Question
Does the whole movement in a grandfather clock have to be replaced rather than repaired every 10 to 15 years?  For example, an Herschede 1964 model #217, described as still running, but needs cleaning - could it possibly need a whole new movement?  It has nine tube chime, does that wear out as well?  Do this type of clock have limited life due to how long it's been running or how old it is?  Since the manufacturer is not in business any longer, are parts available?

Answer
Hi Pat,
    Toward the end of its life, the Herschede Company used movements made by Urgos, a German manufacturer. I don't know if your clock has a Herschede or an Urgos movement. The Herschede movements were very heavily constructed, and if your clock is 9-tubular chime, I suspect it has a Herschede movement. The Herschede movement has main plates that are about 3.5mm thick, while the Urgos plates are about 2mm.
    Urgos movements are generally available for replacement in Herschede clocks, although there may be some movements which are not available.
    Herschede movements are no longer available and, when needed, are overhauled rather than replaced. These are very high grade movements, and overhaul very well.
    Modern grandfather clock movements last an average of about 20 years, although there is much variation in this. Regular lubrication is an important factor in this. True Herschede movements will last much longer with proper maintenance.
    A clock which has not run for long periods may have less wear than one which has run all the time but, like a car, leaving a clock not running for long periods is not good for it. So, both age and use are factors in its lifespan.
    The chime mechanism is part of the clock's movement, so it wears out along with the rest of the movement.
    Overhauling a Herschede movement is not a problem for a  repairer qualified to work on this type of high grade tubular chime movement. Parts are either available, or can be made or repaired.
