After cleaning and resealing glass to gear ring, Golden Hour runs too fast. Does this mean replace motor?
No, I would not replace the motor. The only scenario for a synchronous clock motor to run fast is if it's being run at a line frequency greater then it was designed for. I think your problem is elsewhere.After cleaning and resealing glass to gear ring, Golden Hour runs too fast. Does this mean replace motor?
Bob - Over 60 years of repair and warranty work on these clocks, more then one competant repairman had to have proof glass and gear ring were not operating as a tight unit causing (sometimes variable) gains in timekeeping, and regardless of what work has already happened in the current repair. As a test, remove the glued retainer ring and glass, mark both with a line in exactly the same place with a Sharpie, reinstall and test. It will become quickly evident if glass and gear ring are operating together or separately, when opened and checked after perhaps twenty four hours. This same test mark can be positioned to tip of minute hand to perform a additional test or verifying dial train operation with the rotating glass, if the mark and minute hand tip separate. As info, I have never had a GH motor assy by any of the motor vendors fail with fast or slow running, only stoppage. Any vendor's motor will have clear markings for intended frequency of operation, which you can easily determine - Best ~Thanks for the "HERE", I found it very interesting. But, the only suggestion for fast running is the sealing of the glass, which I have already done. It is permantly sealed and tight. Worn teeth apparently would cause running slow. My problem is running fast at the rate of 1/2 minute per hour.
