Mechanical to Quartz Floor Clock Conversion Kit

June 25, 2019 9:45 am Published by Leave your thoughts


Finally a mechanical floor clock conversion kit to make it run by a battery instead. This is for the person who has a grandfather or grandmother clock that no longer functions or just tired of winding the clock.

We do have the new mechanical movement to offer but if this is too much money or too much to deal with, we offer this kit instead. The cost is low in comparison and it will save the clock from the trash or the auction.

The price for this kit that is displayed is far below what you would pay if you got each component separate. However if your parts are still good on your existing clock, you do not need all of this. You can get only what you need. You could use your old pendulum and weight shells, and even your own dial if you want to, and only get the movement with hands.


Mechanical to quartz conversion kit.

The dial is customized here before shipping, the gearing for the moon to spin gets removed for the QU40 to back mount right up to it. It will be required for the customer to drill small holes in the corners of the dial and mount it onto the wood frame or the clock dial trim by small wood screws.

The QU40 5/16 post mounts right up to the dial, the QU40 has the best sound in on the market. You would mount the speaker anywhere in the clock case with wood screws.

The Pendulum drive mounts to the back of the clock case, it will swing whatever pendulum you had before or you can buy a new one

You can take the lead out of your current weight shells and hang them up in the air for decoration with some of your old mechanical movements cables or chains.

Steps to Take
  1. Remove the movement by the instructions indicated in that section.
  2. Mount the movement to the dial included per instructions
  3. Mount the heavy duty external pendulum drive to the back of the cabinet
  4. Attach the dial to the wood case as described
  5. If you choose, you can empty the lead from the existing clock weight shells so they are light, use some of the chain from the old unit and pin them up in the cabinet so have the appearance of the weights hanging in there for decoration.
  6. There you have it, a working, great sounding grandfather clock again. The pendulum still swings, the chime is great, do not have to wind it, for a great price.
