Re-assemble a Hermel clock chiming train
Posted: Sun Feb 27, 2011 2:08 pm
Hello Bob and fellow repairers.
I am going to strip and service a Hermel eight day Westminster clock movement 340-020. Before I disassemble the movement, as a reference I fully photograph the movements workings.
My question.
I know that French clocks have cogs are marked and these marked cogs must be re-aligned when the movement is re-assembled.
On my Hermel clock movement there are no visible alignment markings. How do I re-assemble the chiming train so that the chiming sequence is correct, do I set the clock to an hour and mark/scribe the chiming train and hammer cam, taking note of the warning pins position before I disassemble the movement. Alternatively Can the chiming sequence be adjusted once the movement is re-assembled? Following your tutorial I keep the movement trains and mainsprings separate, to ensure the correct gears and spring are re-installed in the correct train.
Thank you for an excellent web site. Roger
