Clock repair and troubleshooting

1.28.15 We are not currently using this but it could become something we link to from our FAQ. If we do that, we would want more thorough answers, possibly with pictures or drawings.
Most clock problems can be solved with one of the following:
• Make sure the battery is new and facing the right direction.
• Make sure the clock hands are properly seated on the clock shaft and not catching on each other.
• If the pendulum is not swinging, be sure the pendulum is hung from front to back and that the clock is flush to the wall.
Problem: The hands aren’t moving! 
• If you have a Bike Chain Desk Clock (26f), try re-seating the battery.  In other words, take the battery out and put it back in, making sure it is nicely seated.  If this doesn’t work, replace the battery.
• Are the hands touching?  Sometimes the minute hand can get caught underneath the hour hand, if so you can just move the minute hand back into its normal position.
• Is the battery in and working?
• The center hex nut could be too tight - if your clock is running slowly you can loosen this about a quarter turn.
• If the second hand is not moving, give it a flick it in the right direction.  If it doesn’t start moving again on its own, put the battery in backwards for a few seconds and then return it to normal.
• For non-pendulum wall clocks: is the on/off switch on the back in the “on” position?

Problem: The pendulum isn’t swinging!  I have a Desk Pendulum Clock (26).
Troubleshooting:
• Is the battery inserted correctly?  Is it working?  If your clock is keeping time but the pendulum isn't swinging, you need to replace your battery.
• Is the pendulum centered on the plastic pendulum arm with the weld facing back? If not, center the pendulum on the arm.
• Is the mechanism straight up and down?  
• Is the clock face perpendicular to the desk top? 

Problem: The pendulum isn’t swinging!  I have a Wall Pendulum Clock (26q, 26b, 26a, C2).

Troubleshooting:
• Is the battery inserted correctly?  Is it working?  If your clock is keeping time but the pendulum isn't swinging, you need to replace your battery.

• Is the plastic cover fully attached on the back (covering the battery)?

• Is the pendulum centered on the plastic pendulum arm with the weld facing back?  If not, center the pendulum on the arm.

• Is the hanger pointing to 12 o’clock so that the mechanism is straight up and down?
• Is the clock flush (flat) against the wall so that the pendulum is not touching the mechanism or the wall?



Battery Replacement:
When the clock loses time or stops the battery is usually due for replacement. If your clock uses a button battery, replace it with one of the following types: SR626SW, UCC 377, Ray-O-Vac, RW329 or equivalent


• The battery is accessible from the backside of the clock. Insert a screw driver or blade into the case notch at the side of the back cover and prise open the back cover.

• The battery is retained in position by a tiny metal plate. Move the plate sideways and remove the battery.

• Replace the battery with the positive pole (+) facing outwards making sure that it is retained securely in position by the metal plate.

• Replace the metal plate and the cover by reversing the steps you used to get them off.
