How Grandfather Clocks Work

Grandfather Clock Setup and Installation

Seven easy steps and you are on your way.


Located in the bottom of the shipping carton will be a white styrofoam box. This box contains:
a) a key to fit your Grandfather Clock door,
b) a crank which will be used to wind your Grandfather Clock and,
c) weights which operate the Grandfather Clock movement.
Also, within the shipping carton will be the Grandfather Clock pendulum packaged in a separate cardboard box.
Move the Grandfather Clock close to its final location. 
Access to the Grandfather Clock movement, chimes and cables is made in three possible ways; through the front door(s), through the top side panels (or side doors
on some Grandfather Clocks), or through the back access panel. The top side panels are held from the inside by tape or a plastic clip. The plastic clip may be turned
or tape may be removed permanently. Refer to the General Information section on page 7 for proper instructions to remove and install top side panels.
Open the front door and pull down the cardboard sleeve and remove it.  (See figure 1).  Remove the foam pads from between the chime hammers and chime rods. 

DO NOT REMOVE THE STYROFOAM BLOCKS from above the cable pulleys. This is one of the most critical points in the entire set-up operation.  You can remove the styrofoam blocks AFTER your Grandfather Clock is totally set up and has been operating for at least twelve (12) hours.


Position the Grandfather Clock into its final location. Once in place, your Grandfather Clock cabinet
must be leveled, as the Grandfather Clock may not operate if it is not level. There are four levelers under the cabinet on each corner that can be screwed in (up) or
out (down) to make adjustments. Place a level alongside the Grandfather Clock cabinet from front to back and side to side, adjusting the levelers until level. It may be necessary to periodically check your cabinet after initial set-up, (especially if the Grandfather Clock is on carpet), as it might settle after original leveling. (see figure 2). Ensure Grandfather Clock is positioned square and firm on the floor so that
it will not fall over.



NOTE: To perform the following steps Howard Miller suggests wearing cotton gloves or using a soft cloth when handling parts.

Some pendulums have a colored protective plastic film covering the pendulum disk. Carefully remove this film before hanging the pendulum. To hang the pendulum, locate the pendulum guide through the front door, or
any of the side or back access panel locations. While holding the pendulum guide with one hand, slip the pendulum in through the front door with your other hand. Place the pendulum hook over the pin or through the slot on the pendulum guide, and lower the pendulum until it is hanging securely on the pendulum guide. (See figure 3).


DO NOT REMOVE THE STYROFOAM BLOCKS until after your Grandfather Clock has been operating for at least twenty-four (24) hours. Most Grandfather Clocks use three weights. The bottom of each weight is labeled Left, Center or Right facing the Grandfather Clock. The total weight of each weight is slightly different and each WEIGHT MUST BE INSTALLED IN ITS CORRECT LOCATION FOR THE Grandfather Clock TO OPERATE PROPERLY. Check the weights to ensure that they are tightly assembled. Check to make sure that the cable is in the cable pulley. Hang the weights on the pulleys. (See figure 4).


If your Grandfather Clock has a moving moon dial feature, follow these instructions. To set moon dial, apply slight pressure with your fingers to the front of the moon dial. Rotate the moon dial Clockwise until the moon is directly below #15. (See figure 5). If the moon dial will not rotate, wait 6 hours and try again. Never force the moon dial as it should move easily.  Using an almanac or calendar, determine the date of the last full moon. Count the number of days past the last full moon. Turn the moon dial Clockwise one click for every day past the full moon. The moon dial is now set and will indicate the proper moon phases as long as the Grandfather Clock operates continuously. If the Grandfather Clock stops for more than 24 hours, the moon dial will also stop, and must be reset when the Grandfather Clock is started again.



Full Moon
99% of Full
Mon 8 Jun, 2009moon phase info

You may check this months full Moon date here.

The lunar cycle  is 29 1/2 days as indicated on your clock dial.  These are not the days of the month, but of the lunar cycle. 
Let's say the current date is the 20th of any given month and the last full moon was on the 10th of that same month. 

1)  Rotate the moon dial so the moon is under the 15 on the moon dial. 
2) 10 days have past since the full moon according to the example.
3)  Rotate the moon 10 notches clockwise past the 15 on the dial as 10 days have past since the full moon.
4) Your grandfather clock moon dial has now been set correctly!


6. SETTING TIME (moving the hands) To set the time, move ONLY THE MINUTE HAND counter Clockwise (backwards) until hour and minute hand are at the correct time. (See figure 6). DO NOT MOVE THE HOUR HAND WHEN SETTING THE TIME. The hour hand will move automatically when the minute hand is moved. By moving the minute hand counter Clockwise it is not necessary to wait for the Grandfather Clock to chime as the minute hand passes each quarter hour. (See figure 6). The movement has a self correcting feature which synchronizes the chimes with the time. If after setting the Grandfather Clock on time, it does not chime properly, permit it to operate 2 hours to correct itself.
CAUTION ON MOVEMENTS WITH AUTOMATIC CHIME SEQUENCING: The chime selection lever should not be in the ?Auto? position when moving the hands. Moving the hands in either the Clockwise or counter Clockwise direction while the automatic chime sequencing is in operation could damage the chime mechanism.




Reach through the front door of the Grandfather Clock and place your hand on the side of the pendulum disk. Move the pendulum to the far left of center and release. Let the Grandfather Clock operate a few minutes until the pendulum settles into an even swinging motion. (See figure 7). If your Grandfather Clock gains or looses time after twenty-four (24) hours, see General Information Section to regulate the timekeeping of your Grandfather Clock. After the Grandfather Clock has run for at least twenty-four (24) hours, remove the styrofoam blocks by lifting the blocks straight up until they clear the cable pulley. Then gently push them back, through the cables.
