I have a Gustav Becker Anniversary clock with serial number 2065461 which I believe dates it at about 1898 -1900.
The clock has been working OK recently but after cleaning, etc and the fitting of a new suspension wire I am having difficulties getting it to run. It runs very well for about 15 minutes and then stops. I believe this is due to the fact that the pendulum is not getting the 'push' from the main spring. Looking at the anchor pin it is very jerky as it moves from side to side and I don't know where this inconsistency is coming from. Also the fork attached to the suspension wire seems to have very little displacement. It would be useful to know just how much displacement is normal (in mm not degrees!).
I should be very grateful if anyone could cast some light on where I should go from here. I'm very reluctant to play around with the pallets, partly because I can't get at them without dismantling the gear train and then I can't observe their operation.
Best regards,
