That's such a useful yet not so obvious tip. Thank you sir!Loud Ticking Quartz Alarm Clock Repair
This describes a quartz alarm clock movement repair that is posted here to avoid losing it in the Clock Repair forum. Several YouTube videos to quiet a noisy quartz clock had inappropriate information such as using petroleum oil on plastic, taking action not needed such as oiling more parts than needed or installing a new conventional or a sweep movement.
The high quality clock, a Sharp Model SPC126 has a large 4-3/8" dia. white face with black hands for good visiblilty, an ascending volume and frequency four stage alarm and a snooze feature, all to make it worth repairing. The clock had an annoyingly loud tick audible for more than 10 feet.
Opening the clock case revealed the proprietary movement's enclosure. Removing the enclosure cover permitted lubricating the armature and first gearwheel plastic pivots with a tiny bit of silicone oil. After assembly the movement was nearly inaudible at a very close distance.
This is addressed to both sections of your post.That's such a useful yet not so obvious tip. Thank you sir!
Hello Les. How did you get on? I am waiting to hear! What an interesting movement. It looks to me as if the there is no rack to count the strikes but I do see a rotary switch with increasing lengths of printed contact. That's very likely to be the equivalent of a mechanical counting wheel with detents that counts out the number of strikes. When it runs and the contact falls off the edge it should stop. The switch that sets it off needs to be found. It will likely be on the minute shaft and operated by a cam. I'll bet if that is so that its in permanent contact making it run all the time.So I have a few new pictures as I progress, I see nothing that causes this malfunction! number 3 front Plate and hour gear, 4 is the time movement 5 flip side of time movement. Since things seem sticky electric cleaner and then clock oil on pivots?
