78 clock removal

[Ken Liperi]

What is the easiest way to remove the clock from the instrument cluster in a 78? It seems impossible to sneak my hand up from behind anywhere. And I imagine those screw heads around each guage are fake huh? I need to replace it with another electro-mechanical clock for NCRS judging this spring. After that, it can stay dead!

The instrument bezel has to be removed in order to access and remove the clock. First, you have to remove the 2 screws which retain the bezel to the console trim plate. Then, you have to remove 4 screws at the upper portion of the bezel. Lastly, pull the bezel forward and remove the wires, etc. that prevent full removal of the bezel with attached instruments.

Once the bezel is out, the clock can be easily removed.

And, yes, most of the "socket head screws" on the bezel are just for looks. You can't remove them.

I believe you'll have to remove the side carpeted console panels to reach the two screws on the bottom which secures the top bezel to the console trim panel...as Joe describes. Also that bezel somewhat "tucks" snuggly up into the dash panel so you may have to give it something less than a robust pull to free it from its mooring.

You'll find the backside of the bezel a printed wiring card of sorts and the clock attaches with a nut (as I recall). I sent my clock out for repair and its still ticking and that was over ten years ago.

Ken,
the mechanical clock is a lot more durable than most give it credit. It fails because it has to work 24 hours a day, 7 days a week without maintenance. You would never expect that of any other mechanical device, and especially after 27 years.

All they really need is to have the mechanism cleaned, lubricated, and the electrical points cleaned and it is usually good for several years. This link is for the midyear clocks but it is basically the same information.

You can do this for about $5 yourself or pay someone $100 to do the same.

Ken-

To keep from scratching the shift plate or worse, breaking off a hvac slider knob, loosen the shift plate and pull it back a little. At least place a protective towel over it. When tugging on the bezel be careful at the top-there is a light socket sticking up right in the center that can catch your dash pad and rip it. You might consider replacing all the bulbs while you're "in there". Good luck.

Re: intrument bezel removal

Thank you for all the helpful tips. I've printed them out and I think I will try to clean this clock myself (beats having somebody clean your clock huh?!
