Sessions Older 2 threaded screws for installing Clock Motors
My business is rebuilding your original motor, when possible. All of these motors cost $150.00 plus $20.00 priority mail (Canada is $45.00) and has a 2-year warranty, which brings your total cost to $170.00. 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 with any original motor I can only offer 1/2 ($75.00) 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 perpetuity these old motors. I do not know of any substitute. 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 $250.00 to the total and it to would have to be rebuild, so the time frames would still be the same. I ONLY have counter-clockwise turning motors in my stock and all run a little hot. That means that the internal coil has some shorts and because of that I'm modifying my warranty policy for those motors coming from my inventory. I will stand behind them for 2-years BUT I will only replace them once in those 2-years. Being a questionable motor, I'm not going to lock myself in for any more than that. Please be aware that these were made directional specific. This means that some will turn clockwise and some will turn counter-clockwise. I DO NOT have a replacement for clockwise turning motors. Clockwise as you look at the top of the motor as it is mounted in the clock. Here you're looking at the disc and it is facing you. In general, the clockwise motors are the older motors from the late 20's to the early 40's. After that most, if not all, Sessions 2 threaded screws for installing motors turn counter-clockwise. To be clear, the drive gear will turn clockwise as you look at it and conversely the rear disc will spin counter-clockwise when it faces you. My turnaround is 4 to 6 weeks for motor service, 6 to 8 months if the clock is sent with the motor, or if the movement is overhauled. I no longer offer expedited service.
One thing you can do before you send in the motor is to take a Multimeter or Volt/Ohm meter, these are less than $10.00 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 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 I cannot repair your motor. You should still send it in because I may have an identical one in inventory that I can rebuild. I ONLY have counter clockwise turning motors in my stock. If you get a reading, then plug it in for at least 24 hours and see how hot the motor gets. 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 $165.00 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 to and do that right off when the motor is received, so you'll know what we're dealing with. Please don't assume I have an identical motor in inventory. 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. If I do use a motor from inventory, that increases your costs by $250.00. I no longer have any complete fiber wheels (phenolic pinion) that some motors have. You'll have to contact a Horological Wheel Specialist and see if he/she can make and mount one after you do the continuity and heat test (described above). The phenolic wheel, at the end of the shaft or drive gear, does break and even disintegrate over time. I offer to send you a motor with a good one for $65.00 extra. That means that you would send me $465.00 and I'll send you the motor and then you contact a wheel specialist and have one made and then return my motor with the pinion still intact and in good shape and then I return $400.00 of your original $465.00. If I never hear from you then I keep the money you sent. No negotiations on this and this is a firm price and please don't ask for some other offer. All pricing is firm in any case.
One more possibility and that is your Sessions may be the newer model motor; Sessions Clock Motor. Please see the link given to see the difference.
If you want to send in the clock for motor or rotor replacement, please be advised that your costs will increase by $95.00 with everything else staying the same. The increase covers the increase in return shipping and insurance and includes my labor charge of $50.00 for the replacement service. I can ship at that price for clocks up to 22" long ($275.00 total). Overhaul Sessions clock motor $150.00 Labor and cleaning of movement $50.00 Return shipping and handling $75.00 Total $275.00 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 $300.00 for a possible total of $575.00, then the movement would have the same 2-year warranty as the motor. If your clock chimes, then the mechanical overhaul on the movement is $500.00 extra. 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.
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.
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 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.
