One of the few non-working parts on my '74 412 is the clock. Has anyone ever successfully fixed one? I took it out, checked the power supply (OK) but I didn't want to split open the actual clock. Is there some way to manually wind it so that the electric winder will start working? Thanks for your expertise!

Just a thought..... you could try taking it to a watchmaker / clock repairer and see if they can do anything...

Hi' there...

I have repaired a couple of type 3 clocks and they have the same movement as the type 4.
The clocks have a " fuse " inside made of a low temp solder material.
When the clockwork gets old the mechanism begins to jam = drawing more amps. until the " fuse " gets so hot it disconnects.

You can remove the rear white cover, clean out the mechanism with compressed air and add a little spray of watchsmakersoil.
Then you resolder the " fuse " with normal temp. solder and the clock it ready to TICK again.
The old " fuse " spot dosen't work as intended anymore, but you can insert a new fuse in the power supply wire instead.

Regards.

That is correct about the fuse. It stays warm all the time. In hot areas...like Texas...the added heat blows the fuse every time. It blows at something like 150 F. Just wire around it. The clock itself rarely needs repair unless it got dusty or rusted. You can also use the later quartz clock in place of the mechanical. Either swap (carefully) base plates...or notch the quratz one to fit with a dremel and a file. Ray

Thanks gentlemen! I resoldered the 'thermolink' and put it back together, and it worked! For a while. Then it quit again, so I'll have to take it out and I think I will take Ray's suggestion and wire around it, and add a fuse as Aulph(?) suggested. I really appreciate this forum and all the knowledge available out there!

Sorry, I meant to say MchAlf!

I just did this job myself, replaced the nonworking quartz clock in a 412 with the earlier mechanical movement from a second clock pod--the one that has individual idiot lights for each turn signal. Had to make holes in the baseplate with a drill and dremel so the mechanical clock would slip in and engage the clock hands. The arrangement works but won't keep accurate time! Can't figure out why...
