Telechron "B" "M-1" "M-31" & "M-38" Clock Rotors
My business is rebuilding your original rotor.
The type "B" is the larger rotor which generally turns at the rate of 1 R.P.M.
The "B-2" M-1 is the most difficult rotor to work on, the M-31's is the
original "B-3" and "B-2" M-38 are extremely hard to find and cost the
same to rebuild but $250.00 more than other "B" rotors for replacement.
The M-1 is the original "B-2" rotor and very rare. These rotors
have a hole center in order for the long shaft second hand to be inserted.
The M-31 is the highest torque "B" rotor ever build and why it was
used in most electric Grandfather clock and many chiming mantel clocks.
The M-38 was the most replaced "B-2" rotor and extremely rare.
All "B-2" M-1, "B-3" M-31, & "B-2" M-38 rotors cost $150.00 to rebuild,
plus $20.00 priority mail (Canada is $45.00) and have a 2-year warranty, which brings
your total cost to $170.00 assuming you send the old rotor for rebuilding at time of payment.
Because of the rarity, I must have the exact M-1, M-31, or M-38 rotor or add $250.00.
Here I'd take a used rotor from inventory and overhaul it for a total of $400.00 plus shipping.
My turnaround is 6 to 8 weeks for motor service, 8 to 12 months if the clock is sent
with the motor, or if the movement is overhauled.
All checks must be made out to Mike Murray because I gave up my business checking.
All rotor only service requires prepayment made out to Mike Murray, unless you don't
mind waiting a year.
I no longer offer expedited service.
If you want to send in the clock for motor or rotor replacement, please be advised that
your costs will increase by $205.00 with everything else staying the same. The increase
covers the increase in return shipping and insurance and includes my labor charge of $150.00
for the replacement service. I can ship at that price for clocks up to 22" long ($375.00 total).
B-3 M-31-rotor rebuilding $150.00 (A 2-year warranty)
Labor on movement $150.00 (No warranty because it is cleaned and not overhauled)
Shipping via UPS ground $75.00
Total $375.00
There is usually a saw like 2 blade system in the clock to secure the chime rods
for shipping. Please be sure that is engaged for safe shipping. If they are gone or
not there then I use a piece of small bulb-ed bubble wrap and fold it over once and
then weave it in and out of the chime rods. A one inch wide strip is all that is needed.
This is easy to remove and prevents the chime rods of rattling during shipping and
breaking. If one or more breaks then that adds $150.00 to install a set of tuned rods
which has to be done because replacing only one or two rods throws the whole
tune out of pitch.
One thing you can do before you send in the motor (coil, field, & rotor) is to take
a Multimeter or Volt/Ohm meter, these are less than $20.00 at any hardware store, and
with no current on the clock, set the meter to Ohms and touch the two leads to the end
of the wires or the posts on the coil where the wires connect and see if you get a
reading. Just about any reading is a good one. But if you get no reading what-so-ever
then the motor's coil is dead and you'll need a replacement coil.
I'll not ship the rotor 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.
I have a quick guide for extraction and installation of the "B" rotor. Click on the
Quick guide to the "B"rotor.
For return shipping I use USPS for all shipping. If you want
to use another carrier then you will have to arrange everything for shipping,
meaning I hand the box to the driver, get a receipt and nothing else.
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 4%.
The 4% 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 4% will be added to your total bill.
All of the added fees are exactly what either service charges me for taking your
credit card.
