I've noticed several "rebuilders" poping up on the Internet and these rebuilders are cheaper. If you look closely they do NOT warranty their work. I have and always have warrantied my work for two full years.

Telechron Rotors by Sequential Numbers All Telechron rotors are no longer in production from ANY source. I have many rotors rebuilt and in stock. Any rotor that is not in my stock, I can have rebuilt even the aluminum ones. The Telechron rotors that I sell at: http://www.atmos-man.com/rotor.html , are the brass and steel rather than the aluminum that were made from the early 1970's. I don't list or sell any 50 cycle rotors. There is a great book on the subject of Telechron/G.E. clock and it's called, "Electrifying Time" by Jim Linz. Please be aware that the procedure described in the book as "New Life into Dead Rotors" is flawed. The reason is that he suggests using lacquer thinner. Lacquer thinner will slowly destroy phenolic wheels, which are employed in all Telechron rotors. The Telechron "B" rotor was in production as early as 1919 and, the "B-3" has the greatest torque followed by the "B-2". The "M" number of the rotor was Telechron's way of identifying the customer and not the rotor. It has some significance in "B" rotors but all 3.6 rpm "H's" have the same torque.

Information on Telechron coils is intended as a user guide because many past repair people just grabbed any coil that they could get there hands on and for longer life of the clock and rotor, you should seriously consider replacing the coil if your is not the proper wattage.
The "plate" over the back of the rotor has all the information you need. This plate cover contains the following information:
All coils cost $100.00 plus the $10.00 shipping (Canada is $20.00), if that is all you order, otherwise the same shipping package can be used if you order the motor/rotor at the same time, so no additional shipping costs are necessary.

You should realize that a Telechron coil will effectively replace the Hammond
All 36 tooth pinions cost $100.00 plus $10.00 priority mail (Canada is $20.00) and are guaranteed to fit and work properly, which brings your total cost to $110.00.
If you want to send in the clock for pinion replacement, please be advised that shipping will jump to $80.00 with everything else staying the same. The increase covers return shipping and insurance and includes my labor charge of $50.00 for the replacement.
I'll not ship the pinion until I received payment, so in order to expedite the transaction please enclose your payment . I ONLY accept money orders, certified checks, or company checks for payment but repeat customers may use personal checks. Normally shipping takes place one week or so after I receive payment and thanks !
