Assembling and Adjusting a Count Wheel Based Hubert Herr Cuckoo Clock
HTML-код
- Опубликовано: 30 июл 2019
- Now that I've disassembled and cleaned this old Hubert Herr cuckoo clock movement, in this video I assemble the movement, and adjust the warning wheel position and the strike train great wheel position.
I adjust the warning wheel position so that the movement stops striking. A poorly-adjusted warning wheel will allow the clock to strike more hours than the current time, or to never stop striking.
I adjust the strike train great wheel position - which on newer cuckoo clocks would be the star wheel position - so that the clock stops striking at the end of a gong-coo-coo sequence. A poorly-adjusted wheel will either play the wrong sequence (for example, "coo-gong-coo") or will stop striking entirely.
It's a long video because you see me assemble and adjust this clock movement in real time. Most clock repair videos don't show this assembly or these adjustments, because those steps can involve tedious trial and error (as you will see!)
The clock movement is stamped "21", "Hubert Herr", "Triberg", and "Germany". I found a description of a similar movement to this one, including a catalog picture, at: mb.nawcc.org/threads/cuckoo-c.... That catalog listing is from 1957.

i realize I'm pretty randomly asking but does anyone know a good website to watch newly released series online?
@Finnley Kye i would suggest flixzone. You can find it by googling :)
@Sincere Ace yea, have been watching on FlixZone for since march myself =)
@Sincere Ace Thank you, I went there and it seems to work :) I appreciate it!
@Finnley Kye glad I could help xD
I will be using this video to do maintenance on my cuckoo clock. It doesn't have any markings on it but, it looks just like the one you are assembling. Thank you for this informative video.
This has really helped me, I've been searching for what kind of clock I have and the Hubert Hurr is a perfect match as mine has no markings on it. Plus being my first restoration and a few missing parts you showed me what was missing and how to assemble ! Thank you for posting as mine is 90 years old and still trying to get the minute hand to move.
I use an alligator clip to hold the warning wheel in position in relation to where I want the pin while assembling. Love your videos. I learn a lot.
Hmmm, interesting Thx man... :D
Very well done. Thanks
Perfeito grato pela grande aula parabéns
Great , great work !
Thank you !
Hey Bradford. You can put in all the levers after you assemble the clock. You have to remove the wire spring that gives tension to the stop arm and the pin that holds the stop arm in position. That will allow you to do it. Then put the spring and pin back in. Hope that helps.
Thanks for the tip!
Nice video. I watched one video where they use puddy to hold the wheels in place until the have the movement together. Then they take the puddy out. Just a thought.
gran video sigue asi estoy aprendiendo bastante muchas gracias
De nada amigo (via Google Translate)
Hello, very interesting video. I have a similar movement, of less good quality (much less thick sides and no indication of the manufacturer on the sides). The working logic will be very useful for the restoration of my movement. Jpl
Gracias 😊
almot the same as mine. hard to find video
These parts look great! What solution do you use in your ultrasonic cleaner?
Thanks for the good question; it pushed me to post my current clock cleaning process and recipes on my blog: needhamia.com/cleaning-a-clock-movement/ I have to say in this case that the movement was already pretty clean when I started, but I've also had good luck cleaning nasty, grubby, rusty movements and cuckoo clock chains.
Can i ask where you got the pivot push pull tool? Thanks for your videos. 😊
Pivot locators are available from clock repair supply houses. In the USA, Timesavers sells one: timesavers.com/i-8948894-8-pivot-locator.html
@@BradfordNeedham thanks!
this is really cool. how did you know where to put each piece? i have an old count wheel movement which is completely unassembled and the springs are unraveled. how would you go about getting the springs back in place, and also every other piece where it should be?
I was lucky enough to start from an assembled clock, and took lots (dozens) of photos before and during disassembly. I'd recommend you look at Don Perry's channel (ruclips.net/user/dperry428), because he shows each step in assembling the clock he's working on - his channel is a good first course in clock repair.
For getting springs back in place, you'll need a few tools: a "let down" key and the right-size chuck (winding chuck) for your clock - they come in sets. A mainspring clamp set (although some people have good luck with strong fence wire). I also strongly recommend a good mainspring winder, such as timesavers.com/i-8944167-ollie-baker-style-spring-winder.html. It's expensive, but much cheaper than a trip to the emergency room. See my video, ruclips.net/video/UyIZOXDcTxc/видео.html In that video I used a cheap winder, and the spring almost got away from me.
I have a Hubert Herr movement in a clock, that I would like to dismantle, clean and reassemble. How is it possible to take it all apart and get it back exactly right, without 30 years experience? I can take loads of photos but often more than one part comes away and it is not clear where it goes back. Also from the video, it seems that very small changes to the positions of the gear wheels will make a big difference as to how the clock will eventually function. Howard
Great question!
Surprisingly, I've been learning clock repair only since 2018, and have worked on less than a dozen clocks. The main skills you need are to be methodical (like taking lots of photos) and patient (you'll probably need to reassemble the clock several times). I learned a whole lot watching @dperry428 (ruclips.net/user/dperry428), who shows and explains repairs in detail; his videos are like a master class in clock repair. I also learned a lot from an old video showing how to clean a clock without an ultrasonic cleaner - it does a really good job of showing what you can do with only a few tools and no ultrasonic cleaner: ruclips.net/video/dqlftVki_Sk/видео.html I also learned a lot from just a couple really good clock repair books: Clock Repair Basics By Steven Conover (timesavers.com/i-8944876-clock-repair-basics-by-steven-conover.html), and Striking Clock Repair Guide By Steven Conover (timesavers.com/i-8944875-striking-clock-repair-guide-by-steven-conover.html).
I sympathize with your comment that small changes to the gears' positions make a big difference in the striking of the clock. The main skill you need for adjusting a cuckoo is patience: to adjust the wheel (gear) positions you'll often need to disassemble the clock a little, adjust the gear positions, reassemble, find it's not quite right, do it all again, find it's not right again, and do it once more. When I started learned clock repair I was really intimidated by the process of reassembling a clock; now I still find it time-consuming, but I no longer avoid totally disassembling a clock when I find something isn't quite correctly in place.
Good luck on your clock repair journey, and let me know how it goes!
One small question..I have the same clock, and upon assembly I found that the bird spring had very little tension. I gave it another wrap around, as you did, yet it spins on the metal rod. Is there a small hole in the rod that one end of the spring is attached to? I can’t seem to find one, yet I know the spring must be attached at some point to the rod.could you elaborate. Thanks and you’ve helped me enormously.
From the photos I took, I can see how the helper spring is attached to the bird perch: there is a lever at the bottom of the perch. That lever is pulled in by a long vertical lever to make the bird come out. The bottom of the helper spring is wrapped around that lever a few turns before being wrapped around the vertical part of the bird perch.
I've seen this type of spring attachment in cuckoo hammers as well: the helper spring wraps around a lever part of the hammer before winding around the hammer.
Born Again Clocks has a nice video on making helper springs. In part of the video, he winds a helper spring around a lever in the way I just described. ruclips.net/video/Vx42YH3xvQI/видео.html
46:58 How did you get the pin out to remove the small gear in the first place? I have a similar (but simpler) looking movement, that I can't find ANY info on. Great vid and camera work! Cheers!
There are two ways I've seen and tried: The more common one is to use pliers, with one side pushing on the SMALLER (I originally mistakenly said "larger") end of the tapered pin and the other side of the pliers just off of the other side of the pin - this way you can gently push the pin out enough to grab it with tweezers. The second method, to use if the pin is too short to push, is to use another tapered pin to drive out the original tapered pin, making sure to drive at the narrow, smaller end of the pin (so the pin comes out instead of wedging more firmly into the gear).
Good luck and let me know how it goes.
@dperry428 has a video of him disassembling, cleaning, repairing, reassembling, and testing a clock that has a very similar movement in it. ruclips.net/video/ZeN07SW6Dd8/видео.html He has videos of him repairing a number of different styles of clock, so you might find your type in his videos somewhere - he's very experienced.
@@BradfordNeedham Thanks so much. I've been all over that little gear with magnifying glass...I can't find a pin. Could it be friction fit?!?
@@BradfordNeedham Wow! Thanks very much for taking the time to find this for me. It's VERY much appreciated. Cheers!
@@mustangk62 Cuckoo clocks often friction fit the little gear that's on the minute wheel (the one in the center of the movement, with a long shaft). I try to avoid removing friction fit gears because 1) it's difficult to remove and re-fit the gear without damaging the movement - you need a pry bar set and a staking set, and 2) sometimes the gear is put on in a particular orientation, and it's difficult to put it back on in the correct orientation. Also, sometimes there's a way to free the shaft for cleaning by removing some other part that is pinned on the other end of the shaft. I don't have enough experience to advise you further on that - you might try contacting dperry428 on RUclips. Good luck.
Did you do bushings on this? The wheels seem really loose on this.
It could probably do with a few new bushings. Bushing is next on my "to learn" list. I even have a really beat up cuckoo movement to practice on (after I practice on a sheet of brass).

