Often, when a clock isn't chiming at the correct time, it's necessary to remove the minute hand and adjust it. This is done when the clock chimes a minute either side of the time it's supposed to chime. The clock is stopped by interrupting the swing of the pendulum, and the time is recorded, the minute hand is removed and the bushing on the back of the hand is adjusted with needle-nose pliers. The bushing allows the minute hand to be reinserted on the clock at a different position on the face---correcting the early or late chiming.

Things you need
- Needle-nose pliers
Determine the correct time to be displayed by the minute hand. This should be the time recorded, plus the adjustment that's made at the bushing.
Slide the minute hand back onto the shaft. Slide it on evenly without forcing anything.
Turn the hand nut finger tight.
Make sure the hand points to the correct position---the recorded time plus the adjustment.
Repeat the bushing adjustment if the hand isn't pointing to the correct time.
Tighten the hand nut with the pliers. Don't over-tighten it.
Start the pendulum. Open the door of the clock, and grasp the pendulum with your right hand. Swing it to the left and let go. The clock should start. Reset the time by moving the minute hand counterclockwise. Don't move the hour hand; it will adjust on its own in sync with the minute hand.
Tips and warnings
- Adjust the bushing by gripping it with the pliers and advancing the hand. Move the hand with your fingers and hold the hand near the pliers to avoid bending the hand. Say the clock chimes at five minutes past the hour and not on the hour---turn the hand back on the bushing.
