Clock repair

71T Targa · 03-25-2003, 05:59 AM

Well, I finally decided to bite the bullet and try to fix my ailing clock. This hasn’t work from day one of car ownership and I really expected it was toast. It wasn’t, it only needed the solder ‘fuse’ re-soldered. Following the Tech Article, it was really quite easy. The hardest part (emotionally) was breaking the plastic piece that covered one of the nuts. I had to convince myself that I should just snap that off.

Now however, the clock runs quite slow. It has lost about 15 minutes in 8 hours. I’ve been adjusting the screw in the back and I think that may be helping, but how much should I have to turn it? I’ve already gone @2 turns. The inside of the clock was spotless, but should I get a little 3 in 1 oil or something in there? Thoughts?

It probably needs to have the old, coagulated lubricant cleaned out & then re oiled for another 30 years running...;-)

I was thinking that too. What should I use?

Do search here on "Clock Repair". I believe that somebody posted a step by step proc for this a few months back.
I have replaced the fuse myself, and have cleaned and re oiled an older clock, but I do not honestly recall what I used at the time,sorry...;-)

I've had a difficult time finding some low temp solder as per recommendation. My solution was to use some smooth, unwaxed, nylon dental floss to tie the parts that are supposed to be soldered. No wax therefore no drip/mess. I figure that a thin nylon thread will have a melting point somewhere low enough that it will still act like a fuse, just like low temp solder. It's been ab. six months and still going.

Has anyone replaced the clock with a different gauge of some type. I never have had any consistent accuracy with any clock and I'm tired of resetting it.

I am part way into swapping out my clock for a cylinder head temperature gauge... I believe a few others have done the same.

I asked around for the low temp solder (256 degrees ?) Nobody know anything about it. Read somewhere somebody had soldered the contacts together with hi temp solder & installed a fuse in line to handle an overload.

I just replaced the spring driven clock in my '73S with a quartz clock from a 930. Fits perfect, runs like a dream.

15 minutes over 8 hours isn't good. You'll be seriously late for appointments TOMORROW!

I'd ditch it in favor of a quartz movement as Jay suggests.

you can send to PA speedo (or no. hollwood speedo) if you want to drop ~ $150. the clock needs to be cleaned. my local clock shop does these for me ~ $20. if you need dial parts, bezel, etc. you're stuck w/ one of the authorized service stations. (read; PA speedo)
