## Mechanical Clock Weight Installation

The [weights](https://www.clockworks.com/clock-parts/clock-weights.html) may or may not all weigh the same however they usually do not. It is needed to know what [weights](https://www.clockworks.com/clock-parts/clock-weights.html) goes on what [chain](https://www.clockworks.com/product/clock-chain-by-movement-maker) or cable for most floor clocks in existence. Typically there is differences on the [weights](https://www.clockworks.com/clock-parts/clock-weights.html) from left to right on a mechanical floor clock. This section is referring to post WW2 modern floor clocks of German origin.

### Mechanical clock weight placement

A bathroom scale can let us know if either there is two heavy and one light weights, or two light weights and one heavier. The chime side will always take the heavy [weights](https://www.clockworks.com/clock-parts/clock-weights.html) and the strike side will always take the light [weights](https://www.clockworks.com/clock-parts/clock-weights.html). The middle time train is left to be variable dependent on the [pendulum](https://www.clockworks.com/clock-parts/clock-pendulums.html) bob diameter. The [pendulum bob](https://www.clockworks.com/product/clock-pendulum-bob-for-a-wood-stick) is the round disk at the bottom of the [pendulum](https://www.clockworks.com/clock-parts/clock-pendulums.html). If it is a wide [bob](https://www.clockworks.com/product/mechanical-clock-pendulum-bob) or if the pendulum is heavy for other reasons, it will take more [weight](https://www.clockworks.com/clock-parts/clock-weights.html). If more weight is required on the center time train it will be the same weight as the chime side instead of the strike side.

### Weight Installation - The heavy one

The chime weight will always be the heaviest weight there is for the clock every time. This is the [weight](https://www.clockworks.com/clock-parts/clock-weights.html) that goes on the right while facing the clock. If there is a weight that is heavier than the rest it goes on the chime side. What is meant by chime side is the side that makes the songs go every 15 minutes. If the wrong weight is on this chime side the clock will chime very slow and may stop in mid chime.

### The Variable

The next one is the time train. This is the one that goes in the center of the three weights on the clock. If it is a heavy pendulum or the [bob](https://www.clockworks.com/product/mechanical-clock-pendulum-bob) diameter is larger at 8 1/2 inches or 10 1/2 inches wide, its best with another heavy weight equal to the chime side. There are alot of clocks in the world running with the lighter weight when it should really be heavier and the clock runs fine for 30 years. So its not that big of a deal, but to be correct this is what it calls for. If the pendulum is heavy and the light weight is on there instead of the heavy one, the clock may or may not stop randomly.

### The Light one

The lightest weight if there is one, goes on the left while facing the clock. This is the strike train side and this makes the clock bong out whatever hour it is. If the wrong weight is on this side, it may bong out the hours faster than what is intended. This will not be bad for the movement in anyway, its just what is comfortable to listen too.
