish governor first with rubbing alcohol and then a little polish.

- reassemble the movement the way it came out.

- play the movement through all the tunes a few times to ensure proper playing.

- once the steps are completed your music box will be done.

Very clear instructions. However my music mechanism has glue keeping it firmly to the base of porcelain box. How to release it so I can follow your instructions to repair it. It's a Lenox figurine of baby sitting & spinning on a Christmas gift. White with gold accents

Thank you

You should be able to loosen the glue with denatured alcohol, acetone or a heat gun, or a hair dryer if you don't have one. Then gently remove the music box. When your finished you can reglue the music box into the figurine with a household glue like E6000.

Mine is in a stuffed animal and i dont want to have to break the plush to fix it

With stuffed animals, use a seam ripper to undo the threads of where the fur is sewn, then sew it back together after the repair

I would add that unless it is a swiss mechanism you would be better off replacing. I do not usually restore these plastic ones.

I have a different issue with a few of my daughters disney snow globe music boxes, she has never played most of them since purchase 10 + yrs ago. We tried a few that she wanted to sell but the music box wouldn't play on them with minimum wind. one had a leak but the others are still in new condition sitting on shelves since purchase with no visible problems except surface dust. Any clues how to fix them.
