![]() Junghans front plate new count wheel bushing The largest one, which I did not include in my initial assessment, was a 4.5mm (OD) bushing for the count wheel. Seven bushings were installed, 3 on the time side, and 4 on the strike side. Besides, I wanted to place the clock in a prominent area of the house and by addressing wear issues now the clock would run well for some time without another servicing. However, after much thought, I decided there is enough lateral movement of the pivots in their holes to affect its running. I installed all the wheels and checked for pivot movement within their respective pivot holes. I could see that some bushings may be required, 4 on the backplate where there is more load on the wheels and 2 on the front plate for a total of 6, 2 on the strike side, and 4 on the time side but I will make a final decision once I have checked the entire movement further. The only punch mark I observed was just below the escape wheel outside the plate where an attempt was made to close the hole.Īfter cleaning the movement, pegging the holes, and polishing the pivots the next step is deciding whether or not to bush the movement. There has been no bushing work done on the movement. ![]() As always the ultrasonic cleaner does a great job with lantern pinions and the lantern pinions, on all 6 wheels, are in excellent condition. I use a screwdriver to point out any washer I find on a movementĪll parts were cleaned in the ultrasonic cleaner which removed a considerable amount of accumulated grime. Had the pivot been punched in an attempt to enlarge it, had someone hammered the pivot end for whatever reason, had the pivot been replaced or it is possible that the plates had never been separated and that is how it came from the factory? Once the pivot was pried from the plate I rounded the end with a file and it now fits perfectly. By “stuck” I mean that although the wheel was moving freely the end of the pivot had been flattened. I discovered that the motion works centre arbour pivot was “stuck” in the backplate. I had to remove all four pillars (secured by screws on both ends) to determine what was sticking. ![]() Separating the plates was more difficult than it should have been. The crutch has been bent in several places in an attempt to adjust the beat but otherwise, everything looks reasonably good for the age of the clock. After assessing the movement I could see that there had been no significant repairs in the past. The mainsprings are in good condition and there is plenty of power though there is more oil than necessary within the barrels. There are two possible reasons, one that the strike side mainspring was replaced at some point in the clock’s life, or two, there is more load on the strike side requiring a stronger spring. I did not measure the mainsprings but the strike side spring is notably longer than the time side. There is an “S” mark on the strike side barrel cap, helpful when returning the barrels to their correct location. The movement has been serviced at least once, so far as I can determine. The movement exudes quality with solid front and back plates though lantern pinions are favoured over cut pinions. Junghans’s movements are a cut above Mauthe, Hermle, HAC, and other mass-produced German clocks made during this period, in my view. I have heard stories of Junghans clocks from this era running well despite being very worn. Early Junghans movements were robust and strong runners. Junghans time and strike movement, B11 is under the Junghans trademark Move the gong assembly aside (or take it out completely by releasing a screw on the bottom of the case) and remove the works. Open the rear access door to release two thumbscrews screws underneath the movement seat board. To remove the movement remove the hands, first the minute and then the hour hand. This refers to the approximate date of manufacture, the latter part of 1911. The movement is has a maker’s mark with B11 just below it. In any event, my plan was to service the movement. The seller says he had had the clock for two years and never had it running so I was sure it needed a good cleaning. The movement ran briefly after I got it home but after a short while refused to run despite adjustments. The Regency style veneered mahogany case of this Junghans time and strike bracket clock is in reasonably good shape save for a small piece of veneer missing on the front right corner and replacement chrome feet which look decidedly out of place. I posted the first lookat this clock a while back. Junghans bracket style clock, tilted to adjust the beat
