Thanks, Dick. When I serviced the movement, I noted no wear in the pivots. However, the fork was out of alignment/bent so I did my best to realign it. Should I have another go at that before disassembling the movement? Thanks.Hello Rod,
Those floating balances are normally trouble free.
The movements carrying those have been out and in use long enough to wear to the point that dependable operation is no longer possible without serious service.
Many times, problems with escapements of all types are, in reality, problems with power to the escapement. That puts the escapement as being a victim rather than a cause of problems.
More than likely, the situation you have is caused by wear in the movement.
I would suggest you re evaluate the movement for wear to insure proper service.
Hi Dick. Thanks for all your feedback re this movement. It has been very helpful. When I have time, I will disassemble the movement again and have a closer look for wear in it. I never "punch" worn holes. I always cut in new bushings. Rod.My experience is that many problems with these escapements are caused by someone trying to "adjust."
The primary cause of poor performance of floating balances is lack of power due to wear due to long use.
Once someone has "adjusted" the escapement there are usually two things wrong with the clock.
The first being low power and the second being the consequences of adjustment.
The operation of a clock movement is a series of things that must happen.
Having two things wrong with a clock is more than twice as difficult to solve than one.
Proper trouble shooting is of utmost importance and clock repair should not be a series of guesses.
Thanks for this, Willie. All responses tell me to reassess the time train for wear. When I have time, I will do that. Rod."No wear at the pivots", in a pre 1988 Hermle this would be very rare. I just inspected one from1986 (today) and it needs 15 bushings. Willie X
Hi Dick, Sorry to be so long replying. I have had too many projects. I did find a number of worn holes and have rebushed them The clock still loses about 1-2 min/day. The floating balance has a strong rotation and a strong "snap" when running. I note some folks remove weights to speed up the clock. One other site recommended slightly bending the forks to increase the speed. I am afraid to try either. Any suggestions? Rod.Hi Dick. Thanks for all your feedback re this movement.

Hi Willie, I have rebushed a number of the holes and have the time movement only running on my stand. It still loses 1-2 min/day. The floating balance has a good strong rotation and snap as the clock runs. One site suggested to remove a weight from the balance to speed it up. Another suggested I bend the forks on the bottom of the balance frame. I am afraid to try either. Any suggestions? Thanks, Rod.Thanks for this, Willie. All responses tell me to reassess the time train for wear. When I have time, I will do that. Rod.
