French AD Mougin Statue Clock
In for repair is a time and strike AD Mougin French clock. The repair symptoms include the clock stops and the strike is flat.
A closeup of the makers stamp:
AD Mougin was a well-known French clock maker working in the mid nineteenth century.
He is known to have made clocks in the French clock making region of Montbeliard (which is close to the Swiss border) and is also listed as having premises on the Rue de Turenne in Paris.
He won two gold medals at exhibitions for his clocks and used these as the basis for his trademark which contain the ‘Deux Medailles’ . This trademark can usually be found stamped on the back of his clocks. An interesting link on dating these clock can be found <<here>>
The clock was setup and observed for a while. This was done to observe what the clock was doing and more importantly not doing. Both repair reports were confirmed. The movement was removed from the case and some the external levers and gears were removed. Here is a short video on some loose pivot holes. These two images below show which holes need rebuilding.

In the next few images I want ot show how dirty this clock was. It appears it has not been serviced in a very long time.
Green lub on the mainspring holes
Crud (excuse my "French") in the mainspring barrels
and another one showing oil in barrels
Now for the mainspring ends. Here are two images with massive amounts of green crud

Above I had a link to a short video showing the pivot hole wear. This video demonstrates the 4th wheel on the time side after the new bushing was installed and sized.
These two images demonstrate the before and after pictures of the movement. This first one is taken before the movement was ultrasonically cleaned
and after
A big difference. This movement is over 160 years old and does not look a day overy 20!
As stated the movement was ultrasonically cleaned in hi-grade clock cleaning solution. The movement was then put back together and tested. The mainsprings were put back into the barrels and lubricated with hi-grade synthetic oil. Both time and strike train wheels were assembled. Extreme care is always taken when putting movements back together. This is especially the case with French clocks. The pivots are tiny and hardened. They can break very easy.
The movement was then placed on the test stand and ran for 24 hours. All good so far. At this time the strike train levers and cams were installed. These were tested perfectly. The next step is to lub the movement with again hi-grade clock oil. Here is a short video showing the movement running on the test stand.
