Clock Mechanism Cleaning (Do-it-yourself)

1. Remove the adjustment knob (unscrew counter-clockwise), the two side screws holding the “cup,” and the nut on the +12V tab to free the mechanism.
2. Take the back off the clockworks (three screws on stanchions). Careful: the winder mechanism (a white spring holding half the points) is spring-loaded and can unwind.
3. Dress the points with a points file or a thin emery board.
4. Lube only the bearing points (where a gear shaft touches a plate) — use a WD-40 straw to place a tiny dot exactly where you want it (clocks dislike excess oil, which attracts dirt).
5. Rewind the spring (about three wraps) and reassemble.

If the +12V coil tab is broken off, unwrap one turn of the coil to get enough wire to solder to.
