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 rebuild even the
aluminum ones.

Any rebuilt Telechron "B" rotor can have any shaft you'd need.  Once I
open up a "B" rotor I can install any configuration of shaft or pinion.

The Telechron rotors that I sell at: http://www.atmosman.com/rotor.html , are the copper
and nickel 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.

	The F has two screw holders built ring into the steel cast.
These "F's" were made during World War II in order to conserve copper.

Information on the Rotor

The type of rotor (B-3, B-2, H-3, etc.),

TOP (This is significant because all rotors are self lubricating and the word TOP
must point straight up for the self lubrication to be its most efficient.)

The "M" # (M-1, M-31, M-38 etc.)

The RPM's of the rotor (RPM),

The current in cycles (CY),

A production number

Coil & Plate Information


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.

If your clock is "humming" and the rotor is not at fault, then your
coil could be oversized for the field.  Meaning that if your coil was replaced
with an oversized coil, then that will produced a hum which some cannot diagnose.

The "plate" over the back of the rotor has all the information you
need. This plate cover contains the following information:


  

    
      

        

          the "type" of rotor needed
          the volts (V)
          the current in cycles (CY)
        

        

          the Model # [either the clock or the movement, not
            sure] (MOV)
          the RPM's of the rotor (RPM)
          the wattage required (W)
        

      

      
All coils cost $150.00 plus the $20.00 shipping (Canada is $45.00), 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.
      


      Any coil of the same wattage will work but the inside diameter is slightly
      different for each and the tightest fitting coil will give the best results. 
      What I'm saying is that if you need a coil and the coil # is not legible then
      you should send the field and old coil and I'll find the best fitting good coil
      and return same.   The cost is the same $150.00 plus shipping.
      


      The 6 watt # 37 coil is extremely rare and only available with the purchase of
      a complete 60 RPM motor.
      


      
To determine whether or not you need a coil, you can take a Multimeter or Volt/Ohm meter,
      these are less than $20.00 at any hardware store, and with no current on the motor, set the meter
      to Ohms and touch the two leads to the end of the wires or the posts where the wires connect and
      see if you get a reading.   Just about any reading is a good one and if you can see the coil #,
      that represents the Ohm reading so if your coil is a # 60 coil then you should get about 60 or 600 ohms
      depending on the setting of the meter.

Payments



    All checks must be made out to Mike Murray because I gave up my business checking.

    I would like payment by money order, certified check, personal check,
business check, or through Pay Pal or Square, which is the only way I take
credit cards.  I do prefer a check over Pay Pal or Square because Pay Pal and
Square take 3%.

    The 3% is added to the total bill if you use a credit card.

    With either Pay Pal or Square, I will send an invoice to your E-mail
address.  Here you are dealing directly with either service and not me.

    You do not have to be a member of Pay Pal or Square in order to issue a payment but
the 3% will be added to your total bill.

	All of the added fees are exactly what either service charges me for taking your
credit card.

You should realize that a Telechron coil will effectively replace the Hammond
with the same wattage considerations.

36 Tooth Pinion for Most "B" Chiming Clocks



Most Herschede, Revere, & Telechron chiming clocks take the "B" rotor
and attached to that rotor is a 36 tooth pinion.   These pinions are lost at a
far too great of a rate.   I have a small stock of these pinions, which are
guaranteed to be an exact replacement or your purchase price will be refunded
to you upon the pinion's return.

All 36 tooth pinions cost $75.00 plus $20.00 priority mail (Canada is $45.00)
and are guaranteed to fit and work properly, which brings your total cost to
$95.00.

If you want to send in the clock for pinion replacement, please be advised that
shipping will jump to $100.00 with everything else staying the same.  The increase
covers return shipping and insurance and includes my labor charge of $100.00 for
the replacement. ($175.00 total)  Shipping may be higher than the $20.00.

    All checks must be made out to Mike Murray because I gave up my business checking.

    I'll not ship the pinion until I received payment.  I accept personal checks,
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!  If you use a personal check then please allow 10 days
before shipping to allow the check to clear.

Fiber (Phenolic) Gears for Most Mastercrafters and Sessions Electrics


Most Mastercrafters and Sessions Electric clocks have a fiber (phenolic) gear,
which is driven by the motor.  These drive gears usually break at far too
great of a rate.  I have a small stock of these gears, which are guaranteed
to be an exact replacement or your purchase price will be refunded to you upon
the pinion's return.

All Fiber gears cost $100.00 plus $20.00 priority mail (Canada is $45.00)
and are guaranteed to fit and work properly, which brings your total cost to
$120.00.

If you want to send in the clock for drive gear replacement, please be advised that
shipping will jump to $100.00 with everything else staying the same.  The increase
covers return shipping and insurance and includes my labor charge of $100.00 for
the replacement. ($220.00 total)  Shipping may be higher than the $20.00.

    All checks must be made out to Mike Murray because I gave up my business checking.

    I'll not ship the drive gear until I received payment.  I accept personal checks,
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!  If you use a personal check then please allow 10 days
before shipping to allow the check to clear.

What if the clock needs more service?


Sometimes the electric clock needs to be overhauled even thought all the electrical
parts are replaced.

Electric clocks and especially chiming electrics, will wear out and rebuilt rotor
or not they will not run or run accurately.  One quick check it to grab the
center of the minute hand with your fingers and see if it wobbles.  Meaning
that there should be a very slight amount of "up, down, or side to side" play.
If the "play" is greater than a mm or so then there is a good chance the movement
will have to be rebuilt in order for the clock to run properly.

If that's the case then please see:

I, Mike Murray, make no claims as to the accuracy or completeness for the
Telechron rotor information.  But I have made every effort to make
sure that the information is accurate.  I was given this information many
years ago and have continually updated for accuracy and completeness.
