How to install the clock moon dial
- A. Put on the moon gear. If you have a phase of the moon dial, we will need to put the moon gear on from the old unit, to the new unit. Its only on with a set screw and its the gear that is on your old unit, and not the new one, that resides on the same tube as the hour hand. Put on the new unit like it was on the old, same approximate distance down the hands shaft like it was before. This one gear will interface with the gears behind the clock dial, and run the phase of the moon disc.
- B. Put on the Selector Switch. Next find the small steel arm that is about 1 1/2 inches in length with a set screw. This will go on the arm coming out of the clock movements right hand side. That is to say, your right as you face the front of the clock movement there is an arm sticking out the movement. The selector arm gets put on by sliding over that larger arm and secured with the set screw. It may or may not already be mounted on the movement, but if it is not, it only needs to be able to come through the slot at 3 o'clock. This will enable the customer to change the chime to silent.
- C. Dial Installation. The Moon Dial has four posts on the back that lock into the front plate of the movement. Line up the clocks hand shaft to the hole in the center of the dial and then line up the posts with the holes in the movement. There are two ways to secure the dial, one style has locking arms on the back of the front plate of the movement that slide over the end of the dial post to lock it tight. This is if both the dial and the movement are made this way. The other way this is done, there maybe holes in the ends of the dial post feet where an included tapered pin will go through the hole after it's on the movement. Sometimes the dial will be made with the holes in the end of the posts, and sometimes it will just get locked into the movement with the arms.
