68 dash clocks

[Hard Charger]

my dash clock does not work.

how can it be tested to see if it needs repair and does it open up to be repaired or cleaned?

$239 for a new clock may be worth it. or maybe an upgrade to a tic toc.

You can open them up but there are a set of points in there which when they contact close a switch to send power to rewind the works.  In nearly all cases what happens over time is the points burn and weld together as the shaft wears the hole into an oblong shape through the center of it all.  Sometimes that can be fixed and sometimes too far gone.

how does it open up, do you need to cut rivets out?

That's what happened to mine.  When I restored my gauges I cleaned up the internals and it worked fine for a while, although it was always a few minutes fast every day.  About a year went by until one day the clock advanced about 5 hours in a matter of minutes and it didn't get any better after that!  

I have the quartz upgrade now but haven't reinstalled the clock.  I wanted to keep the original guts but a clock that is off is pretty useless to me.

No need to cut any rivets.
Has been a while since I did one.The arms pull off,there are tabs for the face plate.
Then three area's that need to be twisted straight to get into the guts of it.
The quartz update is a great idea.Not a difficult thing to do.The instructions were easy to follow.

the quartz upgrade I found says for the TicToc clock only. can't imagine there would be 2 different clocks for the same year car.

They are different.  The tach upgrade doesn't work in a plain clock.

I got mine from Instrument services.If I marked the box correctly ,the clock only kit is # S-3015.
I've done both clock only and clock/tach so confirm the part number before you purchase it.

[Dino]

I can confirm it's S-3015, I still have the box it came in.
