Grandfather Clock Chime is off by a Quarter Hour

If your clock is new or has been recently setup:
Most Quarter hour chime clocks have a self correcting feature. You should wait until a couple of hours go by after hearing this happen with the chimes playing to see if it will automatically correct itself.
If you are turning the chime on / off and listening…it will probably continue to chime the incorrect quarter hour and other strange things until the clock has run at least over an hour.
Again..every time the chime is turned off..then back on, it will probably not play the correct quarter hour chimes until after at least an hour of chimes have played continually. It will correct itself automatically.
If you have had the chimes turned on continuously for over 90 minutes and the quarter hour is still wrong, there is an easy solution.
In a nutshell, what we are going to do is to remove and replace the minute hand where the chimes said it should be, then re-set to the correct time.
1) Wait for the clock to strike the next hour and count the hour. (no matter where the hands are located)
2) Stop your pendulum at this time. (Keep in mind, the clock is right, the hands are wrong)
3) Remove the hand nut in front of the minute hand by turning the nut about a 1/4 turn with a pair of needle nose pliers counterclockwise just enough to loosen, then remove by turning it by hand.
4) Remove the minute hand by pulling it straight out with no left to right movement to the hand.
5) Place the minute hand back pointing to the hour that just struck on the chimes.
6) Re-install the nut by hand, hand tighten while holding the end of the minute hand keeping it from moving.
7) Firming hold the minute hand and tighten with pliers an additional 1/8 – 1/4 turn beyond hand tight.
8) Re-set the time and you are done.
**the time on most clocks may be changed by moving the minute hand backwards (counter-clockwise) until reaching the correct time. *This again will probably cause the quarter hours not to play properly until at least an hour has passed with the chimes playing.
*Continuing to turn the chime lever to on / off will also cause the quarter hours not to play properly until at least an hour has passed with the chimes playing.
Best practice is to either keep your chimes on all the time or keep them off.
Why might this happen?
1) Clock weights go all the way to the bottom and clock stops. (it may not re-sync properly)
2) Moving the chime lever frequently ( short term chime issue until it re-syncs after an hour)
3) Changing the time by moving the Minute hand. ( short term chime issue until it re-syncs after an hour)
4) Winding the clock while chimes are playing. (it may not re-sync properly)
5) Changing the time while chimes are playing. ( short term chime issue until it re-syncs after an hour)
