I had the same problem with the clock on my '84 300D all last winter and again this fall.
Replacing the capacitors did the trick. The instructions mentioned above were enormously helpful. A very handy tool for this procedure is a solder sucker or some other solder removal tool, which helps removing the old caps without overheating the printed circuitry. Phil

That seems very promising. I will plan on doing that sometime in the near future. I would like to get the clock working. The PO before me said it hasn't worked for a while and that MB wants a lot of money to fix it. If I can repair the clock with stuff I have laying around the house... that would be great!

Scroll down the page and it has the capacitor number. My clock worked on the bench and I can hear it clicking in the dash after replacing them, but it still does not keep time. I'll try cleaning the mechanism like was mentioned above. John

Another wrench in the works:
Mine keeps time to a range something better than a minute per month - provided I don't touch it. Anytime I reset the time (DST, etc) it won't restart itself. I have to set it anywhere from 15 to 20 times before it starts to run again. Have wiggled the adjuster, pounded the dash, fiddled with everything that can be fiddled with... and once you twist the minute hand around to some new setting, it almost never restarts. When it does restart, it keeps it perfectly... ?!?

Clock fixed but now speedometer intermittent
Thanks for the link. I guess I got lucky - mine works and I could not see a + or - on the Radio Shack parts. They are also a different color now but same part number. Put it all back together and the clock works - but the speedometer doesn't. Didn't do anything to it except paint the pointer. Odometer and trip meter work so I guess the cable is connected correctly. Is the speed part actually electronic? There is a black box on the back that with two prongs that connect to an electrical wire. If I hit the dash, it will start working.
Suggestions?

My 300SD did that. I believe the setting mechanism was not disengaging. Cured it with some lubrication. I know you are currently at school. If you want to bring it over here (Sparta), I'll be happy to help you with it. Figure 1.25 hr drive from Boone. -Scott
