Clock Not Working: 87 911

[86 911 Targa]

^^^^^
Replace the two capacitors.
This might be your "fix".

I've found 911 clocks to be very reliable, shockingly so compared to the norm.

However, my '85 911 clock had decided to only work while driving and die shortly after. I was ready to ship the clock off the North Hollywood or Moma in New Mexico for rebuild.

Around this time, my car battery died, and after replacing, the clock has never missed a minute. Someone on here could probably explain that, but nonetheless, this solved my intermittent running issue.

Possibly worth checking your battery's health. Many other threads point to capacitors.

Far as removal goes, if the rubber gasket has sealed itself to the dash face, most any vinyl protectant around the edges (possibly letting it sit) will loosen the seal enough to twist the clock and remove it.

I put mine at 4:00 (pm) the traditional start time of Le Mans.

Didn't try the soon trick, although that probably would have worked. Instead i used some plastic door panel removal tools from Harbor Freight. (think tiny plastic pry bars) They come in several shapes, and they did the trick nicely. No damage.

I need to get my clock out as well - under the rubber seal? Or does seal stay in the dash hole?

My clock did not work. I opened it up and changed the two capacitors inside. Bought the parts from radio shack several years ago. Anyway, clock has worked perfect for years. Tiny capacitors were just a few dollars . I uses a cheap solder gun . Do a little research on the capacitors and you can find them online.

Pig eye: seal is just a slip on ring so whether the seal sticks to the unit, or sticks to the dash hole it doesn't really matter. For my gauges, 1st removal under my ownership, the seal tended to stick to the unit for the tacho, but stuck in the hole for the clock. Outer surface of seal has ridges that gently grab. Just tilt and twist from front, or push from behind from different angles to work it out slowly. IIRC, I've sometimes gently put my finger tips on the seal lip to pull it with the unit, just don't be so harsh as to tear seal. I uploaded a photo of the back of my spare tach with the seal slid to the back of the unit with about 6mm of the seal hanging off -- so, you can see what the seal looks like.

I did the same...easy fix once you get the speedo opened up. This thread really helped me...911SC Clock Repair with annotated photos

My clock works but not well enough and it's not enough of a issue for me to have it fixed, plus with it not working I am in the moment and not paying attention to time but to the gauges....I also set the clock to 5:00, because it's always 5:00 somewhere....

After 12 years in storage, the one in my 85' 911 does not miss a beat.
