Removing the movement on a Seth Thomas Grandfather clock is a little different than other Grandfather clocks. If you notice on the front of the clock around the clocks face there is a trim piece of wood. This trim piece allows for a smooth transition around the opening of the clocks crown. In order to remove the movement on the Seth Thomas Grandfather clock, you will have to remove the trim piece first. Most Grandfather clocks will have 2 or 4 screws on the front of the trim piece, however on the Seth Thomas Grandfather clocks, there are 4 screws on the back side. I have seen some older models with 6 screws, however, this one has 4.
In order to remove the 4 screws holding the trim piece on you will need to remove the side panels to the grandfather clock by simply pushing up on the top side of the panel, then pushing the bottom inwards, then removing each one on both sides.
If you look on the seat board that the clocks movement sits on, you will see 2 screws on eac side of the seat board.
You will have to remove the 4 screws on the seat board first, prior to removing the trim piece. One you have removed the 4 seat board screws, gently slide the movement along with the seat board towards the back of the clock. Be careful when sliding this piece and make sure you keep the seat board straight as you slide it back. There is nothing holding this unit in place at this point so be careful not to bump the clock.
Now that the seat board is moved to the back, you can locate the 4 screws holding the trim piece in place and remove them. Make sure you hold one hand at the bottom of the trim piece as you unscrew the last of the 4 screws. Once the 4 screws are removed, the trim piece will slide down so you can remove it.
Once the trim piece is out of the way, you can remove the movement, face and seat board through the front of the Grandfather clocks cabinet.
Below is a video on how to clean and re-oil your clocks movement. This video is a general information video and will show you how to clean and re-oil any clock movement. The process for cleaning and re-oiling is basically the same on all clock movement.
