All Hour Strikes Perfect Except At 12

[Kiggsia]

I have installed a Linden 7012 mantel clock mechanism in a small cabinet clock housing. I removed one of the strike rods to have a single tone rather than the double bim bam tones. I am thinking that it would be safer to bend the steel strike rod than the strike hammer lever to adjust the gap between hammer & rod. And even though i tried to be careful, gripping the lever with small nosed pliers and bending with another similiar pair, the lever got jammed up inside the strike gearbox. I removed the gear box & refit it all back together. This unjammed the lever, but now at 12 it strikes only twice. All other hours strike properly. I don't know what to look for being off location in the mechanism because only the 12 strike is faulty. I hope i dont have to live with his anomality....

I have now seen a few threads by others with simiiar problems. But the answers to their questions were all in clockspeak which i have almost no understanding of at this point. So i just removed and refit the mechanism clock & strike modules after repositioning the hour gear, hoping to hit on the right alignnent after doing this a few times. The results were just more anomalities in operation but i
figured what have i got to lose, I dont want to use the clock if the striking is off. I gave up with all hours & half hour strikes correct except that hour 12 now gives 11 strikes instead of 12, or 2 as before. I am hoping that someone who is familiar with this specfic movement, for a Linden 7012 bim bam clock, could tell me just whats most likely wrong & how to correct this and please define the technical terms only a clockmaker would be familiar with. I am a general maintenance man by occupation with a novice hobby of seeing what i might be able to do to fix clocks. I know that if a person doesn't know what he's doing he should never do any more than wind a clock, adjust it's pendulum speed or change batteries. But i'm not doing these things for profit, & haven't been otherwise risking ruining anyone else's clock, i am wanting to learn about understanding & fixing clocks.

Jeff,
I have not read of any repair successes on quartz movements nor have I seen any repair books on these. I got close in trying a repair of an older better built one but in the end, I gave up. Now, I just replace them. You have a chance with yours since you created the issue, you know where to look and then it's just a process of elimination to zero in on the problem.

Thanks for reply, my clock just took a turn for the worser, I buggered something up, now won't stop striking & clock itself wont tell time. I bought a previous Linden 7012 at a flea market a year ago and it was the same thing with the strike mechanism, either struck erratic or for very long periods of time. I didnt catch this until after i paid for it. But yesterday I ordered another used 7012 from ebay, the seller claims it works ok. This used one ive been working with came from ebay, was perfect but i started screwing it up bending the strike lever to fit the strike rod when i transplanted the mechansm in the new used clock case. This time I will only bend the strike rod & hope it doesnt loosen from its mounting screw into the iron strike block. You are right, these quartz mechanisms are not made to be serviced the way we can access & adjust the old mechanical mechanisms. And in my tours of flea markets looking at clocks, im sure a lot of the little simple inexpensive quartz mechanisms are there replacing either a faulty striking or Westminster chime quartz mechanism, or maybe a faulty mechanical mechanism considered to be not worth the cost of having it repaired just to have a Westminster chime or bim bam or Cathedral gong, etc.

My 2nd used Linden 7012 mantel clock came but it doesn't strike either. The seller gave me a refund and let me keep the clock. Both the clock and the strike motors work. The clock keeps time but the strike mechanism is not aligned properly. It will steime for a short or long time depending on how I trigger the mechanism but then hangs up & won't strike when the hands are brought to the hour or half hour. This is a bimbam strike on the hour & half hour. I'm hoping that someone reading this thread is familiar with how to properly align the mechanism, not only the snail but also the little levers that contact lobes on the wheels, and all the parts that need to contact other parts correctly. I have wired in a small connector for the strike motor due to repeated disassembly & reassembly of the strike mechanism trying to see how to align it properly.

If your observational skills are good, you may be able to make one work, seeing that you have two.

I've tried that but neither mechanism would work. Like a moron, I failed to take detailed pictures of how the parts were positioned relative to each other before disassembly.

Yes, I've done that a few times now, I have gotten clocks that went silent striking again, like the Linden clock case in this videoclip with a tikround brand quartz bim bam movement from Amazon. It is given to my Great Grandson who designed the replacement dial for it. It does westminster & ave maria also. The single strike also

heard in the beginning of the videoclip is another clock in my bedroom next door that i got at a flea market and replaced the silent movement with a Rythym quartz bimbam movement but removed one of the strike rods so I can hear a single ding marking the hours through the night if i'm lying awake. But I have a defunct 7012 Linden bim bam movement in another Linden clockcase with, I believe, all parts intact , and as a clock repair novice wannabe, I have the challenge of getting the parts realigned properly. This is an enjoyable hobby for me at 75 years of age in the winter when I am waiting for the Lake Erie boating season in Spring.
