Clock Repair Help!!!

[luxy1205]

If anybody knows anything about repairing clocks, please help!!!! We are novice clock smiths! I know the clock doesn't work at all, no function at all, but it does move, nothing frozen. I though it was a Telechron clock, but Telechron puts its name on everything and there's no name on the clock. Plus I have a 1952 Zenith "Owl Eye" and it has the exact same clock, just a different color and settings are a little bit different. I'm thinking it's not a Telechron because I don't believe Zenith used them. Help me with any tricks or hints or anything! -Michelle

Nice looking clock radio, Michelle! Have you tested the field winding? If I'm not mistaking, generally a good field winding would read around 5858 ohms, or somewhere pretty much close to that area. If all the gears move freely with ease, it's most likely not mechanical.

I repair clocks

I've repaired these before. The problem that I run into a lot with these is that the motor seizes up so that the clock isn't able to run. The solution is to take sewing machine oil or some small machine oil and apply it to the bearing of the motor. You probably already knew some of this but I'm just trying give you some useful information incase you didn't.

The "old timers" use to do this: They would remove the motor and magnetic field laminations from the rear of the clock. The sealed unit was separated from the field, and its drive shaft area cleaned of all its dirt and grime. Then they would put it into a preheated oven at 250 degrees for fifteen minutes. Immediately upon its removal from the oven, place several drops of light machine oil, like M-10, a quality gun oil at the shaft where it exits the bushing. If it was a Telechron, it would have a circular dam around the bushing retains oil. Heating the motor causes a slight vacuum to appear when it cools - enough vacuum to pull the oil inside. After cooling, the motor should be placed in many different positions for several hours to allow the oil to work its way through the gear works. If you should only experience a slight improvement, repeat the heating-oiling-distribution sequence.

See link. Reply #19 may help you. Also check coil on laminate field for continunity where power supply is soldered on. You should get a resistance reading in ohms. 0 ohms or infinite means the coil is no good. Pretty much like above reply.[this post was last edited: 12/9/2014-04:29]

What did you do to fix the motor?

Could you tell us what you had to fix on the motor?
