Synchron (Hansen) Clock Motors that are no longer available.




    My business is rebuilding your original motor, when possible.


I'd first check the following to see if your Synchron (Hansen) motor is still being
manufactured.

Both the Hansen Corporation & American Time carry some of the Synchron motors.
As well as Timesavers.com.

I've even seen some NOS (new old stock) on eBay.com

BUT make sure it's NOS or you will be buying another's headache or something
that does not work at all.


There is a lot of information on the side of each Synchron motor.  Please see
this link:

    Most out of production Synchron clock motors can be saved.  I offer basically
3 levels of service.  All details are below and 1st is if the motor passes both
the continuity and heat test.  If it does then I can overhaul your motor for
$270.00 in the US.

    2nd level is if the gear box (body) is good but the motor does not pass one of
the tests.  In that case, I take a new Synchron motor and swap out your gear box
for the other and you have a "new" motor of sorts.  That costs $520.00
in the US.

    3rd level is if the motor fails either test and the gear box (body) needs to be
completely overhauled.  This costs $1,020.00 in the US.  This is overhauling the
gear box and inserting that into a new Synchron motor. I'll not know the condition
of your old gear box until I separate it from the old motor.  This results in a
Synchron motor warranteed for 2 years and not the 1/2 warranty.

    All new motors run very hot and would not pass my heat test, there is nothing I
can do about that and it's something you should know.  I do not know of any substitute.

    With each option the motor will have a 2-year warranty.

    I am able to rebuild most Synchron motors.  All of these motors cost $250.00
plus $20.00 priority mail (Canada is $45.00) and has a 2-year warranty, which brings
your total cost to $270.00.

    All motor only service requires prepayment made out to Mike Murray,
unless you don't mind waiting a year.

  The internal coil does short out over time and even if your motor passes the heat
test, I cannot be positive that your coil has the strength to do its job.  Therefore
if any original motor runs even warm then I can only offer 1/2 ($125.00) refund should
it fail during the 2-year warranty.  If I have another in stock, then I will offer to
try another but that would be the end of the warranty because I cannot offer a warranty
in perpetude on these old motors.

    I must have the old motor in all cases, otherwise I'd have hunt around in my
Synchron "boxes" and I hate hunting.  My turn time is around a 6 to 8 weeks in
all motor only cases.  If you send in the entire clock then the turn around increased
to 8 to 12 months.  If you do not send in the old motor, then there is a $100.00
charge for using one from my inventory, which will have to be rebuilt for the
additional charge of $250.00.  That's $350.00 for a motor from my inventory.

    If you want to send in the clock for motor replacement, please be advised that
your costs will increase by $205.00 from the $270.00 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 ($475.00 total).

Overhaul Synchron clock motor  $250.00 (A 2-year warranty)
Labor and cleaning of movement  $150.00 (No warranty because this is not an overhaul)
Return shipping and handling  $75.00
Total  $475.00

    The above assumes you ship the entire clock and does not include a warranty on
the movement (mechanism) because that may need to be overhauled as well.   Most
times the movement does not need to be overhauled but if it did then you're looking
at an additional $500.00 for a possible total of $825.00, then the movement would
have the same 2-year warranty as the motor.

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

    I'll not ship the motor 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 must have the old motor.  If your motor is dead then at least I'll have it to
match it to the one I'll use from inventory exactly.  Using one from inventory adds
$100.00 to the total and it to would have to be rebuild, so the time frames would
still be the same.  Please be aware that my inventory now consists of used motors
and these motors must be heat tested and then rebuild before being shipped.  This
also means that there is the potential that nothing passes and then I'll not be
able to help you.  If that happens, then I return your old motor at no charge.
So please test the motor's coil for continuity and the motor itself for excess
heat,which is explained below.


	One thing you can do before you send in the motor is to take a Multimeter or
a 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.  The motor does not have to be running
to perform this test.  But if you get no reading what-so-ever then the motor's
coil is dead and I cannot repair that specific motor.  You should still send it
in because I may have an identical one in inventory that I can rebuild.  Using
one from my inventory adds $100.00 for a total of $350.00 plus shipping.

    Even with a dead (open) reading on the Ohm meter, or one that does not pass
the heat test (below) because the internal coil is shorting and gets too hot,
there is still the possibility that I can cannibalize a new Synchron motor's
internal coil and drive motor and incorporate your old gearing.  I have done
this many times in the past but if the internal gear box is worn out see below.
This service add $150.00 for a total of $500.00 plus shipping ($520.00).

    It is extremely important you test the coil before you send the motor and
please contact me before you send a motor with a dead coil.

    I will clean and lubricate the mechanism, which will help in delivering
more power and longevity.


	If you get a reading, then plug it in for at least 4 hours and see how
hot the motor gets.  The motor does not have to be running to perform this
heat test.  If you can hold it with your fingers for 10 seconds without being
burned then the coil would be good enough to rebuilt the motor around it.
If you can't then it's not rebuildable because there are too many shorts in
the coil and the motor would not have enough torque to last or perhaps not
run at all.

    You can always have me clean and lubricate a motor that is running too
hot.  The "catch" is that I will not warranty nor guarantee it will
work more that a few minutes and the $270.00 will NOT be applicable to any
future work even if it is to replace that very same now non-working motor.
Some have taken this chance and it has worked out but that is a chance that
you will be taking if you go that route.

	If you don't want to test it with current, then I'll be happy too and
do that right off when the motor is received, so we know what we're dealing
with.  I prefer you do it and perhaps save us both some time and effort.

    Here the heat test will be not as important as how it runs once you
have it home.  There is no definitive amount of heat generation of a
Synchron because all new motors would not pass my heat test, so applying
this principal on an old motor, the real test is in the operation under
the load that will be required.  Unfortunately for both of us Synchron's
are a wait and see and may require several back and forth trips.



	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.

    I no longer offer expedited service.

        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.


If, for any reason, I cannot rebuild your motor or I cannot
salvage an exact substitute, then I'll return your motor at no charge
what-so-ever.


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

    I would like payment by, 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.

	I do accept checks, Zelle using atmosman@earthlink.net, money orders,
or I can sent a Pay Pal invoice but it will be 4% higher to cover what
they charge me.  Checks and Money Orders must be mailed to Mike Murray,
P.O. Box 562, Fossil, OR  97830-0562 but please double check the final
price with me before you send any money however you sent it.


I'd first check the following to see if your Synchron motor is
still being manufactured.

Both the Hansen Corporation & American Time and Single carry some of the
Synchron motors.  As well as Timesavers.com.
