    I received this cuckoo clock via Fedex yesterday and it was packed/insulated to perfection, so no worries there... movement had been cleaned/oiled and as far as I can tell, there are no obvious issues with it, at least to my novice eye. Hung the weights and it took right off. I manually moved the minute hand to hear the gong and the cuckoo sound on the hour and 1/2 hour. All good. Then I walked away from it and never heard another cuckoo call... and the hands had not moved!:confused: What the heck could be wrong? The seller is reputable and I know the clock was working fine before I got it. I am providing some views of the rear side of the movement. I am hoping a member can scrutinize the photos and maybe detect 'something that is off' with this little 30 hour movement. Many thanks for your expertise!

    Is the nut that holds the hands on tight?

    Hi Peter, Fortunately (or unfortunately), the nut is on nice and secure. Hour hand is tucked on nicely. I swear, I've taken those hands off and put them back on at least 5 times, no luck in getting the hands to move. This should have no effect whatsoever, but I did replace the dial with an exact same size but much nicer/better dial and numerals. Right now, I've taken the hands off just to see if the time weight is actually dropping. Shouldn't the clock cuckoo regardless of whether the hands are on or not on as the pendulum continues to swing back and forth ticking away? I should not allow this to make me crazy, but it is!

    On some movements the hand nut provides friction to the cannon pinion/minute hand tube. If the hands are not moving, the motion works isn't moving. If you can find why the hands are stationary and correct that, I suspect your cuckoo problem will take care of its self.

    Do you have a picture of the motion works? It could something as simple as you are missing a friction washer.

    You need to access the front of the movement. It could be that in shipment the pin holding the reverse minute wheel of the motion work came out, eliminating the tension that allows the motion work to be driven from the center arbor.

    Yes, pictures of the front, please. You can remove the dial (just three small pins hold it on) if you are hesitant to remove the movement from the case. In the mean time, I'll move this to clock repair for more input.

    Hi Jeremy,
    Wow~ Okay, I will get the dial off some time this morning and grab some pics. Need some assistance with determining which is the reverse minute wheel.


    Thanks to all you guys for your help!

    I'll be back....

    As Jeremy said, you need to access the front of the movement and check the tension wheel. Try taking the dial off first to see if you can get to it. Here are two pics of what it should look like. You'll have a tension washer underneath and a flat washer on top with the pin keeping everything together. Also, what side of the hand did you put the large minute hand nut on? front or back?

    Re: What the Heck? Black Forest Cuckoo Clock Ticking PERFECTLY~BUT Hands Will NOT Adv

    I let the clock run all night and time weight dropped naturally, but the chime/cuckoo weight didn't move - hands didn't budge. I popped off my 'replacement' dial this morning. First thing I saw was I think the pin that was referenced by Jeremy. I hung the clock back up, put the hands back on without the dial and put the clock in motion again while I uploaded some pics. Holy cow, the &%# hands are moving and clock cuckooing on its own! The only thing I had done to this clock when I received it was to carefully replace the dial it came with. I realize this will not make any sense, but I'm gonna say it anyway... I used the smallish nails that were already in my replacement/second dial, which were longer than the tack nails in the first dial. Even though the nails are on the far outside perimeter of the dial, is it all possible that one of them was touching the movement and preventing the operation/movement of the hands somehow? I put the second dial back on using the small/shorter tacks. Clock is back up on wall with my dial running like a champ. Maybe just pure luck and I will never truly understand what happened here, but had I not removed that dial at your urging, the clock would be a non-functioning wall ornament. :coolsign: I have uploaded pictures, but for some reason, they seem to disappear when I added the dialogue. Hopefully they'll be there when I hit the reply button. Thanks to everyone for all your help and suggestions!

    Yes, it is entirely possible that one of the nails was touching the movement and keeping the hands from turning. I actually started to write that in my reply earlier but then deleted it because I thought it would most likely stop the hands from moving manually and you wrote that you could turn the hands manually. One of the longer nails (probably at #8) must have been pushing down on the top surface of a gear enough to stop it from turning while the clock was running but not lock it up when you tried to turn the hands manually. Glad you figured it out!!

    It was the requests to remove the dial so you guys could have a looksee at the front of the movement. Not a hard thing to do but there are 2 maple leafs that kind of hinder the removal. But I really dreaded detaching everything to remove the entire movement. The only thing that made me think 'nails' was when I saw just how much longer (only a millimeter or two) they actually were. Just plain luck and that rarely happens when it comes to a fix for my clocks. Thanks again!

    maybe the hand cannon was touching the dial hole, Or another I have seen, a drop of oil made it down to the friction butterfly under the secondary hand gear in the front. It might have dried out enough to allow it to move. :)
