Can anyoen explain the principal of mechanism of the clock. I have it apart and I see the contacts, when I close them and apply voltage , the contacts arc and pushes the other cotact back. Is the contact spring loaded and supposed to wind back until it reachs the contact again ....??? because thats not happening ?? thanks for response

 

I believe that's how it works, I took mine a part cleaned it as best as I could, lubed it a bit and it ran for a while, then stopped. I sanded the contact areas as well. Once I put it back together completely it never ran, so my plan is a quartz conversion

 

Spray a little WD40 or other light oil in the works. Not enough to run all over everything, just enough to get a little lubricant in there. The WD40 will clean and lubricate the clockworks.

When the points in the clock close, the electrical connection activates a solenoid that "winds" the clock mechanism. That's the "tunk" you hear every couple minutes. As the clock ticks down, the points move back closer together until contact is made again and the cycle starts over. So, it's not actually an "electric" clock so much as it is an electrically wound clock.

A quartz movement OTOH is a fully electric mechanism- it has a motor whose speed is controlled by the oscillations of a quartz crystal.

 

Had the clock in my 1968 Delta converted to quartz this past summer by Bob's Speedometer in Howell Michigan.You would not realize that it's quartz because the second hand does not jump but runs smoothly. I initially saw their ad in Hemmings Classic Car magazine.
Now it keeps perfect time.

i have fixed many clocks this way and held accurate time after i was done.

 

thats what i figured, I actually soldered the contacts and than sanded them evenly , added some sewing oil and she works beautiful so far.......thanks for response Dave


by the way nobody has answerd the question on my 455 engine , should I get rid the the choke heater in the intake or leave it ?? Pros and cons ?? thanks
