Gotta be the spring for pulling the clock points back to the reset position. You shoulda put a ruler next to it for scale.

Oh yeah! Very specific. You do know your clocks. They are pretty cool. I read this website and then opened up some clocks I have.

I manually wound them and none worked at all. First I used DeoxIt D5 (probably the same Radio Shack cleaner they were talking about in that link) and gave them a good wash followed by some compressed air (gently). Two of those started working. I waited for the points to close and checked continuity from red to black on those two and it looked good. So I hooked one up to my bench power supply and set it for 12.6 volts and about 4 amps.

Crank up the volume and you can here the tic toc and the reset. I just got some clock oil today so hopefully I get a better kick and some improvements in operation.

The 3rd one had the broken spring and I got the wire but still waiting on the mandrels. I could probably take one coil from that end and make it into a loop, but I want to try my hand at wrapping a .008" wire.

When I 1st saw the spring I thought it was the spring that pulled the PRNDL back to park when you shifted the lever on the column . ??? Was wrong I didn't know there was a wind up spring in the clocks>> .Great info. Thanks

It is amazing how many springs are in these cars when you start thinking about it. Just to give some scale to this one, as NJSteve suggested, here's a picture with a dime, then the spring, then a 1/16" drill bit that slides inside the spring perfectly, a toothpick and I unrolled a little of the new spring wire and that is the last item on the bottom.



It's a little thicker than the thickest human hair, but not a lot.
