Electric advertising clock repair

Moped Lar (OFMC) /

Anyone have experience repairing or replacing electric clock motors? I have a few vintage Coke clocks like this one that have burned out motors. I hate to replace them with those cheap battery powered clock movements. Any ideas or thoughts?

Re: Electric advertising clock repair

You can buy replacements motors on eBay. It’s a pretty easy fix. I went thru a neon clock phase a few years ago.

The problem is that the original electric motors are not attached to the face of the clock, they are mounted to the back plate. Replacement motors are typically mounted to the face of the clock. If I go that route, the movement will be visible when the light is on inside the clock. It’ll look cheesy. That’s my dilemma.

I’ve dealt with timesavers for years. They have good prices on hard to find parts for mechanical clocks. 30 hour, 8 day, anniversary clock parts, etc....

But i do remember a section in their catalog for electric. Maybe search their site for “electric” or “synchronous”.

I just pulled a search on their site for “motor” and got several hits.

Thanks! Now I need to try to match the original motor to something of similar orientation and dimensions. That’s the hard part.

If the winding has continuity, could just be a matter of cleaning and oiling the movement.

Re: Electric advertising clock repair

Was thinking along those lines myself, I LOVE those old clocks, if it's really quiet you can hear them run....a reminder of a much slower, simpler time, I hope you get them fixed up.

Synchron clock motor search should get you started in the right direction.

I do feel your pain Larry...

Very nice vintage pepsi clock! I have a 50’s NOS pepsi clock I’m waiting to hang in my new house in VA when it’s done.

As you can see, it’s not easy to find a motor with the right dimensions and orientation, as well as the same shaft length. I’m gonna try to match it up the best I can.

I had 3 like these. Every 6 seconds the card would flip showing a new advertisement. Ads were all hand painted. I sold them to a dealer about 3 years ago. The one shown is a salesman demo.

Larry, the point of failure on these is almost always the grease inside the gearbox. You have two options, first heat the motor/gearbox assy with a heat gun and plug it in. Around 50% of the time this is enough to get it running again..

Option two is an alcohol soak. You'll start seeing grease seep out and when you do try to move it manually. If it frees up let it dry and drip in some 3 in 1 oil.

Thanks, I’ll give it a shot and report back.

Took apart one of my vintage Coke clocks today. I determined that the clock's motor is ticking away fine, but one of the gears is intermittently not turning. I'm gonna take a look at one of my other Coke clocks and see if I can cannibalize any of the parts to make one good clock out of the two. Fingers crossed.

Well, I dug into my other Coke clock and found that the motor is fine, but the movement is shot. I managed to got a hold of the manufacturer of the original Synchron motor/movement and they said the movement is obsolete. Oh well....

Re: Electric advertising clock repair

Doesn't mean that no replacements exist...

Re: Electric advertising clock repair

There are no direct replacements according to the manufacturer. However, I found a similar electric movement/motor on eBay that I can use with some small mods to the clock. Only $65 and it’’ll be back in business.....I hope.(edited)

First one is done. It’s whisper quiet.

I recently fixed up an old clock from my grandfather, it was a fun and fulilling project!
