Quartz Clock replacement
I received my quartz clock replacement clock kit today for my 74. I was wondering if anyone had detailed instructions on how to do this and if there was anything I should watch out for.
Any help would be appreciated.

I've done two of 'em - like the others have said, take your time and follow the instructions.
Make sure the clock works before you reinstall it (run it overnight to make sure it keeps time correctly). If you don't have a 12V power supply, just hook the clock directly up to your car's battery.

The only problem I had on my original clock was I didn't realize the setting stem was broken. I rebuilt it, tested it, put it in and went to install my new setting ****, only to find out the threads were broke off. Took the clock out, bought a whole new clock and remounted. Sold the rebuilt one on eBay noting the stem was broke,and got back most of my money. The next guy had a clock with a good stem.

Found a great site that explains taking the clock apart. Also give you some pointers for fixing the original mechanism. It brought my clock back to life! Enjoy!

The clock is the only thing in my 80 model that does not work properly. It is a quartz movement, so I'm figuring it has already been replaced. I can pull the *** and let go of it and it will run sometimes up to 20 seconds. Any information on problems and repair of the Quartz clock movements? Also I was wondering if the clock assembly is the same for other vehicles? I noticed a quartz clock in an 82 suburban and it looks to be sized appropriately and identical on the face... Anyone?
Thanks!

Ran for 5 days and stopped again.
The problem was the contacts were too pitted to work effectively....
Simply not enough material left to make adequate reliable contact to power up the coil which winds up the main spring.
If anyone has succesfully replaced the contacts, I'd like to know how they did it.

I believe by 80 the factory started using quartz. If it says quartz on the face of the clock then that would be my guess. You could probably just buy one of the 60 dollar quartz "retrofit" movements and fix yours that way. I don't know of anyway to fix a quartz movement otherwise. I guess you could try some electronics cleaner on the gears and such. I used something from Advance auto. Red can with a picture of a wire harness terminal on it. Don't get the one with the picture of a starter on it (says its not safe for plastics). If that doesn't bring it back to life, get the replacement unit.
