How do I install the mechanical clock movement?
When you get the new unit, you may or may not have orange clips over the plastic cable drum covers. These are so the cable underneath the cover will not jump over itself, and get all tangled up. They are on with just a friction fit and just pull off of each cable drum.
Put movement on the seat board with the cables hanging down in between the seat board as it was before. Screw the screws in and make it finger tight and then a little more with a flat screw driver.
