10253 Big Ben

Big Benโ€™s clock mechanism wonโ€™t work if the internal gears are attached too tightly. They need to have some space to move around, so make sure you donโ€™t push these parts in too tightly.

Weโ€™ve updated pages 88 and 185 in the building instructions to help builders put the clock together. You can view page 88 here and page 185 here.
