Good page. I have a similar technique that's worked for me, too, and uses less equipment...<P>Balance the rotor on a lit light bulb (I use 100W), pinion down, for about ten minutes. It'll get nice and hot. Then dunk it into a paper cup filled with enough lightweight petroleum oil (I've used automatic transmission fluid) to cover it completely. Let sit in the oil for a few minutes, then dry off and repeat three or four times. The rotor inhales oil every time it is dunked as it cools. <P>Brought a couple of Telechron clocks back to life for me.<P>Thanks for your time,<BR>Paul<P>------------------<BR>

I've re-oiled a few Telechron rotors, particularly the one in my 1942-ish GE kitchen wall clock that's been working for 60 years. Sucking the oil in past the output shaft would probably have been better than what I did, but my method worked too: filing an edge very thin and then poking a hole through the thin metal. I used a glass syringe to inject some heavy clock oil (bought from Brookstone before they turned into a yuppie toy outlet). Then I soldered the hole shut.<P>------------------<BR>

Hi,<BR> My fast method is to gently drill into the back with a #42 drill bit, when drill appears to be breaking through stop and finish by hand. If you want to flush the insides spray through small drilled hole with cleaner and dry with blow dryer. Some 3-1 oil and solder hole up, done.<BR> Ken<BR><P>------------------<BR>

Dr Radio,<BR>Are these the same movements as the Telechron/GE wall clocks such as the 2H27 or similar?<BR>I am thinking about snagging one from evilbay soon. I need more clocks. <P>Thanks for the information on your website.<P>------------------<BR>

It isn't enough that I have 500+ radios, 11 collector cars, 6000+ records; I also have to like Telechron clocks. They're remarkable because I've had very little (almost no) problems with the rotors. I favor them because they're pure class. Their movements are almost eternally working and their cases are extravagantly made. There are probably 60 Telechrons hereabouts. I have one right now that has given problems, and I'll try one of these ideas out. I like the idea of the Mobil synthetic oil. I would otherwise have used 3 in 1 oil, though I understand that it's also good for these rotors. <P>------------------<BR>

Most of those clocks are trusty old workhorses. Unfortunately, once in a while a cog problem develops within the sealed part. Rare, I know. Darned if I can get in there, and out, and fix anything <P>------------------<BR>terry h

Wow,<P>Glad to see renewed interest in this topic <IMG SRC="http://antiqueradios.com/forums/wink.gif"><P>Davep- Yes GE/Telechron of the same era use the same encapsulated rotors.<P>I would have to agree, the Telechron/GE clocks are just plain classy. They made some very interesting designs.<P>To the people who collect clocks--does anyone have the model that looks like a strange bird with a long beak (the clock is apart of it's "stomach" or the supposed puppy clock I saw on eBay some time ago where the puppy plays with an animated ball somehow connected to the inner mechanicals???<P>Joe<P>------------------<BR><I>Clock-radios, the original form of multi-tasking!</I>

I love the Telechrons too! <P>I only have two at the moment, a 2H07B kitchen clock and a 1F312 office clock, both from 1938.<BR>Both were stripped down to the last gear, cleaned, lubed & repainted and have been running flawlessly for several years.<P>There are at least a couple great Web Sites dedicated to the Telechron.<BR> <A HREF="http://www.frontiernet.net/~mdemeo/" TARGET=_blank>http://www.frontiernet.net/~mdemeo/</A> <BR> <A HREF="http://www.telechron.net/1f3081f312.htm" TARGET=_blank>http://www.telechron.net/1f3081f312.htm</A> <P>BTW did anyone see this beauty: <A HREF="http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3210729376&category=797" TARGET=_blank>http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3210729376&category=797</A> <P>Eric<P>------------------<BR> <A HREF="http://www.vintagetvsets.com" TARGET=_blank>www.vintagetvsets.com</A>

Dr radio or anyone else,<BR>While we are on Electric clocks here, do you or anyone else have ever seen the insides of a Kit Kat Clock? <BR>I'm also interested in one of these<BR> <A HREF="http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2162821514&category=13859" TARGET=_blank>http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2162821514&category=13859</A> <P>"Masterpiece of American Kitch"<P>The values of the working ones are high and the lower priced ones of course say they do not work or is unknown.<BR>Besides maybe a lubrication problem, what else usually happens and is the mechanism (mechanicals besides the movement) easily repaired.<BR>In other words what should i expect to be wrong?<P>Thanks!<P>------------------<BR>

Hi,<BR> I can remember my grandmother had a red cat clock with swinging tail and eyes moved. It was well before 1960, like in the 1940's.<BR> Ken<BR> <P>------------------<BR>

Davep:<BR>The 50's Kit Kats used a WG-500 motor from International Register Co. Their drawback is the first gear right on the motor. It is made of plastic and is a very small 12 tooth gear. It usually disintegrates due to age. I tried to track one of these down a few years ago and nobody carries the motor any more. Your best bet is to find a broken Kit Kat with a good motor or put the newer motor in from a retro Kat. It uses a round synchronous motor and has better gears in it.<P>I have a blue one like the one on Ebay, but it is missing the tail and a lot of rhinestones....<P>------------------<BR>Eric M.

Thankyou for the info and advice Zeeny!<BR>That's what i wanted to know.<BR>So, the 1969 one in the auction is the retro clock?<BR>Happen to know the year they changed the motor and are there identifing numbers?<P>I'd like to bid on a project clock, but i know nothing about them. I take it parts for these are scarce?<P>update edit: There is a website (finally thought to search under Calif Clock Co)<BR>Looks like most things are available, although like you said..no electric motor.<BR>States that electric motors made up to 1980. <A HREF="http://www.kit-cat.com/index.html" TARGET=_blank>http://www.kit-cat.com/index.html</A> <BR> Thanks again.<P> <BR> <P>------------------<BR>

Hi,<BR> I was into the Empire State Telechrons for awhile. Had many browns, a few whites and one lime green one. Motors are a piece of cake, once in awhile the transformers would be bad. Usually the gold trim pieces have fallen off and you have to buy two or three clocks to make one. Not worth doing it for a brown one but the white and green are in demand.<BR> <BR> Ken<P>------------------<BR>

Is that web page now at:

or is there another one?

The "repair" for Telchron motors that I have used for decades came from a tip in one of the electronics publications I read.
It simply to put the motor on a 100 w light bulb till you see a little oil bubbling out the shaft hole.
Then, take it off the light bulb, and as it cools, drip a light machine oil around the shaft hole. As the motor cools, it will suck the oil in around the hole. Be sure to use a hotpad to remove the motor. They do get hot!!

I do think the idea mentioned of submerging the motor would be better; but the method I used could be done on a service call to the customers home. (Yeah, I did home service calls on radios when I was young.)

Placing the rotor between the wires on the Weller style soldering guns seemed like the easiest way to do that as balancing on a hot 100w incandescent (do those still exist?) bulb seems a bit awkward at least for me.

The article that Dr. Radio wrote at:
http://prepostmodern.com/rotors/
did a very good job of describing the procedure.

I place my droplight face up and put the clock rotor on it. The droplight concentrates the heat enough that a 60 wall bulb is plenty hot.
