Grandfather Clock Strike Quantity CorrectionThis article will address the German Grandfather Clock Strike Quantity Correction issue. This is where the clock will not strike the correct number of hours. This includes if it is striking any hour for two hours in a row. Also if it is striking more than 12 hours at a time, or even striking forever. The correction does not require the removal of the clock movement. Only the removal of the dial needs to happen. So the movement can sit in the cabinet like always, but the hands and dial need to be off the clock.
Where the issue is
The best way to learn the simple action of the strike count, is to watch the components on the front of the movement when its striking. Just keep the dial off the clock, make it strike by advancing the minute hand, and watch the parts in the front of the movement in action. Grandfather clocks use a rack and snail counting system. This allows for the proper number of strikes to be heard on the hour. The rack is the saw like thing that drops down onto the snail looking thing that is part of the hour hand tube.
If the rack is not connecting to the snail properly, the strike will not strike the proper amount of times. The correction is in the hour hand tube itself. That is the tube that the hour hand mounts to. This tube is one or two teeth off from where it is should be and is an easy fix.
Strike quantity correctionIf the clock is striking the wrong number of hours, some hours or not all, the snail (hour tube) must be turned slightly. This will allow the rack to fall on the snail's humps correctly. The C clip comes off the gear it meshes with, so the hour tube can come up some and over the teeth of the other gear. The goal is to have the snail fall in the center of the hump instead of off to the side. If the clock strikes 12 and 1 o'clock ok, then the rest will be fine.
Strikes forever or not at allIf the rack is getting stuck on anything or if it falls behind the hour tubes "snail", then the clock will strike the same amount of times every time. It could also keep on striking forever or any number beyond 12 times. One of the ways it can fall behind the snail is by changing hands. Since the hour tube has the snail on it, it moves forward upon removing the hour hand. This can cause the rack to fall behind the snail and therefore does no good for counting strikes like it should. The fix is to lift this rack with your finger and push the hour hand tube back so the rack falls on it.
