Picture of Urgos Grandfather Clock Movement Parts

By on November 25, 2009

I thought it would be fun to show all the parts of this movement. In the first photo it has been disassembled and is ready for cleaning. You can tell it needs cleaning by the black deposits on the pivots (the ends of the gear shafts that turn in the holes in the brass movement plates). Many of the parts are strung on wires for convenience in cleaning. Parts such as the hands, chains and hammer heads are not put in the cleaning fluid.

This movement plays Westminster chimes on each quarter hour, and strikes the number of each hour after the hour chime. The time gear train is in the center, chiming on the right, and hour striking on the left. A clock that chimes has about twice as many parts as one with just hour and half-hour striking.

Many of the pivots needed polishing to remove wear, and I installed 19 bushings to correct for wear in the pivot holes.

The movement is labeled at the bottom:

Gravely Furn. Co. Inc.
Martinsville, VA USA
Made in Germany
No ()) Jewels
Unadjusted
PL 85 CM

This movement goes to a Ridgeway grandfather clock.

Junghans W202 Clock Movement

By on November 24, 2009

I repaired this Junghans W202 clock movement. It has the numbers 33 3 on the back which may be a date code of March, 1933; does anyone know if this is correct?

The biggest weakness of this movement is that the mainsprings are attached to their barrels by tongues cut out of the barrel wall itself. When I received the movement for repair, the time barrel tongue was broken and had been unsuccessfully repaired. The tongue on the strike mainspring barrel broke as I was winding the spring in after cleaning

I made new steel mainspring hooks, drilled a hole in each barrel, and riveted them in. The slideshow below shows the previous repair on the time mainspring and barrel, one new hook I made and installed, and general views of the movement and dial.

The strike second gear had a gear tooth that about to break off. I inserted a new tooth. The pivots needed polishing, and I also installed several bushings in worn pivot holes.

Repair job 4961.

I want to thank Clockmakers Newsletter for their article on repairing barrel hooks.

1950′s Regula Cuckoo Clock Movement

By on January 10, 2009

I just overhauled a 1950′s cuckoo clock with a Regula 8 day movement.This older movement is different from the modern one, so I am illustrating it here. This movement needed to have the pivots polished and bushings installed. The pivots were not too badly worn, but some appeared to not have been well polished when new.

The case is 18 1/4 inches tall including the top carving; and 15 1/4 inches tall without the top. The overall diameter of the dial is 4 1/4 inches.

The weights are labeled “1500″ and weigh 1545 and 1530 grams. It doesn’t matter which weight goes on which side.

A couple years ago I overhauled my own cuckoo clock with the same movement, that my uncle sent to my parents from Germany in the late 1950′s. It had been unreliable most of its life. The pinion of the time third wheel was very badly worn, so I installed a new pivot, and polished the remaining pivots. It now runs very well.
