Seth Thomas #2 Regulator 77A movement

[Bill Kendrick]

I am trying to get my clock to continue to run, it will run for about a minute before the pendulum no longer turns the gear on the second hand. Is there any special measurements for the pendulum, length? Also on the tension setting where the weight spool is located. I set the tension all the way to get the pendulum to turn the second hand, but it will stop after a short while. Are there any instructions I might obtain to set up the clock?
Sincerely
Bill

Hi

From what you are discribing it could be anything worn bushings, a bent pivot, dirty movement, or simply just out of beat.

Do you know if this clock has been serviced recently? If it has it may be just out of beat. When it is running is it a nice even tick tock? If not, see if you can get it to run crooked on the wall. If you can then it is out of beat. also make sure the pendulum isn't rubbing on part of the case. Make sure the wall it is hanging on is plum.

If it hasn't been serviced, It may need to be. It could be that the movement is either dirty, worn or in most cases both. The worst case is someone has already done some work on it and damaged something. Fortunatly it is a simple movement to work on. I do have a couple a spare parts for a 77a movement if you need any center shaft through escape wheel.

I got the clock from a forclosed house, and have been trying to make it work. I just got all the parts I needed to make everything work. I will try cleaning everything, and to the best of my ability I have tried to make sure all the gears spin freely, insuring the shafts are straight.
Thank you for the information, if I need any of those parts I will let you know.
Sincerely
Bill
