I’m looking for suggestions on what to do about a frozen clock motor, the clock gears all move freely, but the motor mechanism is frozen.

the old grease in it turned hard and bound it up. can you open the case to flush it out?

Try warming it with a heat gun to soften the old grease.

There are electric clock enthusiasts who maintain a interest board to deal with issues like this. I believe that the "capsule" can still be obtained (used but working) via that board. There were at least a couple of different capsule versions so you need to know the correct model number. Some people use a Dremel tool to grind a small opening in the capsule case, dunk the assembly in a light oil bath overnight, fish it out and let it drain, then reinstall. I would imagine that it's important to know where to locate the hole (to avoid damaging internal moving parts): you can probably find a canned "how to" procedure if you poke around Google using the keywords "telechron capsule repair".

Here is a link that shows a how to repair half way down the page.

My way of dealing with these is to go get a short length of clear plastic tubing. I can't recall the size: bring the rotor with you. There's a standard size that will just barely squeeze around the output shaft and make a seal. When you get home fill the clear tube with about 10 drops of 3-in-1 oil. Heat the bottom of the rotor with a soldering iron. Usually when it gets hot you'll see a steady stream of bubbles come peculating up through the oil. Allow that to keep going for a minute or so. Then sit it down and allow it to slowly cool. As it does it will then suck the oil in the tube into the rotor and that will almost always do the trick.

If all else fails, I recommend this supplier of rebuilt parts.

Hi,

There are You Tube videos on lubricating Telechron motors that have frozen or are humming or buzzing. Usually they involve heating the motor and allowing oil to seep in around the shaft as the motor cools.

I've used the heating to draw a light oil into the motor method on at least a dozen motors. I set it shaft side up on a 4" square ceramic tile, put several drops of oil around the gear and then heat until bubbles start coming out. As it cools, it draws the warm oil in. I add a few more drops as the initial drops are drawn in. I've had only 1 motor that this method didn't fix and that one had a serious rattle inside when I shook it. I've gotten two or three clock radios where someone had drilled a hole in the side of the motor and none of them worked. I don't know if they got metal into the motor when drilling the hole or what, but they didn't work. I have a clock radio in my kitchen that has run 24/7 for about 10 years since it was treated with the oil/heating method.

Not sure why this old thread resurfaced, but I actually private messaged the original poster a link to my site. Ironically, I never heard a peep.

Many YouTube videos and other pages are based off of my tutorial which has been on the web for over 15 years...yet others take the credit for the procedural in which I was the first to use synthetic motor oil in rotors in which I started experimenting with back in the 1990s.

Here's my system:

Dr. Radio,

Thanks so much for posting your article on Telechron rotor servicing. I've got several Telechron motors that I'm sure could use some attention. I've got some 0W20 weight Castrol synthetic motor oil that I plan to use.

Tom

I've used your procedure quite a few times with great success. The only thing I did differently is that I found it convieient to heat the rotor on my drop-light rather than my soldering gun.
