It hasn't worked for years. The pulleys that engage the chains seem jammed

I took it to a clock expert who told me it needed rebuilding and it would
cost me $230.
He says the mechanism is worn and the wheels have slipped out of their

get it working.

My 30 year old school clock stopped working 15 yrs ago and just looked
pretty on the wall (just like yours). Last week, I bought "The Clock Repair
Primer - the Beginners Handbook, by P. Balcomb" from www.klockit.com (they
are within driving distance of me) and now it is working like new. All it
needed was a cleaning and oiling. Now I'm getting up the courage to fix my
wife's grandfather clock. Amazon.com also sells books on beginning clock
repair. Before you tackle any repair, you should be well versed on what to
expect. After reading the book, you may very well decide that having a pro
do it is the way to go.
Look at cleaning and lubricating it. That may be enough to get it going,
but it may not. Mechanical parts do wear out eventually, but sometimes it
is just a minor thing. Worth a shot with the right lube. A clock repairman
told me to give a 2 second spray of WD-40 once a year in the back and that
the mist is enough to keep it lubed.
I do not recommend WD-40 for clocks. WD-40 will both harm the clock and
cause problems later for someone trying to repair the damage. WD-40 contains
a detergent that harms metal pivots over time and is a disaster for the
ultrasonic when trying to clean the clock. I am very surprised that an
experienced clock person would recommend repairing a clock by simply
spraying it with WD-40 unless he wanted the business later.

Amen! About 20 years ago I was lubricating roll-up aluminum awnings,
going through can after can of WD-40. So I bought a gallon can of it
and a spray can to dispense it. The can and sprayer sat unused for a
couple years and the excess WD-40 that had been puddled on the outside
of the lid was sticky, gooey, gummy!!
Notice what the label on the WD-40 can says as to its intended
use--nowhere on the can does it say or imply LUBRICANT! Surprise!
I've disassembled a couple old clocks, cleaned the works, oiled and
reassembled. The last time I did it was in 1970--that one was a
non-running 1924 Seth Thomas school room clock that I found in an
antique store for $40. Used carbon tet to clean the parts (I believe
that's no longer available) and bought a tiny 2 oz. bottle of clock
oil to re-lube it.
Used a flattened length of wire (like a tiny screw driver) to apply
the oil to the bearings and the contact points on the escapement wheel
and arm. Those points are critical--they must be clean and lubed just
the tiniest amount. When they get dirty, the clock won't keep time.
It's been running fine since. I think I've cleaned and reoiled the
escapement twice since (without touching the rest of the works).
The black walnut case was a mess, so I stripped and refinished it--now
I'll never be able to take it on the "Antiques Roadshow." Hey, back
then, who knew?
Unlike the OP's clock, this is a spring powered clock. One must take
care in removing a spring from its "can"--even one that's been allowed
to run down. I used a large hose clamp to retain the spring before
removing it completely from the can.
It was a fairly easy and very interesting project. Nowadays I'd whip
out the digital camera and simply record every step in the
disassembly. Back then I recall I drew numerous sketches as I went!

Clockwork is mechanical gears. Ordinary paint thinner should get rid
of the old grease and oil scum. Like the other said, a film of light
oil should be the best lubricant after you have cleaned up the

My German cuckoo clock stopped, so I took it to a clock shop. They told
me that the clock works were shot, and needed to be replaced for $200. I
could have saved on that by lubricating the mechanism on a regular
basis, but eventually the clockworks will not be reparable. The price
given you was reasonable from my experience.
Our repairman charges about $80 for maintenance, minor repair,
adjustment, and lubrication. Since you indicate that some parts are
worn and will have to be replaced, I think the price quoted is reasonable.
Incidentally, there is a specific oil made for lubricating mechanical
clocks. I don't know the composition, but it is pricey. I seem to
recall it was $5 or $10 for about a quarter teaspoon of it (which has
lasted over ten years now). Your repairman might sell you some, and
what looks like a hypodermic to apply it, if you want to do your own

Perhaps. But to do it right you will need measurement equipment and
machine shop facilities that you may not have access to. If you just
want the fun of trying, go for it..."it ain't rocket science."