What is the purpose of the fan in a clock?
It slows down the striking mechanism
@@jordanbusby6231 It also acts as a 'shock absorber' so the striking train doesn't 'slam' to an abrupt stop....that is why you should never solder the fan to its arbor....

Don't worry, sir. Majak cockoo clock(soviet one) is more tricky to assemble then this german one .. German cockoo clocks are made much better(i mean material quality) then soviet one. Every lever is pretty easy to bend. When I assembled mine Majak cockoo i exprienced the problem with 30 minute striking (insted half hour it strikes full hour).. I spend many minutes to figure out what's wrong with that soviet peace of crap and I found that the couting lever was bent in upper directiction so it jumps out from couting wheel slot... Most probably i bent it by mistate during assemble process. I have no idea how because i was very very careful but it's Majak so everything is possible... A few months later I cleand german cockoo from early 60s and it worked from first shot.
Congratulations on preserving a bit of history, and thanks for the warning about Soviet clocks. I've had similar problems with other clocks, discovering damage that didn't seem to be there before I disassembled the clock :-)
Would sure love to see you do a video of a SCHATZ cuckoo. Would it be possible to see the process from disassembly , reassembly and adjustments? Don't know why but I kind of love them.
Buongiorno sono Robert Radovani e parlo da Italia.

Come posso aiutarla? (Google Translate)
Buongiorno e grazie..
Ho un cucù che ho lavato, adesso quando inizia a sonare funziona ma non si ferma , scarica tutto la catena.
Grazie
