This is a project for a friend....circa 1980 Japanese replica of a European wall clock...runs well for 30 seconds then I can see the pendelum falter slightly then it slows to a stop. Repeats itself consistently.

I don't think it was ever cleaned. The bushings (pivots?) had black crystalized old lube in them. Tried to clean them the best I could and
re-oil.

What's next? Thanks in advance for helping.

64 i think you have the answer.Dissasemble clean and oil.That way you have eliminated many possibilities of why it wont run.

If you can see the pendulum falter, I'd suspect a problem with the escapement. Perhaps the anchor is hitting a tooth. Can you provide pictures?

Take a close look at the escape wheel and also on the pallets, looking for excessive wear, bent or worn cogs, etc.

I think Veritas has the right idea. Troubleshooting a clean movement is a lot easier than troubleshooting a dirty one, especially if you carry out a close inspection of all parts as you disassemble the movement, and after cleaning.

First thing I do is check the beat.

Lean your clock till she ticks with pride, then adjust her crutch to that high side.

Thank you all very much. I was looking for crud in the bushings but after reading Bangster's beat balance 101, I went to the crutch and that was it. A little straightening and she runs non-stop and in beat balance.

This is a fantastic website !

Thank you all again.

Never been able to learn Arjay that "lean" is an intransitive verb. Its transitive counterpart is "tilt".

It may be running now but if you wish to run the clock all the time.It should be properly cleaned.Running it this way will just make more wear.
Just trying to state what may happen.:)
